Virgin Grade

PTFE is considered one of the more stable materials from a thermal point of view; with a service temperature of between -200 and 260°C PTFE does not change its own physical and molecular properties.

It possesses excellent dielectric properties and is practically inert to all chemical products. Due to its extremely low co-efficient of friction the surface is non adhesive but with chemical etching to one side it can easily be bonded to a suitable surface.
