CompaFid PPS compound added to DimeLika Plast’s product range

DimeLika Plast has expanded its portfolio with a high-strength material, the semi-crystalline high-performance plastic PPS (polyphenylene sulphide). CompaFid compounds are available in standard market modifications. The standard range includes glass fibre-reinforced and glass fibre/mineral-reinforced models based on ‘linear’ and ‘cross-linked’ PPS base polymers.

“We can also make individual adjustments to products for smaller quantities. The same applies to customer-specific colour settings,” explained Hans-Dieter Voss, managing director of DimeLika Plast. “From the product idea right through to series production, we offer our customers comprehensive technical advice and develop customer-specific products when required.”

PPS is a semi-crystalline high-performance plastic, which has good mechanical properties even at temperatures beyond 200°C. Continuous use at up to 240°C is possible depending on the load. Short term, the plastic will also withstand loads of up to 270°C. The chemical resistance of PPS in relation to almost all solvents, many acids and alkalis, and to a limited extent against atmospheric oxygen, even at high temperatures, is also claimed to be excellent.

In addition to low water absorption, polyphenylene sulphide is also said to exhibit excellent dimensional stability and inherent flame retardant properties. It is also said to have outstanding electrical properties, is highly impermeable to most liquids and gases, has a low creep tendency even at higher temperatures and is suitable for long and narrow moulded parts and complex tool shapes due to its good fluidity.

CompaFid compounds are particularly well suited to mechanical, electrical, thermal and chemical high-stress moulded parts in the electronics and vehicle sectors.
