The linear Polyphenylensulfide belongs to the semi-crystalline materials and offers a very high mechanical capacity, thermal- and chemical resistance distinguished at the same time (usual operating temperature up to approximately +300 °F), high dimensional stability and creep strength. The LOI belongs to the highest of the Polymers. By the reinforcement with glass fibres strength is achieved, which is comaparable with light metal. PPS closes the gap between the technical synthetics and PEEK with its strength and economy.
- very high strength and rigidity
- high hardness
- high thermostability
- high dimensional stability
- very high chemical resistance
- very good insulating properties
- high weather resistance
- high resistance to hydrolysis
- very low moisture absorption
Components in the machine-making, pump parts, fan parts, impellers, parts in the fuel and automotive sector, valve seats and valve seals.
The 40% glass fibre reinforced PPS has an improved dimensional stability and higher stiffness which can be compared with light metal applications. Usual operating temperature up to approx. +860 °F.
- high thermal resistance
- great dimensional stability
- higher surface stiffness
