PMMA (acrylic) films feature ultra-high transparency, excellent weatherability, and superior surface hardness. Used in optical films, advertising, electronic panels, and decorative materials, PMMA film production demands extremely clean processing and strict temperature control to avoid yellowing and black spots. PIPPL low-shear conical twin screws and mirror-finished dual-alloy barrels are optimized for optical-grade PMMA film extrusion.
Key Features
• Low-shear progressive screw design prevents thermal yellowing of PMMA.
• Mirror-finished dual-alloy barrel minimizes material hang-up and black-spot formation.
• Excellent self-cleaning performance reduces cross-contamination between runs.
• Stable melt quality ensures consistent optical clarity and thickness uniformity.
• Long service life under continuous optical-film production conditions.
Product Types
Optical-grade PMMA films, protective films, decorative films, and light-diffusion films in clear or tinted versions.
