There are many problems in the engineering plastics industry, which directly restrict the industrialization, planning, marketization and branding of engineering plastics. First, the industrialization process is slow, which is closely related to the traditional pattern of separation of production and research and the lack of capital investment. Second, there is a severe lack of investment in scientific research, and independent technology cannot be developed. Third, the existing resin and modified production equipment have small planning, backward technology, few varieties and trademarks, and low level; It is difficult to realize the planned economy. At present, the operating rate of engineering plastics production equipment is very low. Engineering plastics cannot compete with imported products in terms of product performance or price. Fourth, the product varieties are relatively concentrated. Focusing on this aspect, the domestic trademark of basic resin is few and the import volume is large, which restricts the development of engineering plastics in China to a great extent and makes domestic enterprises fall into the strange circle of price competition of medium and low-grade materials.

On the other hand, with the economic trend and China' s accession to the WTO, China' s economy and industry are facing both opportunities and challenges. The development of engineering plastics industry is a bit of a "domestic problem and foreign invasion". On the one hand, foreign companies use various access standards to set up market barriers, resulting in unfair competition, which has caused great pressure on Chinese enterprises still in the development stage, and put the materials and products at a disadvantage; On the other hand, the majority of small and medium-sized enterprises, the shopping malls are in disorder, lack of corresponding technical standards, and the products make up the numbers. These two factors have severely restricted the development of the industry. Seeking development is the only way for the development of engineering plastics industry, which requires enterprises to fulfill standards, cooperate and unite to enhance strength and the concept of industrial chain.
