PTFE Film Tape with Release Liner
PTFE adhesive film coated with high-temperature silicone adhesive and supplied with a release liner for easy handling, positioning and precision die-cutting in high-temperature and insulation applications.
Product Overview
PTFE film tape with release liner is produced using pure PTFE film coated with silicone pressure-sensitive adhesive and protected by a removable release paper. The liner improves handling accuracy, cutting efficiency and lamination precision while maintaining the inherent non-stick, heat-resistant and electrically insulating properties of PTFE.
Application Scope
- Precision die-cut gaskets and insulation pads
- Heat-sealing and thermal processing components
- Sliding guides and low-friction surfaces
- Non-stick surface protection
- Electronic insulation and protection layers
