polycarbonate


Zelux® polycarbonate is an engineering plastic with excellent dimensional stability and good strength and stiffness over a wide range of service temperatures. Zelux® is often used for structural applications when clarity and impact strength are essential including lenses, manifolds, site glasses, and machine guards. Zelux® is used for a wide variety of electrical applications since it has low moisture absorption, good insulating properties, and an excellent flammability rating. Zelux® is easy to fabricate, paint, and glue.

The following physical property information is based on typical values of the base polycarbonate resin.

Zelux® W

*In addition to our standard capabilities, Westlake also has the ability to process custom resins in various sizes and colors with some exceptions.
