Airtech International (Huntington Beach, Calif.) recently introduced Wrightlon 3700, a release film designed for low-cost applications. The film properties are said to include elongation to 550 percent with a tensile strength of 7,000 psi/48.26 MPa. Designed to release from epoxy, polyester and vinyl ester resin systems, the film also is available in P16 perforation style for infusion applications. Also new is Teflease MG2E Yellow pressure-sensitive tape, an extruded polytetrafluoroethylene (PTFE) film coated with silicone adhesive. It will release from most resin systems and is designed for use on tooling blocks and any other application in which high elongation and release is necessary. It reportedly conforms to critical contours and mold surfaces while offering multiple releases.
