The main difference between PTFE tape and PTFE film tape is their form, use and characteristics.
Form and Use
Polytetrafluoroethylene Tape: This tape is usually made of polytetrafluoroethylene (PTFE) resin coated on a substrate, and common substrates include fiberglass yarns. It has excellent high temperature resistance, chemical corrosion resistance and stickiness resistance. Polytetrafluoroethylene tape is widely used in packaging, thermoplastics, composites, sealing and thermal bonding, electronics and electrical industries, and is especially suitable for occasions where anti-stickness, corrosion resistance and insulation are required.
Polytetrafluoroethylene film tape: This tape is usually made of PTFE film, with high temperature of use, excellent chemical resistance, non-stick and peel properties, as well as good dielectric and barrier properties. It can be used as a single-layer film or multi-layer structure with other polymer mixture layers, suitable for a variety of occasions where high temperature, chemical corrosion resistance and good insulation properties are required
characteristic
Polytetrafluoroethylene tape:
High temperature resistance: Can maintain stable performance at extreme temperatures, such as in the range of -196℃ to 300℃
Anti-adhesive: Smooth surface, excellent anti-adhesive properties
Chemical corrosion resistance: Can withstand corrosion of various chemical substances
Insulation Performance: It has good electrical insulation performance, suitable for electronic and electrical industries
Polytetrafluoroethylene film tape:
Dielectric performance: Excellent dielectric performance, suitable for microwave circuit board production and electrical/electronic cable
Barrier characteristics: It can be used as an air-tight and liquid-tight barrier layer for compensators, expansion joints, corrugated pipes, etc.
Multi-layer structure: Different polymer or mixture layers can be configured to show excellent drape and fit
