| Product Name | Polypropylene (PP) |
| Chemical Formula | (C₃H₆)ₙ |
| CAS No. | 9003-07-0 |
| Product Form | White translucent granules |
| Product Type | Homopolymer PP (PP‑H): Propylene homopolymer, high rigidity, good heat resistance, high strength. Applications: Injection molding (daily necessities, home appliance parts), drawing (woven bags), pipes.Block Copolymer PP (PP‑B): Ethylene‑propylene block copolymer, excellent impact resistance, low‑temperature resistant. Applications: Auto parts, large containers, bumpers, toolboxes.Random Copolymer PP (PP‑R): Ethylene‑propylene random copolymer, good transparency and flexibility. Applications: Transparent products, medical devices, hot/cold water pipes.High‑Transparency PP: With nucleating agent, high clarity. Applications: Transparent containers, food packaging, stationery.High‑Melt‑Index PP: High MFR, good flowability. Applications: Nonwoven fabrics (masks, diapers), thin‑wall injection molding. |
