*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)*

Types of Strength in 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.

01. Tensile 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).

02. Impact Resistance

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.

03. Flexural Strength

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.

04. Compressive Strength

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.

Durability Factors of Acrylic Sheets

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.

a. UV Resistance

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.

b. Weather Resistance

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.

c. Scratch Resistance

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.

d. Chemical Resistance

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.

e. Lifespan

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.

Factors to Affect Acrylic Plexiglass Sheet 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.

i. Sheet Thickness

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.

ii. Mounting/Support Design

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.

iii. Type of Acrylic (Cast vs Extruded)

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.

iv. Environmental Stress

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.

Testing and Certification for Plexiglass

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).

Preparing Acrylic Samples for Testing

Certifications for Safe Applications

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.

Maintenance of Plexiglass

  • Preserving Clarity and Strength: Proper and periodic cleaning is mandatory to maintain clarity and structural integrity. A solution of warm water and mild soap is enough to remove dirt and grime.

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.

  • Protective Coatings or Films: They offer an additional layer of defense to enhance plexiglass durability against everyday rigors (wear and environmental exposure). Specialized coatings significantly improve resistance to scratches, making acrylic more suitable for high-contact applications.

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).

Using Acrylic Adhesives to Patch Minor Damage (Cracks)
  • Repairing Minor Scratches or Cracks: It’s possible to repair minor damages (scratches or small cracks) easily to restore appearance and functionality. A commercial acrylic polish or plastic cleaner can buff the surface to minimize the scratches. Deeper scratches may need fine-grit sandpaper followed by a polishing compound for a smooth finish.

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.

Conclusion

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.
