The market demand for polymerization inhibitors is vast and the industry needs to upgrade in the direction of greening and high-end in the future.

Polymerization inhibitor is an industrial additive used to prevent polymerization. Its principle of action is to react with chain free radicals through the polymerization inhibitor molecules to form non-free radical substances or low-activity free radicals, thereby achieving free radical polymerization. A process that completely terminates its purpose. There are many types of polymerization inhibitors. According to different raw materials, polymerization inhibitors can be divided into phenolic polymerization inhibitors, quinone polymerization inhibitors, inorganic compound polymerization inhibitors, aromatic nitro compound polymerization inhibitors, etc.; depending on the reaction temperature, polymerization inhibitors Agents can be divided into active fixed polymerization inhibitors, heat-sensitive polymerization inhibitors, dual polymerization inhibitors, etc.

After continuous technological breakthroughs and the emergence of new materials in recent years, my country’s polymerization inhibitor product categories have been continuously enriched, and the market update speed has been accelerated. Starting from the highly toxic first-generation polymerization inhibitors DNP and DNPC, domestic polymerization inhibitors have experienced approximately four generations of product replacement. The polymerization inhibitors currently occupying the majority of the market mainly include hydroquinone and tert-butyl catechol. , DNBP and other phenols, diethylhydroxylamine and other amine polymerization inhibitors.

According to the “Polymerization Inhibitor Industry Market In-depth Research and Investment Prospect Forecast Analysis Report 2023-2028” released by the Industrial Research Center, As an important chemical additive, polymerization inhibitors are mainly used in the processing, refining, and storage of olefin monomers and derivatives such as styrene, acrylic acid, acrylonitrile, butadiene, acrylates, and methacrylates. , which plays the role of increasing production stability and preventing polymerization reaction from proceeding. Currently, as the application fields of olefin monomers and derivatives continue to expand and production capacity continues to increase, the market demand for polymerization inhibitors, as key additives required for their processing, storage and transportation, continues to increase.

Take butadiene, acrylic acid, and styrene as examples. All three are important chemical raw materials and are widely used in synthetic rubber, resin and other scenarios. The terminal fields include building materials, coatings, dyes, automobiles, machinery, home appliances, etc. In 2022, domestic butadiene production capacity will be 5.897 million tons, acrylic acid production capacity will exceed 3.600 million tons, and styrene production capacity will be approximately 14.866 million tons. Against this background, the domestic polymerization inhibitor market continues to expand, and the industry shows good development prospects.

my country is the main producer of polymerization inhibitors in the world. The domestic polymerization inhibitor companies mainly include Jiuxin Industrial, Liansheng Technology, Jiufenglong Chemical, Zhuojin Chemical, Zhenxing Chemical, Taidun Chemical, Tongcheng New Materials, Purity Chemical, etc. There are a large number of enterprises, but most of them are small and medium-sized enterprises, and the industry concentration is low. In the future, local companies will need to accelerate their deployment in the high-end, green, and environmentally friendly polymerization inhibitor market to promote continuous upgrading of the industry.

Industry analysts said that polymerization inhibitors are an important type of chemical additives that are used in many applications such as butadiene, acrylic acid, styrene, etc. All kinds of chemical materials are used in the production, processing, storage and transportation processes, and the market demand is huge. At the same time, after recent years of development, my country’s polymerization inhibitor product upgrades have been accelerating. At present, the industry is continuously upgrading in the direction of green, environmental protection, high performance, and high-end. However, most local companies have low technical levels and weak innovation capabilities. of small and medium-sized enterprises. Therefore, local enterprises will need to accelerate their transformation and upgrading in the future.
