Compatibility of sealants with PMMA and PC
Polymethyl methacrylate (PMMA) and polycarbonate (PC) are plastics that are frequently used in construction and industry. Both products are supplied in (glass) clear and colored versions. There are also glass fiber reinforced versions. The materials are hard, rigid, and have high impact and scratch resistance. The materials are used in: bulletproof glass, safety glass, pool covers, bathroom furniture, light domes, aquariums, terrariums, etc. With respect to PC, PMMA has the advantage that the product is clearer in the transparent version, less yellowish and more scratch-proof. PC is more resistant to mechanical impact and has many uses. It is widely used in anti-burglary products and bulletproof glazing systems. Well-known brand names of PC are Lexan® from GE Plastics and Makrolon® from Bayer. PMMA is known as Plexiglas®, which is a trademark of Rohm and Haas.
