PMMA - Acrylic Plastic Sample

Polymethyl methacrylate (PMMA), commonly known as acrylic or acrylic glass, is a transparent thermoplastic noted for its excellent optical clarity, weather resistance, and lightweight strength. Unlike glass, PMMA is amorphous and can transmit up to 92% of visible light, making it a popular substitute where transparency and reduced weight are required.

Key properties include high tensile strength, low water absorption, and resistance to UV degradation. PMMA is easily machined, thermoformed, and joined with adhesives, allowing complex shapes and assemblies.

Common applications encompass signage, glazing, lenses, lighting fixtures, medical devices, and display screens. Its combination of clarity, durability, and ease of fabrication ensures PMMA remains a leading material in optical and architectural uses.
