Taconic manufactures high performance PTFE coated fiberglass tapes and fabrics. These materials serve as a cost-effective release surface for hand lay-up and open mold composites.

PTFE coated fabric flexible release liners conform to the mold while its nonstick coating allows clean removal from the molded composite part. In open mold processing, the mold or tool is lined with PTFE coated tape which provides an advantage over fabric for complex shapes in that it is conformable and will stay firmly in place. Once the PTFE lined mold is filled with resin and composite material, curing occurs and the PTFE tape releases cleanly from the
tooling.

Taconic’s PTFE tapes and fabrics replace other manually applied release agents that are labor intensive to use and must be reapplied before each lay-up. PTFE tapes and fabrics provide a more consistent release and may also last for several pulls from the mold, providing additional time and cost savings.

Another advantage of using PTFE tape and fabric as a release surface is the elimination of harmful chemicals that are often used to clean other release agents off the parts after manufacturing.
