Saint-Gobain COHRlastic® CF4444 Reversion Resistant 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 4444 has a specially formulated rubber compound to give better reversion resistance. The reinforcement is a special crush-resistant fiberglass, making the product excellent for press pads in high-temperature and pressure lamination applications. 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 = 0.135".)
