  • Monolithic belts containing ethylene-alpha-olefin copolymers
    Publication number: 20040168757
    Abstract: Monolithic belts (i.e. without woven fabric insert), in particular monolithic conveyer belts and drive belts, which consist of a thermoplastic material, containing a copolymer with a ratio of weight average molecular weight Mw to number average molecular weight Mn of 5.0:1 to 1.5:1, which show creep resistance while at the same time having significantly reduced material costs. The copolymer can in particular be produced by means of a metallocene “single-site” catalyst.
