PPS GF40 - Polyphenylenesulfide
Crystalline polymer based on polyphenylene sulfide with the addition of 40% glass-fibre. Very high rigidity, stiffness and flexural strength. The temperature resistance is very high: up to 240° C. Its abrasion resistance is among the very best. It is used for small precision parts where a very high dimensional stability is required in both the electrical and nuclear industries.
FEATURES
High temperature resistance (beyond 240° C.)
Modulus of elasticity and flexural strength are very high
Excellent abrasion resistance
Flame resistant
Electrical properties
Colour: brown
WEAK POINT
Very high rigidity and brittleness. Difficult to machine
APPLICATION
Mechanical: the dimensional stability and heat resistance are both excellent and the flexural and compressive strength are exceptional. Components have very good wear resistance but are highly brittle. It is used for high performance small parts such as bearings, precision gears, etc, at both low and high
temperatures.
Food contact: it is not used in contact with food
Electrical: very good insulating power and dielectric properties make it irreplaceable for many applications in this field.
Chemical: the chemical resistance is poor. It is not used for this purpose
