PP plastic, chemical name: Popular Chinese name: Polypropylene (smaller PP) specific gravity: 0.9-0.91 g/cm3 molding shrinkage: 1.0-2.5% molding temperature: 160-220°CPP is a molding type with high foaming, and the comprehensive performance of PP is better than that of PE material. PP products are light, tough and chemically resistant.
