Abstract
(DE) Der Artikel mit einem mehrschichtigen Grundkörper mit elastischen Eigenschaften besitzt wenigstens eine Innenschicht A und wenigstens eine textile Festigkeitsträgerschicht B und wenigstens eine Zwischenschicht C und wenigstens eine Außenschicht D, wobei wenigstens eine Zwischenschicht C des Grundkörpers aus einer Kautschukmischung aufgebaut ist, die Chloroprenkautschuk (CR) oder chlorsulfoniertes Polyethylen (CSM) oder alkyliertes chlorsulfoniertes Polyethylen (AC SM) oder chloriertes Polyethylen (CM) oder Chlorbutylkautschuk (CIIR) oder Brombutylkautschuk (BIIR) oder Polyepichlorhydrinkautschuk (CO; ECO; ETER) oder bromiertes Copolymer aus Isobutylen und Paramethylstyrol (BIMS), jeweils alleine oder in Kombination, und 3 bis 40 phr wenigstens eines intumeszierenden Flammschutzmittels enthält und wobei die Zwischenschicht C sich in direktem Kontakt zu einer textilen Festigkeitsträgerschicht B befindet.
(EN) The article, comprising a multilayer main part with elastic properties, has at least one inner layer A, at least one textile reinforcement layer B, at least one intermediate layer C, and at least one outer layer D. At least one intermediate layer C of the main part is made of a rubber mixture which contains chloroprene rubber (CR) or chlorosulfonated polyethylene (CSM) or alkylated chlorosulfonated polyethylene (AC SM) or chlorinated polyethylene (CM) or chlorobutyl rubber (CIIR) or bromobutyl rubber (BIIR) or poly epichlorohydrin rubber (CO; ECO; ETER) or a brominated copolymer of isobutylene and paramethylstyrene (BIMS), in each case alone or in combination, and 3 to 40 phr of at least one intumescent flame retardant, said intermediate layer C being in direct contact with a textile reinforcement layer B.
(FR) Selon l'invention, l'article, comprenant une partie principale multicouche ayant des propriétés élastiques, comporte au moins une couche intérieure A, au moins une couche textile de renforcement B, au moins une couche intermédiaire C, et au moins une couche extérieure D. Au moins une couche intermédiaire C de la partie principale est constituée d'un mélange de caoutchouc qui contient du caoutchouc chloroprène (CR) ou du polyéthylène chlorosulfoné (CSM) ou du polyéthylène chlorosulfoné alkylé (AC SM) ou du polyéthylène chloré (CM) ou du caoutchouc chlorobutyle (CIIR) ou du caoutchouc bromobutyle (BIIR) ou du caoutchouc polyépichlorhydrine (CO ; ECO ; ETER) ou un copolymère bromé d'isobutylène et de paraméthylstyrène (BIMS), dans chaque cas seul ou en combinaison, et de 3 à 40 pce d'au moins un ignifugeant intumescent, ladite couche intermédiaire C étant en contact direct avec une couche textile de renforcement B.
