Japanese engineering plastics producer Polyplastics (Tokyo; www.polyplastics.com) introduced two glass-fibre reinforced PET grades to its “Renatus” product line designed for exterior automotive applications that require weather resistance, mechanical properties and surface appearance.

“Renatus PET RH030”, a 30% glass-filled material and “Renatus PET RH045”, a 45% glass-filled have transferability during moulding, which provides good surface appearance of moulded articles, the company claims. The materials have shown to reduce whitening on the surface of moulded articles in weather-susceptible environments. The materials produce items with a good surface appearance compared to a standard 30% glass-filled PBT, even with the large glass-fibre content.

Renatus PET RH030 and RH045 deliver higher mechanical properties of tensile strength, flexural modulus and deflection temperature under load compared to a PBT with the same amount of glass fibres added, according to Polyplastics.
