Polymethyl methacrylate (PMMA) is the chemical name for acrylic. The transparent thermoplastic also goes by acrylic glass or ice rinks. The term “acrylic” is an umbrella term with various brand names and acrylic sheet types.
Make no mistake: all acrylic sheets share the same core chemical composition. But they may differ in production methods and common applications. Acrylic is commonly used as a lightweight and shatter-resistant alternative to traditional glass.
German chemists Otto Röhm and Walter Bauer first synthesized PMMA in 1933. Its commercial production began in 1936 under the brand name ‘Plexiglas.’ However, acrylics gained prominence during World War II.
The plastic was extensively employed in aircraft canopies, submarine periscopes, and gun turrets. It’s because the material is lightweight and impact-resistant. Over the decades, acrylic has evolved into a versatile material.
Acrylic is manufactured using two primary methods – cell casting and extrusion. And the outcomes are also different, resulting in various types with unique properties.
It usually possesses slight variations in thickness but features further durability and resilience. This type is preferred for high-quality displays, aquariums, and intricate designs.
They’re easy to fabricate and shape but seem slightly less durable than cast acrylic. Extruded ones are ideal for mass-production applications (signage and point-of-sale displays).
Acrylic holds a unique combination of crucial properties like endurance and adaptability. That’s why it has become a material of choice for everyday items as well as specialized uses. Cast or extruded plastic remains a valuable asset for many projects.
Perspex, Lucite, or plexiglass is a high-quality (premium) acrylic version. Almost everyone often uses the term interchangeably with acrylic. Perspex stands out for its premium manufacturing process, which is related to superior consistency and optimal performance.
Still, it’s polymethyl methacrylate (PMMA) like standard acrylic. But it comes with strict quality controls and further enhancements for high-end applications. The premium version is also known for exceptional clarity and versatility and remains a highly preferable choice.
Plexiglass has a rich history traces back to the early development of PMMA in the 1930s. It was first commercialized in 1934 by Röhm & Haas under the name ‘Plexiglas.’ The Perspex brand was later introduced, becoming synonymous with premium-quality acrylic.
Just like acrylic, Lucite also gained prominence as a material for aircraft canopies during World War II. The lightweight material’s strong properties and superb transparency led to widespread adoption. It has now evolved to cater to diverse applications.
Being a premium acrylic brand, plexiglass production maintains stringent quality control standards. The meticulous production process delivers uniform thickness, consistent color, and superior clarity.
Such qualities call for a precise laser cut for engraving and fine edges with tight tolerances. The flawless surface of Perspex sheets is particularly valued in luxury design or engineering applications.
Today, plexiglass continues to push the boundaries of what acrylic can achieve. It acts as a trusted and high-performing material across traditional and modern fields. With creative designs or structural uses, Perspex has set a benchmark for quality in acrylic materials.
Featuring the same chemical compound, the two share considerable similarities in physical properties. However, there are some subtle differences between Perspex and acrylic, which are simplified below.
It’s also available in many standard as well as specialized types to meet diverse project needs. Aside from transparency, its impact resistance, lightweight nature, and UV stability puts acrylic in a great position as a strong glass alternative.
Although chemically identical to PMMA, Perspex distinguishes itself through rigorous manufacturing with strict quality controls. Such enhancements ensure greater consistency, superior clarity, and added performance features.
It incorporates high UV resistance to prevent yellowing or discoloration even after prolonged exposure to sunlight. However, the optical finish of acrylic can vary depending on the manufacturing process (cast vs. extruded), with cast acrylic often having the upper hand.
It’s the choice where flawless visual quality seems obligatory. In addition to optical excellence, Perspex may have advanced coatings to reduce glare or enhance light transmission. Such mechanisms also distinguish Perspex from generic acrylic materials.
This particular limitation makes regular acrylic less suitable for some applications. Frequent contact with chemicals or abrasives can damage the protective sheets without coating. Fortunately, it’s possible to polish out acrylic scratches using specialized products.
Perspex is valuable in high-traffic uses (retail displays, furniture, or automotive parts). Maintaining a flawless appearance is essential for such applications. The additional scratch resistance of Perspex minimizes maintenance for longer-lasting surfaces.
Extruded acrylic seems particularly economical compared to cast acrylic. This is because continuous production can effectively reduce total manufacturing costs. Large-scale projects with appearance and durability requirements can benefit from standard acrylic to a great extent.
