Полипропилен H 949 A
Гомополимер. Для переработки методом литья под давлением

TIPPLEN H 949 A is a high melt flow controlled rheology polypropylene homopolymer. TIPPLEN H 949 A is designed for high speed injection moulding of thin - walled items such as thinwalled containers. This product contains antistatic and nucleation additives. The grade allows fast cycling during the injection moulding process and exhibits very good resistance against warpage.
