Main Categories of Sinopec PP Resin

China Petroleum & Chemical Corporation classifies its polypropylene (PP) products into several major categories based on polymerization method and application direction. Each category includes multiple grades designed to meet different processing technologies and end-use requirements.

Homopolymer Polypropylene (PP-H). Homopolymer PP features high crystallinity and excellent rigidity. It offers outstanding mechanical strength and dimensional stability, making it suitable for injection molding, extrusion, fiber production, and general-purpose applications.
Random Copolymer Polypropylene (PP-R). Random copolymer PP provides improved impact performance and higher transparency compared to homopolymer grades. It is ideal for thin-wall products, transparent containers, medical applications, and pipe systems requiring enhanced clarity and toughness.
Block Copolymer Polypropylene (PP-B). Block copolymer PP combines high impact strength with good stiffness. It delivers superior low-temperature resistance and durability, making it particularly suitable for automotive components, home appliance housings, and other high-performance engineering applications.
