Polycarbonate films and sheets offer high transparency, excellent impact resistance, and good flame-retardant properties. Widely used in electronic protective films, optical films, packaging, and advertising light boxes, PC film extrusion requires precise melt temperature control and gel-free plasticization. PIPPL low-shear conical twin screws combined with mirror-finished dual-alloy barrels deliver optical-grade surface quality and stable thickness distribution for continuous high-speed production.
Key Features
• Low-shear conical twin screw ensures uniform melt without gels or degradation.
• Mirror-polished dual-alloy barrel provides superior surface finish for optical and protective films.
• Accurate multi-zone temperature control keeps melt temperature fluctuation within ±2°C.
• Self-cleaning design supports rapid color and grade changeovers, reducing downtime.
• Long service life under continuous film extrusion conditions.
Product Types
Thin PC films, optical-grade sheets, diffuser sheets, protective films, and flame-retardant films in clear, translucent, or colored versions.
