VORGESCHAEUMTE POLYPROPYLENPERLEN. |
摘要 |
In pre-foamed particles of a propylene-base resin obtained by foaming raw particles of the propylene-base resin, the relation, G1-G2>/=10%, exists between the content G1 (%) of matter, which is contained in the pre-foamed particles and is insoluble in boiling n-heptane, and the content G2 (%) of matter contained in the raw particles and insoluble in boiling n-heptane. The pre-foamed particles have excellent moldability and can hence provide with ease low-density (highly-expanded) molded articles, which enjoy superb dimensional accuracy, good surface conditions, low percent water absorption, excellent impact and chemical resistance. |
