PPS GF40 - Polyphenylenesulphide
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
- electrical: very good insulating power and dielectric
properties make it irreplaceable for many applications in this field
- chemical: very good chemical resistance
- food contact: it is not used in contact with food
