| abstract |
A blend of chlorosulfonated polyethylene (CSPE) and amorphous chlorinated polyethylene (CPE) together with an additive of crystalline thermoplastic polyolefin (e.g., ultralow density polyethlene) is presented. This material is easily processed on the rolls of a rubbermill (i.e., calender) to form continuous sheets of membrane suitable for use in single ply roofing and other similar applications. In a preferred embodiment, a membrane formed from the composition of this invention is used as the upper layer of a multilayer single ply roof. |
