バーミキュライトホイルを製造するための方法
Document Type and Number:
Japanese Patent JP2004533535
Kind Code:
A
Abstract:
The invention is concerned with gasket sealing foils having a sealing layer with enhanced properties which is based upon chemically exfoliated vermiculite. The method of producing a sealing foil for gaskets is described. The method comprises the steps of:
(a) the application of a wet sealing foil material to a forming sheet to form a layer;
(b) partially drying the said wet sealing foil layer on the forming sheet;
(c) removing the said layer from the forming sheet to form a core free gasket sealing foil; and
(d) forming, preferably cutting, the layer into at least one suitable shape for use in the formation of a gasket. The sealing foil comprises a resilient material, which comprises a CEV component in a proportion of at least 25% w/w of the sealing foil, the CEV component being at least partially derived from dry CEV. The sealing foil layer may be combined with a gasket support layer prior to or after the cutting step.
