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 EA503 is a 30% glass filled, ignition resistant polymer suitable for Electrical and Electronic applications.Data provided by Dow Chemical.
