Fast Heat Exchange Rate Chill Roller with 1℃ Surface Temperature Control for Capacitor Film
Product Description
Surface Temperature Control 1℃ Chill Roller with Double Shell Construction for BOPP/BOPET Applications
Chill Roller Basis Information
Chill rollers are essential components in biaxial oriented stretching lines for BOPP, BOPET, BOPA, BOPS, and BOPI films, as well as longitudinal stretching systems. They perform the critical function of cooling and solidifying molten polymers during film formation, ensuring uniform thickness, flatness, and premium quality output.
Our chill rollers feature specialized internal circulation channels designed to maximize thermal conductivity and temperature control precision. This advanced technology can increase casting productivity by 20%-30% while providing consistent thermal regulation - essential for high-speed film production requiring exact material solidification.
