Latest Patents
Rothhöft's latest patents include a multimodal polyethylene molding composition designed for producing pipes with improved mechanical properties. This innovative composition features a multimodal molecular mass distribution and consists of 45 to 55% by weight of a low molecular weight ethylene homopolymer, 20 to 40% by weight of a high molecular weight copolymer comprising ethylene and another olefin with 4 to 8 carbon atoms, and 15 to 30% by weight of an ultrahigh molecular weight ethylene copolymer. This formulation, prepared in the presence of a Ziegler catalyst through a three-stage process, is highly suitable for producing pipes with excellent mechanical properties.
Another significant patent involves polyolefinic compositions for injection-molded drainage systems. This polypropylene composition comprises 78-84% by weight of a crystalline propylene polymer, 8 to less than 13% by weight of an elastomeric copolymer, and 8 to less than 13% by weight of polyethylene. The composition exhibits a flexural modulus value higher than 1400 MPa, a melt flow rate (MFR) of 1.5 to 5.0 g/10 min, and an Izod impact resistance at 0°C of more than 6 kJ/m according to ISO method 180/1A.
