GASKETS

摘要

A gasket is described. The gasket comprises a sealing strip wound into a spiral. The sealing strip is formed from a resilient layer which comprises particles of a chemically exfoliated vermiculite (CEV). The sealing strip includes a flexible carrier strip to which the sealing strip is bonded. Generally, the level of CEV falls within the range 25-80% w/w of the sealing layer. A method of producing such a gasket is also described.
