DOCATRON (polyphenylene sulphide, PPS) product family features

PPS, or polyphenylene sulphide, offers excellent performance at high temperatures in demanding applications. Its dimensional stability, chemical resistance and mechanical properties are outstanding, even at temperatures around 200 degrees Celsius. Available in plate and rod formats. Reinforced grades with even higher values are available, such as PPS with glass fibre (PPS GF or GF40), PPS HPV with lubricant and glass fibre (specifically recommended for food applications), and PPS PVX with lubricant and reinforced with carbon fibre and graphite.

Some important features

High mechanical strength and hardness
High application temperature range (230 - 260 °C)
Good wear resistance even at high temperatures
Low friction coefficient
Good size retention
Excellent chemical and hydrolysis resistance
Good electrical insulation and favourable dielectric behaviour
Durable flame resistance
Resistant to high levels of radioactive radiation

Main areas of application

Its application is particularly advantageous where heat resistance, flow resistance, abrasion resistance, chemical resistance have to be met at the same time and other plastics (such as PA, POM, PET, PEI, PES and PSU) are no longer suitable.
They can be used to make advanced products to replace PEEK, PAI and PI for lower stresses and requirements.
Typical applications are in machinery components subjected to high mechanical and chemical stress in the medical, aerospace, nuclear, chemical, electrical and automotive industries.

Machining technology

Chipping (turning, milling, drilling, sawing): carbide and diamond tools should be used. Cooling is recommended with cutting speeds of v = 250-500 m/min for turning and milling, v = 10-30 m/min for drilling.

Gluing: is feasible.
