1、Technical barriers to：

Technical formula is the core of polymer materials and catalyst and purifier products manufacturing industry. In the formulation design, slight changes in the variety or quantity of raw materials and modified auxilaries will cause great fluctuations in product performance indicators. At present, the high performance professional product formula is mastered by the leading enterprises in each subdivision field, the consistency of product performance and quality is also largely affected by the core production process and application technology.

The research and development of a polymer material and catalyst and purifying agent product involves many fields and many technical links. It is very difficult in product formulation, reaction mechanism and other aspects, and has strict requirements on process control and process precision, as well as very high requirements on preparation technology and equipment. Leading enterprises in various fields are highly confidential about their production formula, production process and production equipment, while new enterprises usually lack technical accumulation, and it is difficult to have the corresponding technical level and research and development ability in a short time.

At the same time, polymer materials, catalysts and purification agent products are updated quickly, corresponding to the downstream customers for products with continuous performance optimization needs. In order to better adapt to market changes and meet market demands, enterprises need to have excellent technology research and development capabilities, teams and corresponding technical reserves, and constantly optimize and innovate the product formula, production process, control system and so on.

2、Barriers to talent：

Polymer material and catalyst and purifying agent industry with technology-intensive industry characteristics, excellent polymer materials and catalyst enterprises need a lot of polymer materials and catalysis technology product development and application technology development experience of excellent research and development personnel, to occupy the leading position in the increasingly fierce market competition. On the other hand, at the present stage of the development of related industries in China, relevant professional and technical talents are still scarce resources. In the face of the continuous and rapid development of various technologies such as high efficiency, compound and environmental protection in the polymer materials and catalyst industry, sophisticated and reasonable talent echelon and talent reserve constitute the talent barrier to enter the industry.

3、Capital barriers：

High polymer materials, catalyst and purifier products involved in the production process and preparation equipment requirements are relatively high, coupled with its significant economies of scale benefits, leading to a large investment in the early stage of research and development. The price of raw materials in the process of enterprise operation, affected by various complex factors such as macro economy, crude oil price, will show the characteristics of periodic fluctuations. The downstream industries of polymer materials are mostly mass consumer goods industries. Influenced by various complex factors such as macro economy, consumer psychology and technological progress, the prosperity degree of related industries also presents the characteristics of periodic fluctuations. Desulfurization catalysts, special catalytic materials and catalysts in energy purification products are supplied in large quantities in a single order, which generally adopts order-type production with a long production cycle and a large amount of capital occupied by inventory. Therefore, enterprises also need a certain scale of liquidity to cope with the risk of raw material prices and cyclical fluctuations in downstream industries.

4、Barriers to the customer：

Some downstream industries of polymer materials, such as automobile industry, electronic and electrical appliances, construction engineering, medical and health care, textile, rail transit, etc., have high requirements for product quality and safety. At the same time, the bidding conditions of catalysis and purification industry customers are relatively high, requiring years of good brand image, business performance, product quality assurance and perfect after-sales service network. Therefore, it is difficult for new entrants to establish perfect market channels and enter the bidding market smoothly in a short time.

These companies within the industry on the quality of the raw material identity is often established on the basis of investigation and business cooperation for a long time, usually by long-term, strict procedures to review before choosing scale strength strong, high technology level, product quality and stable business cooperation, on the strength of the supplier, brand, technology, service, team such as comprehensive quality requirement is very high, And once these enterprises choose the supplier, they will not change easily, and the business cooperation is relatively stable and long-term. For new entrants to the industry, the customer loyalty and brand effect formed based on long-term cooperation are the big barriers for them to enter the industry.
