PVDF films exhibit exceptional chemical resistance, weatherability, flame retardancy, and piezoelectric properties. Key applications include lithium-battery separators, architectural membranes, chemical protection layers, and sensors. High processing temperatures demand outstanding corrosion resistance from extrusion equipment. PIPPL dual-alloy barrels with specialized nickel/cobalt-based alloys and low-shear conical twin screws are engineered specifically for reliable PVDF film production.
Key Features
• Dual-alloy barrel with nickel-based / cobalt-based corrosion-resistant alloy designed for fluoropolymers.
• Low-shear conical twin screw prevents localized overheating and degradation of PVDF.
• High-temperature capability suitable for processing up to 300°C and above.
• Extended service life under aggressive fluoropolymer extrusion conditions.
• Stable melt quality for uniform film thickness and consistent performance.
Product Types
PVDF films for battery separators, architectural membranes, chemical barrier films, and piezoelectric sensor films.
