Polysulphone(PSU)

Polyphenylene sulphide (PPS)(deep blue)
This reinforced, internally lubricated polyphenylene sulphide grade demonstrates an excellent combination of properties including wear resistance, load-bearing capabilities and dimensional stability, when exposed to chemicals and high temperature environments. TECHRON HPV PPS finds its applications where PA POM, PET, PEI and PAI are over-engineered and a more economical solution must be found.
Thanks to the uniformly dispersed internal lubricant, TECHTRON HPV PPS exhibits excellent wear resistance and a low coefficient of friction. It overcomes the disadvantages of virgin PPS caused by a high coefficient of friction, and of glass firbre reinforced PPS which can cause premature wear of the counterface in moving-part applications. It goes without saying that these features, in combination with its excellent chemical resistance, offer numerous application possibilities to TECHTRON HPV PPS in all kinds of industries.

Main characteristics:

 •  High mechanical strength, stiffness and creep resistance, also at elevated temperatures
 •  Excellent chemical and hydrolysis resistance
 •  Excellent wear and frictional stability
 •  Excellent resistance against high energy radiation (gamma and X-rays)
 •  Good UV-resistance
 •  Inherent low flammability
 •  Good electrical insulating and dielectric properties.
