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® polycarbonate is easy to fabricate, paint, and glue/bond. Zelux® is a registered trade name of Westlake Plastics.

Zelux® W is the Window grade (optically clear). Zelux® M is the machine grade, stress relieved (natural and black). Zelux® M-GF is glass-filled grades, 10%, 20%, 30% and 40%. FDA compliant grades and colors are available on a custom basis.
