PP Impact Copolymer for Injection Molding
This low‑flow impact‑copolymer polypropylene raw material is specially designed for large‑size injection and extrusion processing. 2500HW features a melt flow rate of around 2.26, delivering outstanding low‑temperature impact resistance, high melt strength and stable processing performance. It is an ideal choice for heavy‑wall industrial products requiring high toughness and melt strength, such as plastic pallets, battery housings, crates and hollow sheets.
