Polymethyl methacrylate is highly biocompatible. Recycled Acrylic can be formed into sheets. They are used in:
  • The construction of windows and doors,
  • The medical sector,
  • The advertising industry, and more.
Acrylic, a BPA-free alternative to PC, is non-toxic in its solid state and naturally compatible with human tissue. In the past, it was commonly used for contact lenses and is now utilized for dental implants and bone replacements.
PMMA is transparent, rigid, and less impact-resistant compared to PC. PC, on the other hand, is stronger, more impact-resistant, and has higher temperature resistance than PMMA.
