Further Details:

PTFE (Polytetrafluoroethylene) is an inert material with excellent chemical resistance, electrical and thermal insulation. They can be operated in temperatures from cryogenic to 2600 Degree Celsius offering non-corrosive, non-wetting, non-contaminating and odorless operation. PTFE gaskets by Goodrich Gasket are mainly used in the presence of aggressive chemicals such as acids, bases and solvents. Offering versatility and convenience in the form of a highly conformable flexible strip is the expanded PTFE gaskets by Goodrich Gasket Pvt Ltd that is used in non-standard flange applications. It is also a backup sealing option under non availability of conventional gaskets.

We at Goodrich Gasket offer PTFE gaskets with excellent chemical resistance and inherent cleanliness making the product a suitable sealing agent against aggressive media or feedstock contaminated areas. The presence of an adhesive backed strip eases the installation in large or complex flange applications, such as air conveying and solvent recovery systems.

Expanded PTFE gaskets are suitable for temperatures ranging up to 5000F and for cryogenic applications like hydraulic systems, water supply systems, ventilation ducts, fan housing, fume ducts, pneumatic systems, engine case doors etc.

Goodrich Gasket offers the following width and thickness of expanded PTFE gaskets:-
