PTFE Strong Double Sided Tape with acrylic adhesive, heat resistant
Strong Double Sided Tape coated with PTFE use skived PTFE film as basic material, PTFE film is made of suspended PTFE resin by molding, sintering and cooling on a dust-free production line, then turning and rolling to PTFE film tape. Mutiflon will make special surface treatment on both sides of film, then coating two sides with modified pressure sensitive acrylic adhesive. This double side self-adhesive tape has high tensile and dielectric strength. 
Features of Basic PTFE Film
Chemical properties
Weather resistance: Radiation resistance and low permeability
Non-flammable: The oxygen limit index is below 90
Acid, alkali and organic solvents resistance
Oxidation resistance: Resist the corrosion of strong oxidant
Physical properties of Strong Double Sided Tape
Density: 2.1~2.3g/cm3, PTFE has very low surface energy
Mechanical property
PTFE maintains excellent mechanical features in wide temperature range of -196～260℃, as a kind of perfluorocarbon polymer, it do not become brittle under low temperature.
Electrical performance
PTFE film tape has low dielectric constant, high breakdown voltage and arc resistance
