Neoprene rubber fireproof sealing gasket

Neoprene is a rubber compound noted for its various oil and chemical resistant properties. Unlike some rubber compounds, Neoprene can withstand burning and high temperatures – standard grade Neoprene is normally rated for operating temperatures up to 93°C (200°F); beyond this range, the compound may stiffen. If heated to 260°C (500°F), Neoprene will begin to burn.
