KYNAR - Semi-Rigid PVDF Heat Shrinkable Tubing
Applications
It is especially suitable for environments that require abrasion and high temperature resistance. KYNAR is made of polyvinylidene fluoride and has particularly outstanding performance on friction properties. It is often designed for high temperature and chemical resistant environments and for the covering of automotive control wires.