Although Perspex comes with higher upfront costs, the material seems a worthy investment in tasks requiring flawless execution and longevity. The enhanced performance and longer lifespan can result in long-term savings, as it reduces repair or replacement needs.
Acrylic sheets come in vast sizes, colors, thicknesses, and finishes. Such extensive ranges make the plastic an accessible and adaptable choice for creative and customized projects. Purchased acrylic can accommodate DIY enhancements even in smaller quantities.
Perspex sheets also offer a diverse range of options, including unique finishes. Luxury metallic, fluorescent, and high-impact formulations are available. But its availability may vary depending on location, often incorporating higher costs and limited access.

*Plexiglass is a trade name for methyl methacrylate polymer (acrylic materials). All plexiglass is acrylic but all acrylic sheets aren’t the same product (not commonly sold as plexiglass)*
As mentioned, acrylic glass exhibits incredible strength that makes it ideal for various applications. The strength is divided into four key types – tensile strength, impact resistance, flexural strength, and compressive strength.
It measures the amount of pulling force a standard acrylic sheet can endure before breaking. Plexiglass showcases a tensile strength of approximately 65 MPa – 70 MPa (megapascals). The value denotes an exceptionally strong plastic material.
Acrylic glass also has good flexibility, making it a shatter resistant alternative under heavy stress. It qualifies acrylic glass for applications requiring resistance to stretching or pulling forces (display cases and barriers).
It represents the plexiglass’ ability to withstand sudden shocks or forces without breaking. The clear acrylic is around 10x stronger than regular glass for additional safety and durability.
It also makes the clear plastic sheet an excellent choice for heavy impact (sports arenas or protective shields) uses. Clear acrylic also remains a dependable material for uses requiring lightweight and transparent alternatives with the additional benefit of reduced fragility.
It refers to plexiglass’s ability to bend without breaking, a property for curved or loaded applications. Plexiglass products hold a flexural strength of 110 MPa (approximately). Thus, it maintains structural integrity under bending forces.
The strength becomes especially significant in applications like signage, curved windows, and decorative panels. Plexiglass offers a combination of flexibility and durability, making it more adaptable to creative engineering demands.
It measures the material resistance to crushing and/or flattening force. Plexiglass exhibits excellent compressive strength to resist potential deformation or cracks. It’s a crucial property for applications where the material must endure weight and pressure.
You can choose plexiglass as furniture components and structural reinforcements. Compared to regular glass, plexiglass has higher compressive strength as glass is more brittle.
Aside from strength, the acrylic plastic doesn’t fall short of durability. It features impressive longevity, making the plastic a preferred material for indoor and outdoor applications.
The high resistance to UV radiation by default has been one of the plexiglass’ standout features. Standard glass may yellow or degrade over time. But the acrylic sheet is engineered to withstand prolonged exposure without significant degradation.
It also retains the original clarity with aesthetic appeal even after years of outdoor use. Special coatings can further enhance the UV resistance, making acrylic products ideal for greenhouse panels, outdoor signage, and barriers.
Plexiglass excels in outdoor environments due to its ability to endure rain, wind, and temperature. Even immense temperature fluctuations can barely mess with the plastic (with a protective coating).
It remains stable under varying climatic conditions to retain its strength and functionality. Whether you’re using acrylic products in freezing temperatures or under scorching heat, acrylic maintains structural integrity. That’s why it’s a reliable option for construction, automotive, and furniture.
Plexiglass is more prone to surface scratching than glass. It surely seems like a drawback but you can polish the plastics to restore the original, smooth, and clear finish. Manufacturers often employ protective coatings to enhance the standard scratch resistance in demanding applications.
It’s quite important for tabletops, displays, and protective shields. Despite being less resistant to scratches, the ability to get repaired rather easily adds to the material’s versatility.
The versatile plastic material shows satisfactory resistance to most household chemicals. It includes regular cleaning agents and related solvents for daily use. However, its chemical resilience is more like a standard or minimal.
It’s because the compound can degrade or react under exposure to harsh or reactive industrial solvents eventually. This limitation becomes a crucial consideration in environments involving specialized chemicals like laboratories or industrial plants.
The longevity of Plexiglass primarily depends on its intended usage and overall exposure conditions. An acrylic item can last about 10 to 30 years under favorable conditions by maintaining its strength and transparency.
However, you can expect the lifespan to get on a higher end upon indoor applications with minimal wear and tear. Meanwhile, outdoor uses put the material under stress, reducing its durability. But protective treatments can prolong its effectiveness.
