With the rapid economic growth, China has become the world’s largest polypropylene (PP) market. According to the public data, there will be 9.51 million tons of new domestic PP capacity in 2019-2020, and it is estimated that the domestic PP capacity will reach 45 million tons by 2025. At present, the terminal demand growth of general material market can not keep up with the speed of new production capacity, and the domestic PP general material market has entered the era of overall surplus.
In contrast, domestic high-end PP special materials still rely heavily on imports. Driven by consumption upgrading, domestic demand for high-end PP continues to grow, and there is still a large gap between supply and demand. It is estimated that China’s PP import dependency will reach 19% in 2019. Therefore, high-end PP special materials with high added value and high import dependence have become a new growth point in the domestic market.

In order to solve the pain point of market demand, Jinmin new materials, together with Xiamen University and downstream customers, successfully developed a new functional environmental friendly flame retardant PP special material after more than one year through the coordination of industry, University, research and upstream and downstream industries. The product has passed UL (USA), SGS and other authoritative tests, all technical indicators meet the relevant standards, mechanical and mechanical properties are excellent, the fire-retardant level reaches UL94 V-0, and the performance is superior to similar products at home and abroad.
According to the research and Development Engineer of Jinmin new material, the research and development of this special material has achieved breakthroughs in three aspects: first, a reactive phosphorus nitrogen flame retardant has been developed, through in-situ grafting modification with PP, the dual effects of flame retardancy and compatibilization have been achieved; second, the synergistic flame retardancy, smoke suppression and improvement of carbon layer structure have been realized by using phosphorus nitrogen silicon internal hybrid technology, giving PP Flame Retardancy function; Third, independent R & D equipment, with in-situ reaction, uniform dispersion and other functions, with corresponding auxiliary machines, to achieve stable and efficient production.
The project’s patent licensing results support the engineer’s claim. At present, the project has been granted 6 national invention patents, 3 utility model patents and 1 design. The project has completed the whole process of “basic research, application development, patent protection, promotion and application”, which is of positive significance to promote the technical progress of high-end PP resin special materials in China and replace the import.

Technological breakthrough is more directly reflected in product performance. Jinmin new functional environmental friendly flame retardant PP special material overcomes the problems of poor low-temperature impact resistance, easy aging, flammability, large amount of molten drops and so on, and improves the flame retardant performance of the product. At the same time, through the aging resistance modification and crystal control of flame-retardant PP, the service life of flame-retardant PP material in long-term harsh environment is prolonged, the surface gloss of flame-retardant PP is improved, and the application field of flame-retardant PP products is expanded.
At present, Jinmin new functional environment-friendly flame-retardant PP special material has achieved mass production, providing services to nearly 100 customers in the automotive, electronic, electrical, kitchen and bathroom industries. In addition, Jinmin new material has developed anti-bacterial and flame-retardant PP intelligent toilet special material, low odor PP car material, functional enhanced PP irrigation equipment special material, low shrinkage modified PP and other products in response to the market demand of PP special material, which has been widely recognized by downstream customers.
