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.

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
 
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.
