GASKETS

摘要

A spirally wound gasket is described. The gasket includes a sealing strip ( 11 ) wound into a spiral and a support strip ( 10 ) wound into a spiral in such a manner that the spiral of the sealing strip is formed interposed between the coils of the supporting strip. The sealing strip comprises a resilient material, the resilient material comprising a CEV component in a proportion of at least 25% w/w of the sealing strip. The CEV component is at least partially derived from dry CEV, and the sealing strip does not include a carrier strip in one aspect. In another aspect, the CEV component is at least partially derived from dry CEV, and the sealing strip has a moisture level of between 3-20% w/w of the sealing strip resilient material during winding into the said gasket. A method of producing a sealing strip is also described.
