In the context of automobile lightweight development, long glass fiber reinforced PP (LGFPP) has broad application prospects

According to the different lengths of glass fiber fibers, glass fiber reinforced polypropylene can be divided into two categories: short glass fiber reinforced polypropylene (SGFPP) and long glass fiber reinforced polypropylene (LGFPP). Long glass fiber reinforced polypropylene refers to glass fiber reinforced polypropylene. Modified PP composite materials with a length of 10 to 25 mm are formed through injection molding and other processes to form a three-dimensional structure with a glass fiber length greater than 3.1 mm.

Long glass fiber reinforced PP has the characteristics of good dimensional stability, high impact strength, good creep resistance, and excellent fatigue resistance. It is widely used in automobiles, home appliances, communications, electronics, power tools, building materials and other fields. Long glass fiber reinforced PP products can reduce weight, reduce energy consumption, optimize assembly processes, etc. They are the preferred material for lightweight automobiles and can replace steel products, aluminum products, thermosetting composite materials, etc.

According to the “2022-2027 China Long Glass Fiber Reinforced PP (LGFPP) Industry Market In-depth Research and Development Prospects Forecast Report” shows that in 2021, the global long glass fiber reinforced PP market size will be approximately 13.45 billion yuan. Against the background of the development of automobile lightweighting and electronic miniaturization, long glass fiber reinforced PP has broad application prospects. It is expected that in 2026, the global long glass fiber reinforced PP market will be about 13.45 billion yuan. The fiber-reinforced PP market size will reach 21.50 billion yuan. In the global market, the long glass fiber reinforced PP market is mainly distributed in Europe, Asia-Pacific, North America and other regions. The main suppliers include Saudi Basic Industries Corporation, Japan’s Mitsui Chemicals, Polyone, South Korea’s Lotte Chemical, etc. The market concentration is high.

The length of glass fiber fiber is an important factor in determining the performance of glass fiber reinforced PP materials. Compared with short glass fiber reinforced PP, long glass fiber reinforced PP has certain advantages in strength, warpage, stiffness, fatigue resistance, dimensional stability, etc. . In recent years, with the development of lightweight vehicles, long glass fiber reinforced PP has attracted more and more attention from car companies, such as Chery, Dongfeng Fengshen, Qijun, BMW, etc. With the active layout of relevant companies, long glass fiber reinforced PP has been used in the rear of automobiles. It is increasingly used in automotive parts such as doors, door modules, bumper brackets, and sunroof frames.

In China, there are many long glass fiber reinforced PP suppliers, including Fujian Haiyuan, Shanghai Plite, Suzhou Antep, Shanghai Nayan New Materials, Trinseo, Kingfa Technology, Nanjing Julong and other companies, but overall , long glass fiber reinforced PP suppliers are mainly small and medium-sized enterprises. From the perspective of enterprise distribution, long glass fiber reinforced PP enterprises are mainly distributed in the Yangtze River Delta, Pearl River Delta and Bohai Rim regions.

Industry analysts said that long glass fiber reinforced PP has excellent performance and is an excellent substitute for metal materials and thermosetting materials. It is widely used in automobile lightweight applications. In the context of the development of quantification and electronic miniaturization, long glass fiber reinforced PP has broad application space. There are many long glass fiber reinforced PP manufacturers in my country, but the scale of the companies is generally small, and most of them have no advantages in international market competition. In the context of consumption upgrading, my country’s long glass fiber reinforced PP companies have large room for improvement.
