They are especially suitable for customers looking for a matte surface finish that does not require painting, and therefore is a cost-effective solution for automotive interiors. For the requested control panels, the Terblend N NG02 EF grade was identified as particularly suitable. It is an 8% glass fiber reinforced UV-stabilized ABS/PA blend with enhanced dimensional stability, rigidity and high flowability. Glass-fiber reinforced grades such as Terblend N NG02 EF exhibit lower shrinkage and, as a result, higher dimensional stability. Despite the glass fiber percentage, it offers a high quality surface with matte appearance and excellent haptics. In addition, Terblend N NG02 EF has a very low moisture absorbance in comparison to polyamide.
The solution of one of the two manufacturers consists of a second component containing a certain amount of TPE (Thermoplastic Elastomer).
"Apart from control panels, Terblend N NG02 EF is used for many automotive interior applications, for instance, for defrost vents. Other blends of Ineos Styrolution's Terblend N are used for applications like loudspeaker grills, seat covers, or venting devices, depending on the respective requirements," says Christophe Ginss, Sales Director Automotive with global coordination role.
