Room temperature vulcanized silicone rubber (RTV) has a wide range of applications and the competitiveness of local companies is expected to accelerate.

Silicone rubber is a linear, high molecular weight polysiloxane. According to different vulcanization methods, silicone rubber can be divided into two categories: high-temperature vulcanization (heat vulcanization) silicone rubber and room temperature vulcanization (including low-temperature vulcanization) silicone rubber. Room temperature vulcanized silicone rubber, also known as RTV silicone rubber and silicone room temperature rubber, refers to a linear polymer polysiloxane with low molecular weight produced through room temperature vulcanization. The main categories include single-component room temperature vulcanized silicone rubber, Two-component condensation type room temperature vulcanization silicone rubber, two-component addition type room temperature vulcanization silicone rubber, etc.

Room temperature vulcanized silicone rubber can be cured directly at room temperature without heating and pressure. It has excellent properties such as easy use, non-corrosive, non-polluting, good adhesion, good UV resistance, and good heat resistance. It can be used as Sealing, bonding and shock-proof materials are used in building curtain walls, insulating glass, decoration, electronic appliances, home appliances, automobiles, optical instruments, energy and electricity, food and medicine and other fields.

Specifically, construction is the largest application field of room temperature vulcanized silicone rubber. In this field, room temperature vulcanized silicone rubber is mainly used as a sealant in building curtain walls, house construction, and prefabricated building sealing scenarios. With the continuous green development trend of the domestic construction industry With the deepening and rapid development of the prefabricated construction industry, its market demand continues to increase; energy and electricity are a new application field with rapid growth for room temperature vulcanized silicone rubber. In this field, room temperature vulcanized silicone rubber is mainly used as component packaging materials and photovoltaic module bonding. Agents are used in solar module preparation scenarios. As the prosperity of the domestic photovoltaic power generation industry continues to rise, its penetration rate in the photovoltaic market is accelerating.

Driven by the rapid development of downstream application fields, my country’s demand for room temperature vulcanized silicone rubber continues to increase, which in turn drives the continuous improvement of production capacity. According to the“Room Temperature Vulcanized Silicone Rubber (RTV) Industry Market In-depth Research and Investment Prospects Forecast Analysis Report 2023-2028” released by the Industrial Research Center shows that my country’s room temperature vulcanization silicone rubber production capacity will be approximately 2.841 million tons in 2022, a year-on-year increase of 10.5%.

The companies that are laying out my country’s room temperature vulcanized silicone rubber market mainly include leading international chemical companies such as Momentive Chemical of the United States, Wacker Chemical of Germany, DowDuPont of the United States, Shin-Etsu Chemical of Japan, Henkel Group of Germany, Sika Group of Switzerland, as well as Silicon Bao Technology, among others. Local enterprises such as Jiang Silicone Chemical, Baiyun Chemical, Jitai Chemical, Silande High-Tech, Ouliya Chemical, Yongan Rubber Industry and so on.

Industry analysts said that international companies currently dominate the mid-to-high-end market for room temperature vulcanized silicone rubber in my country, while local companies are mainly concentrated in There is huge room for domestic substitution in the low-end market and the mid- to high-end market. However, after continuous development in recent years, Chinese companies have the ability to independently design automated production lines for room temperature vulcanized silicone rubber, and the localization process of related raw materials, additives, etc. is accelerating. The domestic room temperature vulcanized silicone rubber industry is in a stage of rapid development. In the future, localization Enterprises are expected to accelerate their efforts to catch up with leading international enterprises and gradually narrow the gap with them in technology, scale, brand building, and product quality.
