Abstract
A water resistant sealing material suitable as a gasket or valve seal is described. The sealing material comprises modified chemically exfoliated vermiculite (CEV) in a proportion of 30-70% w/w sealing material and a filler in a proportion of 70-30% w/w sealing material, and optionally other additives in a proportion of 0-10% w/w sealing material. The modified CEV comprises water resistance enhancing monovalent cations. The sealing material is particularly useful to provide improved water resistance in gaskets and valve seals.
