Material Notes:
It is a non-reinforced amorphous polymer whose main features are its high thermal, electrical and mechanical properties which are typical of a crystalline polymer. Compared to its "brother" PES it has lower thermal properties, although this level is still high when compared to most other engineering plastics.Features:Resistance to high temperature. Resistance to hydrolysis and steam. Mechanical properties : tensile stress, flexural strength, E.modulus Chemical resistance Electrical properties TransparencyWeak Point:The cost is higher than conventional engineering plastics. It does not stand UV rays and is therefore not suitable for outdoor applications.Application:Electrical: the very good insulating and dielectric properties make it irreplaceable in many electrical applications: plates for circuits, coils, insulators. Mechanical: it is used for high performance applications such as bearings and precision gears at low as well as high temperatures. Chemical: the use in this field is ideal thanks to its high chemical and thermal resistance. Good resistance to mineral acids, alkali and salt solutions. PSU is attacked by esters, chlorine and aromatic hydrocarbons. Food contact: it is physiologically inert and is therefore used for parts in contact with food, even at high temperature. The excellent chemical properties make it suitable for pump components, flanges, etc. which are in contact with food liquids.Information provided by Omnia Plastica s.p.a. for semifinished products such as sheet, rod, and tube.
