Dow Questra® WA551 High Heat Syndiotactic Polystyrene, 40% Glass Filled (discontinued **)
Categories:	Polymer; Thermoplastic; Polystyrene (PS); Syndiotactic Polystyrene (SPS); Syndiotactic Polystyrene (SPS) with Glass or Carbon Fiber
Material Notes:	QUESTRA® Crystalline Polymers are semi-crystalline engineering thermoplastic resins produced from styrene monomer using a proprietary metallocene catalyst system. These syndiotactic polymers are very different from conventional styrenics in structure, and properties, exhibiting excellent heat resistance with a melting temperature of 270.C, excellent moisture and chemical resistance together with a unique combination of exceptional electrical properties, toughness and processability. QUESTRA crystalline polymers are typically used as moldings, films, and fibers in Electronic, Electrical, Automotive, Consumer and Industrial, Filtration, Optical/photographic film and Specialty fiber/non-woven markets. QUESTRA WA551 is a 40% glass filled polymer suitable for Automotive Electronic Systems. Data provided by Dow Chemical.
