| abstract |
The present invention relates to heat-shrinkable articles, including tubes, O-ring, sleeves, sealants possessing outstanding elastomeric properties, ability to elastic deformation beyond 200 %, and ability to precisely and completely recover design dimensions, while possessing significantly improved mechanical properties, in particular higher tensile strength; to a method of making the same, and to a method of using the same including reverting to a shrunk state. The heat shrinkable article is made of a composition comprising at least one fluorinated thermoplastic elastomer comprising at least one elastomeric block and one thermoplastic block, iodine and/or bromine cure sites, at least one organic peroxid, and at least one polyunsaturated compound. |
