Lanmar #632-3 is a 3 mil PTFE coated fiberglass tape with an acrylic adhesive. The woven fiberglass backing is PTFE coated for a non-stick, chemically resistant surface. The acrylic adhesive is the right choice where a silicone adhesive would be incompatible with downstream processes, such as certain coating, painting, or electronics applications.

The acrylic adhesive provides aggressive bonding to metal, rigid plastic, and most hard surfaces. Rated from -40 to +350°F. Dielectric strength: 3000V. Insulation Class 155.

Specifications: 3 mil PTFE backing / 5 mil total thickness. Break strength: 70/50 lb/in. Elongation: <5. Adhesion: 50 oz/in.

Common applications include heat sealer bar wrapping, packaging equipment platen covers, conveyor belt surfaces, roll-to-roll release liner applications, and uPVC window welding. Supplied in roll form. Available custom slit to width.
