| GC168 – 7790/858 is a grey, 15% mineral filled polypropylene compound intended for injection moulding. The product is available in natural (GC168) and black (GC168 – 8229) but other colours can be supplied on request. The good flowability of GC168 – 7790/858 makes it very easy to process even for complicated parts. The material displays excellent gloss and antistatic properties. The product contains a metal deactivator. GC168 – 7790/858 is intended for component, which require very good surface quality, rigidity, very good impact, low shrinkage and high dimensional stability.
