On August 27, 2019, the polypropylene plant of ZGSH's synthetic resin department successfully produced metallocene polypropylene products. According to the company's production schedule, this time, it will produce 1,800 tons of metallocene polypropylene products. This is also the third successful mass production of metallocene polypropylene products in the polypropylene plant of ZGSH Synthetic Resin Department following May and August this year. At present, only a few large international petrochemical giants such as ExxonMobil have truly realized the commercial production of metallocene polypropylene products. There is no successful precedent for Chinese companies. ZGSH has successfully filled the gap in China's production.
Compared with polypropylene polymerized by traditional catalysts, metallocene polypropylene has ultra-high transparency and gloss, good temperature resistance, and low precipitation. It is especially suitable for food, medicine and cosmetics that require strict transparency and hygiene. Packaging can also be used as a substitute for PS, ABS, PET and other engineering plastics.
Metallocene polypropylene provides super-transparent properties for cosmetic packaging. With the gradual improvement of people's living standards in recent years, the demand for metallocene polypropylene in the Chinese market is increasing. Therefore, it is imperative to improve the production level of domestic metallocene polypropylene. Compared with ordinary transparent polypropylene, metallocene catalyst technology can push the transparency of polypropylene to a new level. The haze of 1mm plate can be reduced from 9 to 3-4. In addition, the metallocene super transparent polypropylene can still maintain good transparency in thick parts, so it gives more space in product design and application.
Ultra-high transparent metallocene polypropylene also has the characteristics of high gloss, good temperature resistance, and low precipitation (only 20%-25% of conventional transparent polypropylene). Among many Chinese companies, ZGSH is the first company in China to overcome the difficulties of continuous production of metallocene polypropylene, and has realized China's first industrial production of metallocene ultra-high transparent polypropylene special materials. Its product performance is stable and can reach the level of similar imported products, breaking the monopoly of similar foreign products.
Ultra-high transparent metallocene polypropylene is an ultra-high transparent random copolymer polypropylene with high gloss, excellent transparency, low precipitation and good sensory properties. It is suitable for injection molding and blow molding. In the field of cosmetics, super transparent PP using metallocene catalysis technology can achieve glass-like transparency.
Most of the popular ampoule essence packaging nowadays uses injection molding technology, and the injection molding temperature of ultra-high transparent metallocene polypropylene can be as low as 190℃, which is more conducive to energy saving and emission reduction. Integration of production, marketing, research and application, and deployment of high-end customized production As a leading company in the R&D and production of new materials in China, ZGSh regards the development of metallocene polypropylene as an important strategy for high-end and customized products. The company has developed a series of product portfolios around metallocene ultra-permeable polypropylene, such as high-performance products with radiation resistance, low crystal point, and low heat sealing, aiming at the growing market in healthcare, electronic packaging, building materials, and cosmetic packaging. High-end applications.
