  • CSPE/CPE blend membrane
    Patent number: 5523357
    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.

  • Method for patching single ply roof
    Patent number: 5447006
    Abstract: A low cost relatively simple method is presented for patching single ply roof membrane derived from chlorosulfonated polyethylene by using a procedure involving N-methyl-2-pyrrolidone or NMP chemical liquid activator with proper steps therebetween and subsequently completing the patching method by following standard known welding procedures. This method results in a welded seam that can be made as strong as the roof membrane itself.

  • Blended CPE/crystalline thermoplastic polyolefin membrane
    Patent number: 5229197
    Abstract: A blend of CPE and 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 bottom layer of a multilayer single ply roof with the upper layer or layers comprising known materials.
