摘要:
A thermoplastic composition includes a poly(arylene ether), a hydrogenated block copolymer, a pre-blend of a thermoplastic vulcanizate and a hydrogenated block copolymer, an ethylene/alpha-olefin copolymer, and a hydrocarbon resin. Pre-blending the thermoplastic vulcanizate with a portion of the hydrogenated block copolymer was found to markedly improve the flame resistance and physical properties of the composition compared to those of compositions in which the thermoplastic vulcanizate and hydrogenated block copolymer are separately added to the final compounding process. Addition of hydrocarbon resin further improves the balance of flame retardancy and physical properties.

摘要:
A durable coating which reduces ice adhesion and minimizes ice accumulation includes a polymeric binder and a film forming lubricant. The polymeric binder is selected from a fluoropolymer or silicone polymer having one or more reactive groups. The film forming lubricant is a lubricous fluoropolymer or silicone polymer. Methods of applying a durable coating are also disclosed.
摘要:
A thermoplastic composition includes the product of melt kneading a composition including a poly(arylene ether), a polyolefin, an acid-functionalized hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene, and a polyamine compound. The composition exhibits substantially improved chemical resistance compared to a corresponding composition lacking the polyamine compound. Methods of preparing the composition and articles prepared for the composition are also described. The composition is particularly useful for fabricating halogen-free tubes for sheathing automotive wiring harnesses.
摘要:
A flame retardant additive composition comprising a phosphoric acid salt selected from the group consisting of melamine phosphate, melamine pyrophosphate, melamine orthophosphate, diammonium phosphate, monoammonium phosphate, phosphoric acid amide, melamine polyphosphate, ammonium polyphosphate, polyphosphoric acid amide and combinations of two or more of the foregoing; a metal hydroxide; and an organic phosphate. The flame retardant additive is useful in a wide range of thermoplastic compositions.
