PetroChina K8003 is a specialized high-impact polypropylene block copolymer resin (PP-B) from PetroChina, with mainstream supply channels covering Dushanzi and Guangdong branches of the company. It is purpose-built for injection molding applications requiring a harmonious balance of structural firmness and high-level impact resistance. The product features a medium-to-low melt flow rate of 2.5–3.5 g/10min under the standard testing condition of 230°C and 2.16kg load. Its fixed core mechanical specifications include a tensile yield strength of ~26 MPa, a flexural modulus of ~1300 MPa, and an Izod impact strength of ~70 J/m.
Injection molding products crafted from this PP material possess exceptional impact resistance and sound rigidity, supporting the production of heavy-load components and reusable turnover boxes.
