PTFE-encapsulated silicone

PTFE-encapsulated silicone combines the elasticity of silicone with the chemical resistance of a PTFE surface.

Suitable for

Aggressive fluids where tight sealing is required.

Typical applications

Acids: mineral and organic acids
Solvents: aromatic and aliphatic solvents, ketones, aldehydes, esters, chlorinated hydrocarbons, de-icers
Electroplating: aggressive acids and salts, residual sludges, waste water, neutralisation, caustic soda, ferric chloride
