Saint-Gobain COHRlastic® CF3320 Reinforced Solid Rubber
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	Description: COHRlastic® CF silicone solid rubber reinforced with fiberglass is a dimensionally-stable, durable material for press pads, belting and gasketing. It is available in six constructions. CF 3320, available in three thicknesses, was developed to meet AMS 3320. Consequently, 3320 has lubricating oil resistance and excellent compression set resistance. All data based on a 0.0625 inch test sample.(Also available in 3/32, 1/8; Thickness shown is for silicone rubber. Fiberglass thickness = 0.014".)
