PP Homopolymer for Injection Molding
This high‑performance homopolymer polypropylene raw material is engineered for general‑purpose injection‑molding applications. Boasting a melt‑flow rate of 12, HP500N exhibits high rigidity, superior surface gloss and consistent processing stability, while meeting food‑contact compliance requirements. It serves as an ideal resin for end‑products demanding outstanding stiffness and surface finish, including food containers, household articles, plastic toys and packaging housings.
