Durlon^® 9200W

Durlon^® 9200W is a filled PTFE gasket material designed for use in aggressive chemicals. Including caustics, hydrogen peroxide, sodium hypochlorite, nitric acid, liquors and digester in pulp and paper service. Applications in the chemical, pharmaceutical, and plastics industries include butadiene, hydrofluoric acid, vinyl chloride, methyl methacrylates, and styrene. It is also used extensively in railroad tankcar applications and can be used where resistance to highly aggressive chemicals is required.

Durlon^® 9200W is also used for hydrofluoric acid service at moderate concentrations and temperatures or where a barium sulfate filled PTFE gasket material is specified within a temperature range of –350°F to 520°F (-212°C to 271°C), or with pressure up to 1500 psi (10.3 MPa).

Style 9200W (granite white, branded) conforms to FDA requirements.

Note: That as a class, PTFE gasket materials are not recommended in liquid oxygen services where there is thermal cycling due to thermal shock and the difference of the coefficient of expansion between PTFE and steel.
