Title:
SEALANT
Document Type and Number:
Japanese Patent JPS62273279
Kind Code:
A
Abstract:
A sealing composition is described on a base of butyl rubber, polyisobutylene and, if required, soot, which, in contrast to known sealing compositions of this type, contains 30 to 55 % by weight of kaolin. The butyl rubber component preferably consists of a mixture of unsaturated and cross-linked butyl rubber, while the polyisobutylene component preferably consists of a mixture of polyisobutylenes of different molecular weight. In addition to the said components, the sealing composition according to the invention may contain still further components such as pyrogenic silicic acid and polyethylene of low density, together with the usual components. The new sealing composition is particularly suitable for use in cable sleeves, particularly cable sleeves for telecommunications cables.
