Cast Acrylic Clear
Cast acrylic is a versatile material commonly known as plexiglass found in many applications across numerous industries. Cast acrylic is a thermoplastic polymer created through polymerization, a chemical reaction between a specific catalyst and a monomer.
Cast acrylic is an excellent option for anyone seeking superior clarity and strength without sacrificing versatility due to its higher optical clarity than glass. It’s also 17 times stronger and 10 times more shatter-resistant than glass while still being easily machined, shaped, or laser cut without the worry of noxious off-gassing or burning.
