Title (EN) HIGH-FRICTION ROLL COVERING COMPRISING A POLYMER BLEND
(FR) GARNITURE DE CYLINDRE A HAUT FROTTEMENT COMPRENANT UN MELANGE POLYMERE
Abstract: front page image
(EN)The present invention embodies covers, especially those used in the textile industry. Some covers are made of a polypropylene comprising less than 90 percent isotactic linkages and a thermoplastic block copolymer comprising hard segments of polystyrene combined with soft segments. Other covers are made of metallocene-catalyzed polyolefins and thermoplastic block copolymers. The durable-abrasion resistant covers typically have a high static coefficient of friction.
(FR)L'invention concerne des garnitures, spécialement celles utilisées dans l'industrie textile. Certaines garnitures sont fabriquées en polypropylène comprenant moins de 90 % de liaisons isostatiques et un copolymère bloc thermoplastique comprenant des segments durs de polystyrène combinés aux segments souples. D'autres garnitures sont fabriquées en polyoléfines catalysées par métallocène et en copolymères bloc thermoplastiques. Les garnitures résistant à l'abrasion et durables présentent normalement un coefficient de frottement fortement statique.
