Pure white PTFE sheet without any impurities

Description
The chemical, electrical and thermal performance of PTFE is second to none among any other available plastics. So it is known as " the King of Plastic" . It is among the most widely used of all the fluoropolymers.

Characteristics
-Work well between -180°C and 260°C
-Superior chemical resistance
-Very low coefficient of friction
-Longest aging life in plastics
-Good dielectric properties
-Non-toxic
-Non-stick

Applications
Bearings
Gaskets
Sealing rings
Wear rings
Friction pads
Insulators
Chemical resistance linings
Medical apparatus such as hoppers, beakers
