WATERPROOF RUBBER SHEET

摘要

A fusion bondable waterproof sheet having a first ethylene- alpha -olefin rubber layer which has a high crosslinking rate and is changed to a crosslinked layer and a second ethylene- alpha -olefin rubber layer which has a low crosslinking rate and is changed to a partly crosslinked layer, the crosslinking of both sheets being carried out after compositing and integrating them, which sheet has good fusion bondability and good bond strength at high temperature.
