Latest Patents
Hahmann's latest patents include innovations in random propylene copolymers for electric cable insulation. This invention provides an improved polyolefin that exhibits low shrinkage values and high elongation values, even after aging. The material possesses the desired electrical insulation properties and comprises partially crystalline, randomly copolymerized polypropylene with a proportion of ethylene, butene-1, and/or 1-hexene incorporated by polymerization of 1-6% by weight. Additionally, it features a xylene-soluble proportion of 2-20% by weight, a viscosity value I of 200-400 cc./g., a melt flow index value (MFI.sub.190/5) of 1-20 g./10 min., and an elongation value of above 700%. Another significant patent involves heat sealable polybutene-1 blends containing polypropylene or ethylene. These polymer blends, which consist of a major amount of polybutene-1 and a minor amount of low-pressure polypropylene or ethylene/propylene or butene-1 copolymers, exhibit improved physical properties.
