Latest Patents
Ernst Poppe holds a patent for a molded soft elastomer/hard polyester composition with noise damping properties. This invention provides a molded composition that exhibits improved noise damping characteristics. It is made from a blend of a soft thermoplastic polyether elastomer and a hard polyester resin, which is reinforced with a fibrous or particulate filler. The molded composition features an inhomogeneous structure, with a surface part rich in elastomer and depleted in polyester resin and reinforcing filler compared to its inner part. This is achieved through monocomponent injection molding of the blend, where only the polyester resin contains the reinforcing particulate filler. The resulting molded composition has a flex modulus Fm in the range of 0.5 to 10 GPa and maintains a sufficient minimum tan delta damping factor over a temperature range of -50°C to 170°C.
