Abstract
The gasket includes a sealing strip comprising a resilient material, the resilient material comprising a chemically exfoliated vermiculite (CEV) component in a proportion of at least 25% w/w of the sealing strip, the said CEV component being at least partially derived from dry CEV, wherein the sealing strip does not include a carrier strip, made by the process of the application of a wet sealing strip material to a forming sheet to form a layer; partially drying the wet sealing strip layer on the forming sheet; removing the layer from the forming sheet; and (d) cutting the layer into strips suitable for use in the formation of a spirally wound gasket.
