Subcategory: Polycarbonate; Polymer; Thermoplastic
Material Notes:
Zelux polycarbonate is a transparent engineering plastic with excellent dimensional stability and good mechanical and electrical
properties. It is 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 range of electrical applications since it has low moisture absorption and
good insulating properties.
