Abstract
A gasket material comprising a fibre component, a rubber component and a further resilient material is described. The further resilient material comprises chemically exfoliated vermiculite (CEV). A novel process of production is also described. The product has high stress retention and excellent sealing performance at high temperatures. Preferably, the gas permeability of the gasket material is less than 1.0 ml/min and the hot creep of the gasket material is less than 15%.
