Product details
Clear pmma acrylic polymer sheet
 
Transparent acrylic sheet (also known as PMMA sheet, polymethyl methacrylate) is a thermoplastic engineering plastic with excellent optical properties and mechanical strength. Acrylic is a polymer material made of methyl methacrylate (MMA) monomer through bulk polymerization or suspension polymerization. Its molecular structure gives the material excellent transparency, weather resistance and processing performance. The light transmittance of transparent acrylic sheet can reach 92% (close to 92% of glass), but the weight is only half of that of glass, and the impact strength is 10-15 times that of ordinary glass, making it an ideal material to replace glass.
 
Acrylic sheet has the following typical characteristics:
  • ​Ultra-high light transmittance (92%), close to optical glass
  • Excellent mechanical strength (impact strength is 10-15 times higher than glass)
  • Good weather resistance (no yellowing after long-term outdoor use)
  • Easy to process (can be thermoformed, cut, and engraved)
  • Economical (more cost-effective than engineering plastics such as PC)

Transparent pmma sheet has become an ideal material to replace glass with its ultra-high light transmittance, excellent mechanical properties, good weather resistance and easy processing. It is widely used in many fields such as construction, advertising, lighting, transportation, and medical treatment, especially in occasions that require high transparency and safety.
​Future development trend:
​Environmental modification: Develop lead-free stabilizers to improve environmental performance
​High-performance products: Develop special functional sheets such as antistatic and self-cleaning
​Smart surface: Integrated LED, touch and other functions
Transparent acrylic sheet will continue to play an important role in the trend of "plastic replacing glass", providing high-performance, beautiful and economical solutions for various industries.
