SiTPV market space is huge, but the number of domestic manufacturers is very small

Silicone thermoplastic vulcanizate (SiTPV) uses fully vulcanized silicone rubber particles as the dispersed phase and thermoplastic elastomer as the continuous phase. It uses dynamic vulcanization and cross-linking technology to evenly disperse the silicone rubber particles in the thermoplastic elastomer. A polymer material. SiTPV is a type of TPV (thermoplastic vulcanized rubber), and its performance is much higher than ordinary TPV.

SiTPV has a special island structure and has the advantages of smooth surface, good elasticity, wear resistance, high and low temperature resistance, UV resistance, chemical corrosion resistance, oil resistance, hydrolysis resistance, etc.; no by-products and volatiles are emitted during the SiTPV manufacturing process, and no additives are needed Plasticizers can be recycled and reused, with outstanding advantages in safety and environmental protection; SiTPV is easy to process and can be processed by injection molding, extrusion, etc. without post-processing, with high production efficiency and low overall cost. SiTPV can be widely used in consumer electronics, automobiles, medical, construction, sports and leisure and other industries.

Wearable devices are one of the important application areas of SiTPV. In addition to the functions of wearable devices, since the covering shell is in direct contact with human skin, the comfort, safety, aesthetics, and durability of the material are also of great concern. In addition, the material must also be lightweight and shock-absorbing. , waterproof and other functions to protect wearable devices. SiTPV has outstanding competitive advantages as a covering material for wearable devices and has been widely used in products of many brands such as Huawei and Xiaomi. In 2021, global wearable device shipments will continue to grow rapidly, with annual shipments exceeding 540 million units, which provides sufficient space for the development of the SiTPV market.

According to the “2022-2026 Silicone Thermoplastic Vulcanizate (SiTPV) Industry In-depth Market Research and Investment Strategy Suggestions Report” released by the Industrial Research Center shows that SiTPV is a new material developed by Dow Corning in the United States and has a number of patented technologies. my country is a major consumer electronics production country, with large shipments of wearable devices and other products, and strong demand for SiTPV. Therefore, there is an urgent need for independent research and development of SiTPV in my country. The government has introduced relevant policies to encourage and support the development of the SiTPV industry.

In October 2017, the Ministry of Industry and Information Technology issued the “Guidelines for the Development of Key Common Technologies in the Industry (2017)”, in which the preparation and application technology of high body-compatible silicone thermoplastic vulcanizate (SiTPV) was included, and it was proposed to develop SiTPV dynamic vulcanization reaction blending technology , SiTPV application technology in wearable devices, SiTPV application technology to replace traditional silicone rubber. In the second half of 2020, Chengdu Silico Technology Co., Ltd. independently developed and produced SiTPV materials.

Industry analysts said that overall, SiTPV has the advantages of both rubber and plastic, with excellent physical and mechanical properties and good processability. , with obvious green and environmental protection advantages and low overall cost, it is a category with excellent performance among TPV products and can be used in a wide range of applications, especially in the field of wearable devices. Due to its excellent comfort, safety and other properties, it has a broad market space. At present, the number of SiTPV manufacturing companies in my country is very small, and capable companies can enter this field.
