摘要： An overmolded thermoplastic article includes a substrate portion molded from a thermoplastic resin compound and an overmold portion molded from a thermoplastic elastomer compound. The thermoplastic resin compound includes thermoplastic polymer resin. The thermoplastic elastomer compound includes thermoplastic elastomer and polysiloxane as a mold release agent, and is free of wax. The overmold portion is bonded onto the substrate portion with a peel strength at least comparable to that of an overmolded thermoplastic elastomer compound containing wax as a mold release agent instead of the polysiloxane. Undesirable effects observed with the use of wax as a mold release agent in overmolded thermoplastic elastomer compounds such as blooming and ease of scratching/marring can be reduced, while desirable properties such as silky feel of the surface of the overmold portion and good bonding of the overmold portion onto the substrate portion can be at least maintained.

摘要： A tackifier to modify the Tan Delta of midblock segments of a hydrogenated styrenic block copolymer in a thermoplastic elastomer compounds aids in rendering the HSBC TPE more effective as an overmolding compound having a low percentage compression set value when measured at the high temperature compression set standard. The HSBC TPE can overmold effectively upon polar polymeric substrates depending on the bonding agent chosen.

摘要： Pultruded fiber reinforced polymer composite is disclosed, having a blend of conventional pultrusion resins and a rigidsol. The replacement of some of the conventional pultrusion resin with the rigidsol does not adversely affect mechanical properties but does enhance affinity of the pultruded part to a polyvinyl chloride-containing capstock.

摘要： A thermoplastic elastomer compound includes polyolefin elastomer, high softening point tackifier, and, optionally, styrenic block copolymer. When styrenic block copolymer is present, the weight ratio of polyolefin elastomer to styrenic block copolymer is no less than about 1:1. The polyolefin elastomer has a POE Tan Delta Peak Temperature, the styrenic block copolymer has a SBC Tan Delta Peak Temperature, and the thermoplastic elastomer compound has a Compound Tan Delta Peak Temperature. The Compound Tan Delta Peak Temperature is greater than the POE Tan Delta Peak Temperature. When styrenic block copolymer is present, Compound Tan Delta Peak Temperature is also greater than the SBC Tan Delta Peak Temperature. The thermoplastic elastomer compound exhibits useful damping properties at or above room temperature and can be formed into plastic articles, including foamed plastic articles and/or crosslinked plastic articles, which can be useful for a variety of damping applications.

摘要： Thermoplastic articles are molded from thermoplastic polyurethane compounds including blends of aromatic polycaprolactone thermoplastic polyurethane and aliphatic polycaprolactone thermoplastic polyurethane. The thermoplastic articles can have enhanced stability against exposure to ultraviolet (UV) light relative to thermoplastic articles molded from thermoplastic polyurethane compounds including only aromatic polycaprolactone thermoplastic polyurethane as the thermoplastic polyurethane component. Additionally, the thermoplastic articles can have good stain resistance, good clarity (i.e., low haze), and other desirable properties.

摘要： A thermoplastic elastomer compound includes styrenic block copolymer and high softening point tackifier. The styrenic block copolymer has a Copolymer Tan Delta Peak Temperature and the thermoplastic elastomer compound has a Compound Tan Delta Peak Temperature. The Compound Tan Delta Peak Temperature is greater than the Copolymer Tan Delta Peak Temperature. The thermoplastic elastomer compound exhibits useful damping properties at or above room temperature while also advantageously possessing improved stability for processing and/or applications at high temperatures and upon exposure to weathering.

摘要： A composite laminate is made by providing at least a first composite ply and a second composite ply, each having longitudinally oriented fibers in a thermoplastic matrix. The second composite ply is disposed on, and in transverse relation to, the first composite ply. Preferably, the second ply is disposed at 90° relative to the first ply. An article can be manufactured by providing a core material and applying a reinforcing material to a portion of the core material. The reinforcing material is a reinforcing composite ply or a composite laminate as described herein. Optionally, the core material is a prepreg that may be a composite laminate.

摘要： A completely non-halogenated flame retardant polycarbonate compound includes polycarbonate, non-halogenated termini-functional chemical such as vinyl-terminated siloxane and non-halogenated hydride-functional polysiloxane as non-halogenated drip suppressant ingredients which react in the presence of heat to form a drip suppressant adduct, and potassium 3-(phenylsulfonyl)benzenesulfonate as a non-halogenated char former. The compound can achieve a UL 94 rating of V-0 at a thickness of at least 3.2 mm and otherwise achieves no dripping/igniting of the cotton indicator during that test.
