Specification of 9200 durlon PTFE gasket
Gasket durlon 9200 PTFE
9200W Barium Sulfate/PTFE Barium Sulfate Filler with Pure PTFE Resins FILLED PTFE GASKET MATERIAL § ASTM F104: F452111- A9B5E11K6M6 application: 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 styre ne.
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
specifiedwithin 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.
OXYGEN: DURLON® 9200W has been independently tested and certified by the Federal Institute for Materials Research and Testing, Berlin (BAM) for gaseous oxygen at pressures up to 585 psi (40 bar) and temperatures up to 392°F (200ºC), and for service in liquid oxygen.
Gaskets for ox ygen 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 THERM AL CYCLING due to thermal shock and the difference of the coefficient of expansion between PTFE and steel . composition: Barium sulfate fillers are homogeneously blended with pure PTFE resins to give DURLON® 9200W its physical and mechanical properties. Independent testing has shown the fillers in DURLON® 9200W 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. typical properties: Color : Style 9200W - Granite White, branded Filler: Barium Sulfate Temperature Range: -350 to 520°F ( -212 to 271°C) Pressure, max: 1500 psig (103 bar) Fluid Services: Steam, Nitric Acid, Chlorine Dioxide, Titanium Dioxide, Hydrogen Peroxide, Liquors, Brown Stock, Sodium Doxide, Phosphoric Acid, Caustics, Hydrogen Fluoride, Chrome Plating Solutions, Refrigerants Density: 2.5 g/cm 3 (156 lbs./ft 3 ) Tensile Strength, ASTM F152: 1,920 psi (13.2 MPa) Compressibility, ASTM F36: 8 to 16% Recovery ASTM F36: 35% Sealability ASTM F37 (Fuel A): 0.01 mL/hr ASTM F37 (Nitrogen): 0.02 mL/hr DIN 3535 Gas Permeability: 0.01 cc/min TA -Luft (VDI Guideline 2440): Approved temperature of exposure: 200°C (392°F) period of exposure: 48 h test pressure (helium): 1 bar (14.5 psig) leak rate: 1.89E-5 mbar*l(m*s) period leak rate measured: 24 h BAM - Oxygen Testing: Gaseous oxygen up to 40 bar (580 psig) and 200°C (392°F) Liquid oxygen FDA Conforms to the requirements of 21 CFR 177.1550 for food and drug contact.
