Thermoplastic vulcanizate (TPV) has broad application prospects and local companies are actively catching up with international companies.

Thermoplastic vulcanized rubber, referred to as TPV, also known as polyolefin alloy thermoplastic elastomer, is a polymer elastomer material composed of highly vulcanized ethylene propylene diene rubber (EPDM) particles dispersed in a continuous polypropylene (PP) phase. The main production methods include dynamic There are three categories: vulcanization method, solution blending method, and latex blending method. Among them, dynamic vulcanization method is the current mainstream production method of thermoplastic vulcanized rubber.

Thermoplastic vulcanized rubber combines the excellent resilience of traditional elastomers with the special ease of recycling of thermoplastics. It is a new type of polymer material with excellent comprehensive properties. It is mainly characterized by green environmental protection, good sealing, good processing performance, and strong deformation resistance. , good aging resistance, wide application range and recyclability, etc.

At present, thermoplastic vulcanized rubber has been widely used in home appliances, electronics, medical, photovoltaic, automobile, construction, rail transit and other fields. Specifically, in the automotive field, TPV is mainly used in the production of automotive seals/conditions, high-pressure ignitions, buffers, mud inlet plates and other parts; in the construction field, TPV is mainly used in building materials such as pipe seals and door and window seals. Production scenarios; in the medical field, TPV is mainly used in the production of medical rubber stoppers; in the photovoltaic field, TPV is mainly used in the production of photovoltaic splicing plug-ins.

As a new type of thermoplastic elastomer, thermoplastic vulcanized rubber has broad application prospects in the market. In the future, as the trend of TPV replacing traditional thermoplastic PVC (polyvinyl chloride) continues to rise, its market size will continue to expand. According to the “China Thermoplastic Vulcanized Rubber (TPV) Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center It is estimated that by 2024, my country’s thermoplastic vulcanized rubber market is expected to reach 3 billion yuan.

Driven by the rapid development of the national economy, my country has become the world’s largest consumer of thermoplastic vulcanized rubber, and demand has shown a continuous upgrading trend from low-end to high-end. However, due to technical limitations, domestic demand for high-end TPV still relies on imports. Leading international companies such as Mitsui of Japan, ExxonMobil Chemical of the United States, and Teknor Apex Company of the United States dominate the domestic market.

In recent years, Chinese TPV companies have been continuously making breakthroughs in key technologies and accelerating the pace of catching up with leading foreign companies. For example, in 2023, Dawn Co., Ltd. broke the international technology monopoly and developed the first domestic TPV production line with independent intellectual property rights. In the future, as domestic companies continue to increase their efforts in technology research and development, the pace of domestic substitution in my country’s high-end TPV market is expected to continue to accelerate. Optopolymer, Xinya Polymer, Baiente New Materials, Meite Polymer, Jieke Polymer, Jutemann Polymer, and CGN Delta Group are domestic TPV manufacturers.

Industry analysts said that thermoplastic vulcanized rubber is a new type of polymer material with excellent performance and broad application prospects. With its superior performance It has been continuously highlighted that TPV has become a general trend in replacing PVC in many fields, and the market size is expected to continue to expand in the future. At present, my country’s TPV companies are actively developing advanced technologies and accelerating the pace of catching up with leading foreign companies. In the future, they are expected to accelerate the realization of domestic substitution in the high-end market.
