Phenyl silicone rubber has broad application prospects and local enterprises’ production technology needs to be improved

The full name of phenyl silicone rubber is methylphenylvinyl silicone rubber, which refers to a high molecular weight linear polysiloxane containing phenylsiloxane or methylphenylsiloxane segments in the main chain. According to the different phenyl content, phenyl silicone rubber can be divided into three types: high phenyl silicone rubber, medium phenyl silicone rubber and low phenyl silicone rubber. The phenyl content in high phenyl silicone rubber is more than 30.0%. Phenyl silicone rubber has the advantages of low temperature resistance, aging resistance, radiation resistance, and a wide operating temperature range. It can be used as an elastomer raw material and is widely used in aerospace, medical and health and other fields.

The phenyl silicone rubber industry has high technical barriers. There are processing difficulties in high phenyl and medium phenyl silicone rubber. The development of the industry is relatively slow. At present, low phenyl silicone rubber is the mainstream product in the Chinese market. Low phenyl silicone rubber usually uses methylsiloxane ring and phenylsiloxane ring as raw materials. Under certain temperature conditions, the dehydrated raw materials are mixed, then catalysts and end-capping agents are added, and after full reaction Preparation of phenyl silicone rubber. The production of phenyl silicone rubber in my country is mainly based on the intermittent method, and there are no enterprises with continuous production capabilities.

According to the “2022-2027 China Phenyl Silicone Rubber Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , Phenyl silicone rubber is a high-temperature vulcanized silicone rubber subdivision product. High-temperature vulcanized silicone rubber is widely used in wires and cables, electronic components and other fields. Driven by market demand, its production continues to increase. In 2021, my country’s high-temperature vulcanized silicone rubber output reached 879,000 tons, a year-on-year increase of 11.7%. As the development of the high-temperature vulcanized silicone rubber industry continues to accelerate, the market space for phenyl silicone rubber continues to expand.

Phenyl silicone rubber has the characteristics of radiation resistance and low temperature resistance, and is in high demand in aerospace, medical and health, wire and cable and other fields. In the aerospace field, phenyl silicone rubber can be used to produce seals, including sealing rings, gaskets, etc.; in the medical and health field, phenyl silicone rubber can be used to produce medical elastomer products, including oxygen masks, medical gloves, and tracheal tubes. wait.

The main phenyl silicone rubber manufacturers in my country include Jiangxi Chenguang New Materials Co., Ltd., Anhui Mingyi Silicon Industry Co., Ltd., Chengdu Senfa Rubber and Plastic Co., Ltd., Sichuan Taiyi High-tech Materials Co., Ltd., etc. It is expected that in the future, driven by technological innovation, the production cost of phenyl silicone rubber will be reduced, which will attract more companies to lay out the medium-phenyl and high-phenyl silicone rubber tracks.

Industry analysts said that phenyl silicone rubber is widely used in many fields. Driven by market demand, the industry has broad prospects for development. Medium phenyl and high phenyl silicone rubber, as subdivided products of phenyl silicone rubber, have problems such as poor physical and mechanical properties, and have a relatively small market share. With the continuous breakthroughs in R&D and production technology of local enterprises and scientific research institutions, their market size will increase in the future. It is expected to expand further.
