zelux-wZelux® polycarbonate is an engineering plastic with excellent dimensional stability and good strength and stiffness over a Zelux Wwide 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® W is the Window grade (optically clear).
