Lanmar #632-14R is a 14 mil PTFE coated fiberglass tape with an acrylic adhesive with blue release liner. 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: 5000V. Insulation Class 155.

Specifications: 14 mil PTFE backing / 16 mil total thickness. Break strength: 400/225 lb/in. Elongation: <5. Adhesion: 50 oz/in.

Includes a blue release liner for clean handling and precise application without adhesive contact during positioning.

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 with release liner. Available custom slit to width.
