CALIBRE™ 603-3 is a branched polycarbonate resin specially designed for extrusion of profiles, corrugated sheet and very complex multi-wall sheet. CALIBRE™ 603-3 offers a very high melt strength to calibrate effectively the most complex multi-wall sheet structures, such as a seven wall sheet or more, and to calibrate effectively complex profiles and corrugated sheet. CALIBRE™ 603-3 contains a UV absorber additive, but note that sheets for outdoor applications also require a protective UV-absorption cap layer. It is recommended to coextrude a 50 µm thick cap layer, using CALIBRE™ 320UV. Main Characteristics: - Very high melt strength
- Good impact resistance
Application:- Complex multi-wall sheet
- Profiles
