Poly (oxy -1 ,4- phenylsulfonyl -1 ,4 -phenyl) after chemical nomenclature or colloquially polyethersulfone ( PESU or PES ), is a belonging to the group of high-performance thermoplastic polysulfones.

Representation

The synthesis of poly (oxy-1 ,4- phenylsulfonyl -1 ,4 -phenyl) can run both a Polysulfonylierung and a polyether.

Properties

It is transparent, resistant to hydrolysis and chemical resistant. Poly (oxy -1 ,4- phenylsulfonyl -1 ,4 -phenyl) is the superior polysulfone (PSU ) in the chemical resistance and impact resistance. It is mainly used in high performance parts (medical equipment, automotive, aerospace, electrical and electronic components) used.

Poly (oxy -1 ,4- phenylsulfonyl -1 ,4 -phenyl ) is currently experiencing a resurgence as a material for the production of baby products (especially bottles ). The hitherto conventional polycarbonate plastics have been associated because of the contained bisphenol A with health risks. In contrast to the clear - transparent polycarbonate bottles, the polyethersulfone alternatives are light honey color.
