Abstract: Provided is a relay box housing obtained by molding a resin composition containing (a) a polypropylene resin, (b) a polyphenylene ether resin, and (c) a hydrogenated block copolymer. The resin composition has a deflection temperature under load of 100° C. or higher and a ratio of the storage elastic modulus G?A to G?B, expressed as G?A/G?B, of 0.9 to 1.5. Multipurpose test specimens A and B are obtained from the resin composition with an injection molding method with a first multipurpose test specimen A immersed in water under predetermined conditions and a second multipurpose test specimen B not immersed. Storage elastic modulus measurement is performed on each of the test specimens A and B at 50° C. in a tensile mode to obtain the storage elastic moduli G?A and G?B.

Abstract: A polymeric composition is a blend of one or more heterophasic copolymers of propylene and ethylene produced by a multistep polymerization, wherein the heterophasic copolymers comprise a low crystalline matrix component and a soft amorphous elastomeric component, in which both the matrix component and the soft amorphous elastomeric component contain greater than 55% by weight propylene; one or more additional elastomeric components selected from the group of an ethylene/?-olefin C3-C20 copolymer with a total ethylene concentration of greater than or equal to 65% by weight; and a propylene/?-olefin C2, C4-C20 copolymer with a total propylene concentration of greater than or equal to 65% by weight; 5-65% by weight of the total composition of one or more inorganic or organic reinforcement materials; and 0.01-4% by weight of the total composition of a maleic anhydride grafted polypropylene compatibilizer or coupling agent. The polymeric composition has a low crystallinity of less than 30 J/gram measured by DSC.

Abstract: The present invention relates to polypropylene compositions with a balance of high strength, good clarity, excellent stress whitening resistance, and excellent impact properties—especially at low temperatures—for use in demanding plastics applications. Blends consist of both homopolymer and random copolymer polypropylene fractions, as well as propylene-ethylene elastomers and styrenic based elastomers. The invention also covers molded articles made from these blends.

Abstract: A support cart for a machine screw may comprise a frame and a plurality of trolleys. The frame may have a pair of tracks and a caster assembly. The caster assembly may have a first position where the frame does not contact a surface, such as a floor, allowing the frame to be movable. The caster assembly may also have a second position which allows the frame to contact the surface, such as a floor, rendering the frame to be substantially stationary. The plurality of trolleys may include a base, an adjuster, a support bracket, and a plurality of rollers. The trolleys may be movable along the tracks of the frame via the plurality of rollers. A height position of the support bracket may be adjustable relative to the base via the adjuster.

Abstract: A thermoplastic polyolefin composition comprising, based on the total mass of the composition, 10-75% by mass of high density polyethylene (HDPE), 8-30% by mass of elastomer, and 5-45% by mass of filler, wherein the composition has a Melt Flow Rate of 1.0-20 g/10 min according to ISO 1133 at 190° C./2.16 kg. The thermoplastic polyolefin composition is produced in a method comprising batch mixing or continuous mixing the HDPE, elastomer, and filler to form a melt blend, and cooling the melt blend to give the product. In addition, the thermoplastic polyolefin composition can be injection molded to form an article, which is preferably an automotive body part. The thermoplastic polyolefin composition exhibits improved heat deflection temperatures, improved ductile failure mode in low temperature atmosphere, improved flexural modulus and lower specific cost compared to polypropylene based thermoplastic polyolefin compositions.
