PP Impact Copolymer for Injection Molding
This low‑flow impact‑copolymer polypropylene resin is engineered for heavy‑wall large‑size injection and extrusion forming processes. Featuring a melt‑flow rate of 2.1, K8003 combines favorable low‑temperature impact resistance, high melt strength and reliable processing stability. It is well‑suited for heavy‑wall industrial end‑products with stringent toughness and anti‑impact requirements, including plastic pallets, turnover crates, hollow sheets and battery housings.
