HEAT RESISTANT MICROPOROUS MATERIAL PRODUCTION AND PRODUCTS

摘要

Microporous nylon materials which retain near constant time to hydrosaturation during and after heating to temperatures necessary for sealing together a plurality of surfaces, and the synthesis thereof. Nylon lacquer (1) comprising a mixture of liquid nylon (46), solvents and nonsolvents, is dispersed on a fabric substrate (4), then precipitated in quench bath (6) to form a laminate, from which a wash in rinse tank (7) removes the nonsolvents and forms the microporous material.
