PPS is a semi-crystalline, high-temperature resistant thermoplastic.

Due to its chemical structure, PPS is a very resistant polymer with very good mechanical strengths even in temperature ranges of over 200°C. In addition to low water absorption, PPS also has good dimensional stability and exhibits excellent electrical properties. Furthermore, this material is chemically very resistant even at elevated temperatures.

The most common variant as a semi-finished product is Techtron® HPV PPS*.

This modification has an excellent combination of properties in terms of wear resistance, mechanical load-bearing capacity and dimensional stability, both in contact with chemicals and at high temperatures. Techtron® HPV PPS* is used wherever PA, POM, PET or other plastics are no longer sufficient or where a more economical alternative to PI, PEEK or PAI is required in less demanding high-tech applications. Thanks to the homogeneously distributed solid lubricant, Techtron® HPV PPS has excellent wear resistance and a low coefficient of sliding friction. It overcomes the disadvantages of unfilled PPS (high coefficient of sliding friction) as well as glass fiber reinforced PPS (premature wear of the mating surface) in sliding elements.

For higher stiffness and strength at high temperatures.

This is a PPS reinforced with 40% glass fiber. Unlike unmodified PPS, PPS GF40 offers excellent stiffness and very high strength even under high temperatures. The property profile of this modified PPS includes high thermal stability, high dimensional stability, very good chemical resistance, good electrical and thermal insulation, and good resistance to sterilization. These material properties make the glass-filled PPS GF40 suitable for components that are subjected to large static loads at high temperatures over long periods of time.
