  • Patent number: 10839979
    Abstract: A cable comprising a covering having two or more different sheath layers, with the covering providing superior chemical and weathering resistance, and excellent surface feel. In a preferred embodiment, the outermost sheath layer of the covering is a thermoplastic elastomer essentially free of a flame retardant material, yet the covering achieves desirable flame retardant performance due to the presence of an inner sheath layer comprising a thermoplastic elastomer and a flame retardant, preferably halogen-free flame retardant. The outermost sheath layer also exhibits sought-after surface qualities. Methods for producing the coverings and flame retardant cables are disclosed.

    Abstract: The invention relates to a process and an apparatus for the preparation of a crosslinkable rubber mixture for vehicle tires, lines, drive belts and other industrial rubber articles, which can be carried out at least semicontinuously. The present invention is based on the discovery that the experiments known from the prior art to carry out the batchwise process usually used at least partly continuously have failed in particular because of the problem that the crosslinking agents have to be mixed rapidly and homogeneously with the base mixture, also referred to as rubber base mixture, without the mixture consisting of the base mixture and the crosslinking agents heating up too strongly. According to the invention, attention was therefore focussed on reliably mixing the base mixture homogeneously with the crosslinking agents and minimizing the mixing time. A first measure for achieving the desired aim consists in first mixing the crosslinking agents with one another before they are mixed with the base mixture.

  • Publication number: 20140128535
    Abstract: A method of functionalizing reclaimed elastomer material is described. The method involves subjecting particles of the reclaimed elastomer material to shear at temperatures less than 100° C. such that inter-chain bonds of the reclaimed elastomer material are cleaved wherein the particles of the reclaimed elastomer material have a size of 60 mesh or smaller. The reclaimed elastomer material can be subjected to shear in the presence of a modifier which selectively promotes the cleavage of inter-chain bonds in the reclaimed elastomer material. A functionalized reclaimed elastomer material made by a method as described above and an elastomer compound which comprises the functionalized reclaimed elastomer material are also described.
