Tubular article made of polymer material with elastic characteristics useful for electrical industry, where the polymer material is equipped with an embedded single or multi-layered strengthening supports made of textile materials

摘要

The tubular article made of polymer material with elastic characteristics, where the polymer material is equipped with an embedded single or multi-layered strengthening supports made of textile materials, is claimed. The first textile material (7) receives strengthening function within the strengthening supports. The first textile material is combined with a second textile material (9) under formation of textile composite. The second textile material receives the adhesive function within the strengthening supports and is connected to the surrounding polymer material. The tubular article made of polymer material with elastic characteristics, where the polymer material is equipped with an embedded single or multi-layered strengthening supports made of textile materials, is claimed. The first textile material (7) receives strengthening function within the strengthening supports. The first textile material is combined with a second textile material (9) under formation of textile composite. The second textile material receives the adhesive function within the strengthening supports and is connected to the surrounding polymer material. The second textile material is used in raw form or is adhesively activatable. The article consists of 55-70 wt.% of first and second textile materials and if necessary 45-30 wt.% of further textile material. The first and the second textile material and if necessary further textile material are formed from yarn or fibers and form a cord fiber, filament fiber or twine fiber (5) or form short strengthening support particles, which are short fibers. The strengthening support particles are uniformly distributed within the polymer materials. The polymer material is an elastomeric material based on vulcanized rubber mixture that consists of non-extended rubber component and/or extended rubber component. The polymer material comprises a styrene based thermoplastic elastomer, olefin-based cross-linked or partially cross-linked thermoplastic elastomer or olefin-based completely cross-linked thermoplastic elastomer, and mixture ingredients.
