Polyplastics introduces new RENATUS (R) PET grades for auto exterior components

KUALA LUMPUR, Nov 16 -- Polyplastics Group has announced the introduction of two new RENATUS (R) polyethylene terephthalate (PET) grades which deliver superior mechanical properties, appearance, and weather resistance for automotive exterior components.

This reaffirms Polyplastics' strong commitment to PET as a key pillar of its extensive resin business portfolio, according to a statement.

The two new glass-reinforced grades, RH030 (30 per cent glass-filled) and RH045 (45 per cent glass-filled), maintain their jet blackness and reduce whitening on the surface of molded articles in outdoor environments, making them ideally suited for applications such as automotive side mirrors and rear wiper arms/blades.

Since PET parts are not painted, weathering degradation can occur over time. The glass filler can start to float and the jet blackness can decrease.

Accelerated weather-resistance testing demonstrates that Polyplastics' new PET materials maintain lower index values than their competing products, thus indicating whitening is being reduced.

RENATUS (R) RH030 and RH045 PET are glass fibre-reinforced grades, but they can still produce molded articles with good surface appearance because of their superior mold transferability during molding.

Recent company testing shows that when compared to standard grade PBT-GF30, RH045 (PET-GF45) exhibits higher surface gloss even though it has a large amount of glass fibre added to the formulation.

Meanwhile, in terms of mechanical performance, PET typically has superior properties compared to PBT. At similar glass loadings, RH030 and RH045 PET grades have higher mechanical properties including greater tensile strength, flexural modulus, and deflection temperature under load compared to PBT grades.

Polyplastics Co Ltd is a global leader in the development and production of engineering thermoplastics, with product portfolio including POM, PBT, PPS, LCP, GF-PET, and COC.
