Polytetrafluoroethylene-Expandable (PTFE-E)

PTFE-E or E-PTFE is a PTFE. made by a special process that could produce uniform and highly fibrillated microstructure with a great lot of fibre running in multi-direction. This microstructure create a soft, pliable and yet tough soft PTFE sheet that has excellent resistance to most industrial chemical, creep relaxation and cold flow properties. The material process excellent chemical resistance ability, but weaker against substances that contain melted alkali metal and fluorine at liquid or gas states.

Properties

Excellent chemical resistant
High service temperature
Non-contaminating, non-toxic
Food grade ( FDA21 CFR177)
Low sealing compress pressure
Highly compressible

Application Example

It is virtually suitable to use for any type of industries for sealing application.
Especially for glass lined vessels, glass lined reactors, pressure filters, large pressure vessels, large directional flanges with severe irregularities and heat exchangers
