Omnia Plastica - Polyethersulphone - PES
Subcategory: Polyethersulfone; Thermoplastic
Material Notes:
This high performance engineering plastic is an amorphous polymer with exceptional mechanical features (typical of crystalline polymers). It also has excellent chemical, electrical and thermal properties.Features: - Resistance to high temperature (heat deflection temp. 200° C.)
- Mechanical properties: very high tensile stress, flexural strength, E.modulus
- Flame resistance
- Very high chemical resistance
- Electrical properties
- Transparency
Weak Point:The cost is higher than conventional engineering plastics. Application: - Mechanical: the dimensional stability and heat resistance are very high. Compressive and flexural strength combined with the tensile stress are typical of a super-polymer. It is consequently used for high performance applications such as bearings and precision gears at low as well as high temperatures.
- Electrical: the very good insulating and dielectric properties make it irreplaceable in many electrical applications.
- Chemical: PES is ideally suited for use in the chemical industry thanks to its high chemical and thermal resistance. It also possesses excellent resistance to acids, alkali and salt solutions.
- Food contact: it is physiologically inert and therefore it is 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. It withstands hydrolysis and sterilisation as well as the continuous heat cycles in pressure cookers.
