Acrylic, the rigid and transparent plastic

About acrylic

Acrylic, also known as PMMA (polymethyl methacrylate), is a rigid and transparent plastic widely used in various industrial sectors. It is distinguished by its exceptional optical clarity, UV resistance and weather resistance, as well as its ease of molding. Compared to glass, it is lighter and offers better impact resistance while maintaining similar transparency.

Features

Mechanical performance

High rigidity: acrylic offers excellent dimensional stability and resistance to deformation.
Good impact resistance: although it is more brittle than polycarbonate, it remains more resistant than glass.
Ease of machining: it can be cut, drilled, and polished easily for a precise and aesthetic finish.

Thermal performance

Moderate heat resistance: it withstands temperatures up to about 80°C in continuous use.
Low thermal conductivity: it exhibits good thermal insulation properties.

Chemical performance

Good UV resistance: it does not yellow and retains its transparency even after prolonged sun exposure.
Moderate solvent resistance: acrylic tolerates certain chemicals, but can be affected by harsh solvents.

Practicality

High transparency: with 92% light transmission, it is ideal for optical and aesthetic applications.
Lightweight: it weighs about half as much as glass, making it easier to transport and install.
Easy to clean: it can be cleaned with soapy water and remains resistant to stains and superficial scratches.

Use of acrylic

Acrylic is widely used in the manufacture of signs, safety glazing, designer furniture, and sanitary protections. Its aesthetic appeal and durability make it an ideal choice for applications where transparency and weather resistance are essential.

FAQ and Comparisons

Yes, acrylic is about 10 times more impact-resistant than glass, while being lighter. However, it is more susceptible to scratches, which may require an anti-scratch treatment for certain applications.

Acrylic offers better optical clarity and superior UV resistance, while polycarbonate is more impact-resistant and can withstand higher temperatures. The choice between them depends on the specific needs of the application.

Yes, acrylic can be glued using specific adhesives such as solvent-based glues or cyanoacrylate adhesives. Proper surface preparation is essential to ensure optimal adhesion.

No, unlike some plastics, acrylic is UV-resistant and retains its transparency for many years without yellowing.

Yes, acrylic can be heated and formed into different shapes without losing its optical properties. It is often used to create pieces with complex designs.
