PORON® is a microcellular urethane foam with extremely low compression set. PORON materials are high density, flexible cellular products and are manufactured by continuously casting and curing mechanically frothed urethane intermediates to the desired thickness. By controlling chemistry and density, the properties of PORON® materials can be widely varied.
PTFE material has the lowest coefficient of friction and possesses superior chemical resistance. We supply a variety of PTFE products from the industry's top PTFE producers.
- PTFE Gaskets
- PTFE Gasket Sheets
- PTFE infused tapes & sealants
- PTFE o-rings
A wide variety of gasketing products - fabricated in dozens of materials in hundreds of formulations
