Dow QUESTRA® WA551 High Heat Syndiotactic Polystyrene, 40% Glass Filled

 

Subcategory: Polystyrene; Thermoplastic; Polymer

Key Words: SPS

Material Notes:
QUESTRA® Crystalline Polymers are a new family of 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.
