Thermoplastic, flexible mix of polymers

Abstract: 1. A thermoplastic, halogen-free, flame-resistant polymer mixture, particularly for cable sheathing having an elastomer component of ethylene copolymer or ethylene terpolymer with a proportion of at least 38 % od comonomer and a plastomer component containing at least 70 % of internal ethylene monomer, wherein, in relation to the weight of all the polymer components, the proportion of the elastomer component amounts to at least 15 % and the proportion of the plastomer component amounts to 40 % to 85 %, and having a mineral filling of from 180 % to 320 % of the weight of the polymer mixture, which filling contains at least one metallic hydroxide, and also having carboxyl groups, characterized in that the carboxyl groups are introduced in a form bonded on a polymer in such a manner that this polymer contains 0.5 % to 14 % by weight of COOH groups.

Elastomer or plastomer article - reinforced with bare aramid fibres alternating with flock coated aramid fibres

Abstract: Aramide fibres are often used as reinforcement for plastomer or elastomer hoses, belts, etc. because of their exceptional high tensile strength and low elongation. Attempts have been made to prevent premature failures, caused by their low abrasion resistance and transverse stability by coating them with an elastically deformable coating of flocks. The increased dia. is, however, often not acceptable because of space limitations. The difficulty can be overcome by the simple expedient of alternating bare fibres, made of aromatic aramide, with aramide fibres, coated with flocks, both in the horizontal and vertical direction.
