High Temperature Die Cutting Silicone PET Protective Film
- Withstands continuous use up to 180 °C for heat-intensive die cutting, lamination, and surface protection tasks.
- Optical-grade clarity with ≥ 90 % light transmittance, ideal for touchscreens and camera lenses.
- Highly cross-linked silicone adhesive ensures consistent clean release, ultra-low residue, and no transfer.
- Excellent anti-scratch and anti-slide properties, maintaining surface integrity during handling.
- Robust dimensional stability (low shrinkage at high temps) and high tensile strength for precision processing.
- Customizable in thickness, width, release force, and roll/liner options to match exact manufacturing needs.
This transparent PET film is coated on one side with a premium, thermally cured silicone adhesive designed for high-performance industrial use. Engineered to maintain clarity, surface protection, and mechanical integrity at elevated temperatures, it’s perfect for electronics, glass, metal, and optical component processes. Each roll is die-cut precision-ready with stable release performance, no residue, and excellent surface contact.
