Pressure Seal 23711 Ethylene Propylene
Categories: Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes: Compound 23711 is a 70 durometer black colored high strength EPDM rubber formulated specifically for use in alkalis and acids, with the exception of concentrated sulfuric and nitric acid. It exhibits good resistance to heat and compression set. This, coupled with its good low temperature flexibility, allows for its use over a wide temperature range. Compound 23711 is also very resistant to polar materials such as water, phosphate esters, ketones and alcohols. The phosphate ester resistance makes it very useful for automotive brake fluid applications. Further, it demonstrates excellent resistance to weathering and steam. It is also a peroxide cured compound. This compound will meet or exceed the specifications listed and has the following physical properties: ASTM D2000 2 AA 720 A13 C12 EA14 F17 EA14; 3 AA 720 B13 B33 C12 F17 EA14; 4 AA 720 A13 B13 B33 C12 F17 EA14; 5 AA 720 A13 B13 B33 C12 F17 EA14; 2 BA 720 C12 F17; 3 BA 720 A14 B13 C12 F17 F19; 4 BA 720 A14 C12 F17; 5 BA 720 F17 F19 C12; 6 BA 720 B13 C12; 3 CA 710 A25 B44 B35 EA14 C32 F17 F18 F19 G11 G21; 4 CA 720 A25 B35 EA14 C32 F17 F18 F19 G11 G21; 5 CA 720 A25 B35 EA14 C32 G11 G21; 2 DA 720 A26 B36 C32 EA14 F19 G11 G21; 3 DA 720 A26 C32 EA14 F19 G11 G21
Compound 23711 is UL approved per JOHX2 for water, steam, air and inert gasses. This compound is also suitable for use in anhydrous ammonia.
