Durlon® 9200 Barium Sulfate/PTFE

Barium sulfate fillers are homogeneously blended with pure PTFE resins to give DURLON® 9200 its physical and mechanical properties. Independent testing has shown the fillers in DURLON® 9200 to be more evenly dispersed than filled PTFE with layered construction. The result is more consistent physical and mechanical properties without the voids, separation and chemical compatibility problems found in layered filled PTFE. It is suitable for use in steel flanges, will not exhibit the cold flow problems associated with virgin or generic skived PTFE or the hardness problems of some other filled PTFE products. It has excellent sealability, cuts easily and separates cleanly from flanges after use.

Application

• DURLON® 9200 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. Style 9200 (granite white, branded) conforms to FDA requirements.
• OXYGEN: DURLON® 9200 has been independently tested and certified by the Federal Institute for Materials Research and Testing, Berlin (BAM) for gaseous oxygen at pressures up to 40 bar (585 psi) and temperatures up to 200°C (392°F), and for service in liquid oxygen. Gaskets for oxygen service can be supplied from distributor stocks, providing proper cleaning procedures for oxygen service are followed before installation.
• 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.

• Max Continuous Temperature: 260°C (500°F)

Durlon® 9400 Carbon/PTFE

DURLON® 9400 is made of pure PTFE resins combined with carbon fillers homogeneously dispersed throughout the compound. DURLON® 9400 does not exhibit the cold flow problems associated with virgin PTFE yet has excellent sealability, flexibility, non-sticking and cutting characteristics. DURLON® 9400 also demonstrates good electrical conducting properties.

Application

DURLON® 9400 gasket material is a high performance filled PTFE designed for use in piping and equipment in chemical, pharmaceutical, food and other general industrial applications where resistance to highly aggressive chemicals (including hydrofluoric acid) is required. Style 9400 conforms to FDA requirements. It can also be used as gasketing for anhydrous hydrogen fluoride (AHF) in railroad tank cars and in plants as a material of construction where barium sulfate filled PTFE may not prove suitable

Specifications

• Min Temperature: -212°C (-350°F)
• Max Temperature: 288°C (550°F)
• Max Continuous Temperature: 260°C (500°F)
