Teflon-based and Teflon coated glass cloth tapes are noted for their excellent chemical resistance. These tapes are able to withstand high temperatures and can be used for different purposes like protective covering, coating, etc.
PPI 751 is based on a Teflon® (PTFE) film coated with a silicone adhesive. The PTFE backing has very good flexibility with both exceptional chemical resistance and excellent releasing properties. Ideally suited to applications that require low friction/easy release. Examples include protective covering for rollers, cylinders, plates, belts for polyethylene extrusions, and hotmelt coatings. It can operate at temperatures up to 200°C (392°F) with a short term heat resistance up to 260°C (500°F).
PPI 752 a thicker version of PPI 751 with all the same chemical and heat resistance properties.
PPI 761 A high quality Teflon® (PTFE) coated glass fabric with a silicone adhesive. The non-stick PTFE backing resists salts, acids, and solvents. PPI 761 can operate at temperatures up to 260°C (500°F) and possesses high mechanical strength due to the glass fabric reinforcement. It is recommended for all specialist applications (e.g. masking, protecting) which require exceptional heat or chemical resistance. PPI 761 provides a non-stick surface for many applications (e.g. release surface on heat sealing/plastic welding equipment).
PPI 762 A thinner version of PPI 761 with all of the same chemical and heat resistance properties. It is more suited to applications where the tape must cover curved or irregularly shaped surfaces.
