Zelux®
(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.
