Highly transparent polypropylene has excellent comprehensive properties and the industry structure needs to be upgraded

Highly transparent polypropylene is a type of high-end polypropylene product. Polypropylene (PP) is a colorless, translucent, general-purpose thermoplastic with excellent properties. The reason for its opacity is mainly due to the law of crystallization. As application fields continue to expand, polypropylene segmented products continue to increase, high-end polypropylene has better performance, and demand is growing faster. Highly transparent polypropylene can meet the manufacturing needs of various transparent products, and has large market development space.

There are three main methods for producing highly transparent polypropylene, namely using metallocene catalysts, adding nucleating agents (transparent modifiers), and using Z-N catalyst random copolymerization. During the production process, the quality of catalysts and nucleating agents directly affects the transparency performance of highly transparent polypropylene.

According to the “China Highly Transparent Polypropylene Industry Market In-depth Research and Development Prospects Forecast Report 2023-2028” released by the Industrial Research Center , the highly transparent polypropylene obtained by modification inherits the excellent stiffness, toughness, chemical corrosion resistance, light weight, and easy processing of traditional polypropylene. It also has the advantages of high transparency, high surface gloss, and high heat distortion temperature. , can be widely used in household utensils, food and beverage containers, cosmetic packaging, pharmaceutical packaging, medical equipment, home appliances, automotive interiors, stationery, toys, sports equipment and other manufacturing fields.

Compared with other common transparent materials such as PC (polycarbonate), PVC (polyvinyl chloride), PS (polystyrene), PET (polyethylene terephthalate) and other common transparent materials, highly transparent polypropylene has a better transparency and surface The glossiness is close to that of the product, and the heat distortion temperature is higher. It also has the advantages of light weight, simple process, recyclability, etc., and has strong market competitiveness.

From 2015 to 2022, the compound annual growth rate of my country’s highly transparent polypropylene market is 8.1%. Driven by demand, the output of highly transparent polypropylene in my country has increased rapidly, becoming one of the fastest growing product types in the polypropylene industry.

Overseas high-transparent polypropylene manufacturers mainly include ExxonMobil, SK Group, Mitsui Chemicals, Dow Chemical, BASF, Borealis, LyondellBasell, Japan Polypropylene Co., Ltd., etc. The main manufacturers of highly transparent polypropylene in my country include Yanshan Petrochemical, Qilu Petrochemical, Shanghai Petrochemical, Maoming Petrochemical, Zhongyuan Petrochemical, Lanzhou Petrochemical, Dushanzi Petrochemical, Zhenhai Refining and Chemical, Xuzhou Haitian, North Huajin, Shenhua Yulin, etc.

Industry analysts said that many companies in our country mainly produce low-end transparent polypropylene, which is used in medical devices and other fields. High-end high-transparent polypropylene manufacturers account for a small proportion. In order to avoid cross-infection and improve medical safety, my country’s market demand for disposable medical devices such as disposable syringes and disposable infusion bags continues to grow. In the context of the aging of the population and the increasing national health awareness, my country’s consumption of disposable medical devices is large, and the development prospects of highly transparent polypropylene are broad. Therefore, the industry structure needs to be continuously upgraded.
