High temperature Teflon tape supplied by Scifluo in China is made from PTFE coated fiberglass fabric or PTFE film coated with pressure sensitive silicone adhesive or acrylic adhesive in thickness of .003” on one side . The tapes with pressure sensitive silicone has a very high operating temperature range of -73°C to +260°C and acrylic adhesive withstand -73°C to +170°C . Since PTFE coated fabric and PTFE film have non stick surface, they will be one side etched before applying adhesive, Scifluo has special etching formula to ensure strong bonding between adhesive and basic fabric or film. High temperature PTFE Teflon adhesive tape includes PTFE tape with silicone adhesive, PTFE tape with acrylic adhesive, PTFE film tape and PTFE zone tape.
PTFE Fiberglass Tape 0.25MM 10mil
Phone:+86 180 6108 1617
PTFE fiberglass tape T025 is using PTFE coated fiberglass in thickness of 0.25mm (10mil) as basic substrate, etched on one side and coated with pressure sensitive silicone adhesive in thickness of 0.05mm (2mil), thus it’s overall thickness is 0.30mm (12mil). Due to thick substrate, T025 is more starched than other types, thus more suitable to be applied on plane or large curved surface.
PTFE coating makes surface of PTFE fiberglass tape smooth and non-stick, ideal to be used as a release medium for welding and laminating machinery to cover the high temperature platens, this release medium offers proper heat transfer and prevents materials stick to machinery, helps to increase production and reduce machinery maintenance cost.

For Laminating Process
PTFE fiberglass tape is used to cover the hot platens of paper laminating machine, non-woven laminating machine, printing laminating machine, the tape provide good stickiness under high heat and don’t have residual adhesives on the platen when peel off and replace a new one. Its release property provides a nonstick surface, help to raise production and product quality.
For Welding Release
PTFE fiberglass tape is ideal to cover mould for the manufacturing of composites in the aeronautical industry, cover PVC profile heat platen during the manufacturing of PVC window, as non-stick insertion for presses in the manufacturing of abrasive grinding wheels.