Plexiglass continues to serve as an indispensable material in numerous industries and settings. Let’s check out some common applications where each one illustrates durability and strength.
There are multiple critical, influencing, or driving factors for acrylic sheet strength and performance. You must understand those aspects to make the most of plexiglass during your intended applications.
It’s one of the most crucial determinants of acrylic strength. Thicker sheets mostly possess greater strength. It allows the plastic to bear heavy loads and withstand high-impact forces. A thin plexiglass sheet seems adequate for light applications like picture frames or barriers.
In contrast, thicker sheets are crucial for demanding applications (aquarium panels and/or structural elements). Thicker materials can distribute force more evenly while reducing the risk of cracks or breaks. It makes acrylic an ideal material for load-carrying and high-impact applications.
It may sound absurd but plexiglass installation and support can significantly impact its durability. Improper mounting leads to warping, cracks, and even vibrational damage. Uneven support for the plastic initiates uneven stress, causing the material to bend or deform over time.
Over-tightened screws or fittings can create stress points, often leading to fractures. In the meantime, insufficient or loose supports in high-vibration environments can weaken the plastics. That’s why plexiglass sheets should be properly mounted using flexible gaskets and spacers.
The acrylic plastic type has a substantial influence on acrylic strength and performance. Cast acrylic sheets feature superior clarity and rigidity. The strong plastic seems less prone to bending or warping. It’s ideal for aquariums, display cases, or optical instruments.
Meanwhile, extruded acrylic sheets are slightly more flexible and easier to machine. But acrylic plastics are less rigid and may even lack the uniform strength of cast acrylic. However, the relatively low cost material works well for applications involving machining or shaping.
Prolonged exposure to environmental factors (sun, rain, moisture, air) can gradually degrade Plexiglass strength. You should look out for high temperatures, UV light, and chemical exposures from the start. Acrylic glass, being less heat resistant, becomes soft, reducing integrity.
Additional protective measures are specified in industrial settings. Despite its natural ability, extended exposure without UV-resisting coating can lead to surface degradation or micro-cracks. Harsh solvents or prolonged exposure can cause crazing to compromise the strength.
Many customers as well as some negligent manufacturers tend to overlook testing and certifications. It’s especially true for less-known and DIY projects. The acrylic sheet must meet industry standards for strength, durability, and safety.
Strength testing for Plexiglass is governed by internationally recognized standards. Obviously, the practice is led by ASTM (American Society for Testing and Materials) and ISO (International Organization for Standardization).
Such standards provide detailed and accurate guidelines. For example, ASTM D638 focuses on the material properties of plastics, including PMMA products. Meanwhile, ISO 7823 specifies testing methods for pure PMMA sheets (cast and extruded).
Certifications also play a crucial role in verifying Plexiglass’s compliance with common safety standards. ISO 9001 ensures quality management systems to guarantee consistent production and performance.
LEED certification recognizes Plexiglass’s contribution to energy efficiency and sustenance construction. ISO 14001 focuses on environmental management to validate Plexiglass’ sustainability in construction. ISO 45001 addresses occupational health and safety to ensure Plexiglass meets the industry standards.
Always clean Plexiglass with a soft cloth or microfiber towel to prevent scratches. Stay away from rough scrubbers, abrasive sponges, or ammonia products. Rinse with clean water to remove soap residue.
Meanwhile, UV-resistant coatings prevent yellowing and degradation over prolonged sun exposure. It also helps the acrylic plastic retain its clarity for outdoor uses. Anti-fog films reduce condensation for visibility in temperature-fluctuating or high-humidity settings (barriers and acrylic windows).
For minor cracks, consider using an appropriate acrylic adhesive or solvent-based glue designed for an acrylic plexiglass sheet. Implementing the sealant can fill the gap to reinforce the damage. But apply the adhesive sparingly and allow adequate curing time to ensure a strong bond. Severely cracked or heavily scratched acrylic may need replacement.
Plexiglass surely stands out among the transparent materials for dependable everyday applications. Its strength, durability, and versatility seem unmatched due to the balance of physical properties.
You’ll get impact resistance, optical clarity, and lightweight properties – all in one package. It makes plastic invaluable across diverse sectors, from protective shields and shower panels to lighting fixtures and modern furniture.
Only the high quality plexiglass can deliver reliable and consistent service in terms of safety, design, and integrity. That’s where Jumei Acrylic Manufacturing excels in the global competition with years of innovation, expertise, and satisfaction.
