HIGH-FRICTION ROLL COVERING COMPRISING A POLYMER BLEND |
摘要 |
<p>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.</p> |
