Cast Acrylic Colors
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.
Colored cast acrylic is an industry workhorse that can be manufactured in many colors and with varying levels of transparency. Cast acrylic can be easily cut, machined, shaped, or laser cut without expensive equipment while its wide range of available colors can support nearly any application.
Advantages of Cast Acrylic
Weatherability and UV resistance
Excellent dimensional stability
Lightweight
Excellent chemical resistance
Wide range of colors
Easy to fabricate; can be glued, sawed, painted, routed, drilled
Common Applications for Colored Cast Acrylic
Excellent strength and ease of machineability make cast acrylic an ideal choice for:
Signage
POP displays
Stencils
PSA mounting
Partitions and barriers
