Competition pattern and main barriers in PVC additives industries

1. Industry competition pattern and concentration analysis

After years of development, China's PVC processing additives and impact modifier industry has formed a certain scale, there are many production enterprises, the degree of marketization is higher, and according to the product formed a different marketization characteristics and competition pattern.

(1) Low-end products with low entry threshold and mature production process technology or relatively large pollution: at present, there are many domestic manufacturers, fierce competition and high degree of marketization, such as CPE and general processing AIDS.

(2) Medium and high-end products with a certain threshold of entry and high processing technology requirements or high environmental friendliness and good performance indicators: at present, domestic ACR products have reached the international advanced level, and the production is mainly produced by several leading manufacturers; MBS products have high requirements for production process and technology, and only a few existing companies can fully meet the standards of domestic products.

2.The main barriers to the industry

(1) Technical and talent barriers

The technological development of PVC additives industry mainly depends on the continuous summary and accumulation of experience by manufacturers in the production process, improving the production process, improving product performance and production efficiency. As a typical chemical industry, the improvement of technical experience is not only generated in the laboratory stage, but more importantly, the empirical control of the process and flow in the process of large-scale production, which is usually in the form of non-patented technology.

The downstream PVC processing industry of PVC auxiliaries is a non-standardized production industry, and there are different requirements for the performance of PVC auxiliaries according to the different PVC products produced. This determines that the production of PVC auxiliaries also has non-standardized characteristics to a certain extent.

PVC processing industry procurement of PVC additives often first ask for a certain sample for trial, and then decide whether to purchase or not according to the trial results and the specific purchase model and purchase quantity. PVC auxiliary production enterprises with technical advantages and rich production experience can configure personalized ingredients according to the feedback results of PVC processing enterprises in the production trial, and there is no technology accumulation, but simply imitate the production of PVC auxiliary enterprises can not achieve the above positive interaction with downstream enterprises.

The production process of PVC additives involves the storage, transportation and use of dangerous chemicals, especially MBS impact modifiers in the production process, easy to cause fire danger, only through strict process control, in order to minimize this risk, and this strict process control and standardized reasonable operating procedures. It is necessary to form repeated technical accumulation and correction in the long-term production process of PVC auxiliaries.

(2) Market first entry barriers and customer barriers

PVC additives are auxiliary raw materials in the processing of PVC products, and the characteristics of auxiliary raw materials are that although the addition is less, it has an important impact on the performance of the overall product. Once there is a problem with the performance of the additives, the whole batch of PVC products will have quality problems and even be scrapped, resulting in greater economic losses. Therefore, the performance stability and quality reliability of PVC products are the first factors considered by users. Users have strict procedures for the trial of products, and will not easily change after selecting a supplier.
