POLYPLASTICS CONFIRMS PPS CAN BE USED FOR BUMP-OFF MOLDING

KUALA LUMPUR, Sept 19 (Bernama) -- Polyplastics Co Ltd, a leading global supplier of engineering thermoplastics, has completed a study which confirms the viability of polyphenylene sulfide (PPS) for bump-off molding of automotive engine cooling systems.

Polyplastics' linear DURAFIDE (R) PPS, which already offers superior performance over rivals like nylon 66, now has bump-off molding capabilities to eliminate deburring.

Previously, PPS had limited use in bump-off molding of engineering parts due to its fragility.

In a statement, Polyplastics said it found that materials with high bending-fracture strain in high-temperature environments are suited for bump-offs in terms of both damage and deformation.

The company also observed that improvements in fracture strain in high-temperature environments are possible by reducing filler, adding elastomer and utilising high-molecular-weight PPS.

Polyplastics' DURAFIDE PPS appears to be suited for bump-offs from the standpoint of toughness in high-temperature environments. Among DURAFIDE PPS materials, high-molecular-weight 1130A1 (GF30%) and 1140A1 (GF40%) appear to be useful for bump-offs. 

Polyplastics believes that DURAFIDE PPS boosts product reliability, and that bump-offs reduce the deburring process and facilitate greater design freedom.

DURAFIDE PPS also delivers high heat resistance with a continuous service temperature of 200°C to 240°C.

It also offers greater chemical resistance versus fluoropolymers, and greater dimensional stability and reduced hydrolysis/water absorption compared to nylon 66.
