| CALIBRE™ 302-5 is a standard linear polycarbonate resin designed for solid sheet extrusion. CALIBRE™ 302-5 is also suitable for the production of low complexity multi wall sheet, such as two and three wall sheet. CALIBRE™ 302-5 contains a UV absorber additive, but note that sheets for outdoor applications also require a protective UV cap layer. It is recommended to coextrude a 50 µm thick UV cap layer, using CALIBRE™ 320UV. Main Characteristics: Excellent optical properties Exceptional impact resistance High heat resistance Applications: Solid and multi-wall sheet applications&& |
