Recently, the high-performance polypropylene HC9012D developed by Zhongke Refining & Chemicals was validated by a leading semiconductor materials company in the industry and put into mass production, marking the first time that Zhongke Refining & Chemicals’ high-performance polypropylene has entered the semiconductor manufacturing supply chain, thereby achieving import substitution. Polypropylene HC9012D features a high bending modulus, high surface hardness, high heat resistance, excellent resistance to surface scratching, good gloss, and good chemical resistance. It can be widely used in the manufacture of small household appliances, home goods, and children’s toys, as well as in the production of components for high-end precision instruments. Polypropylene HC9012D was developed by the R&D team of the Wenfu Innovation Studio at Sinopec Refining & Chemical. Focusing on the two key technical challenges of eliminating black spots and reducing metal ion content, the team optimized the production process and the impurity control system, thereby achieving international advanced levels in terms of product purity and resistance to vibration and drops – requirements that are essential for semiconductor precision processing. The successful delivery of this product is of strategic significance for ensuring the security of the industrial chain and enhancing the ability to innovate in high-end materials.
