We are well equipped with imported production lines, including 2 calendaring production lines from Italy, 2 PVC calendaring and stretching lines from Taiwan area, 1 BOPP line from Germany, 10-meter layflat blown film equipment from USA, as well as other blown film and colour printing equipment from Japan, Denmark and Canada.
Advantages:
high crystallinity, good dispersion, easily with other material mixing etc, which major used in insulate materials
Application:It is used in cable insulation, harness wrap, and as the dielectric medium in coaxial cables. Once sintered, it seals completely to provide excellent electrical insulating properties, unsurpassed chemical resistance and excellent thermal resistance. DeWAL's unsintered PTFE tape has good drape characteristics allowing it to conform smoothly to complicated shapes. It can be used for gaskets, expansion joints, valve seals and diaphragm applications. It is available unpigmented and pigmented to match EIA colors. It has good strength after sintering and is used where chemical inertness and high temperature resistance are needed.
