Silicone rubber is renowned for its exceptional heat resistance, outstanding low-temperature flexibility, ozone resistance, atmospheric aging resistance, and excellent electrical insulation properties. Its low water absorption allows for long-term storage in humid environments, making it ideal for applications across aerospace, military, electrical, and medical sectors. However, due to its helical molecular structure and high softness, silicone rubber has weak intermolecular forces, making it difficult to crystallize. The tensile strength of vulcanized silicone rubber is typically not more than 0.34 MPa, which significantly limits its applications.

To enhance the physical and mechanical properties of silicone rubber, the addition of reinforcing fillers is essential. Only with the incorporation of reinforcing materials does silicone rubber gain practical value. To reduce the production costs of silicone rubber products, the market has begun to partially replace fumed silica with ultrafine precipitated silica, leading to significant breakthroughs in application research. Consequently, the demand for ultrafine precipitated silica specifically designed for silicone rubber has seen a rapid increase.

Ultrafine precipitated silica is a cost-effective alternative to fumed silica, offering improved processing and performance characteristics. It is engineered to provide superior reinforcement, enhancing the tear strength, tensile properties, and overall durability of silicone rubber compounds. This advanced material is crucial for manufacturers looking to balance performance with cost efficiency in their silicone rubber products.

Incorporating ultrafine precipitated silica into silicone rubber formulations not only improves the mechanical properties but also contributes to better processing, reduced shrinkage, and improved dimensional stability. It is a key component in the production of high-quality silicone rubber goods that meet the stringent requirements of various industries.

Q&A: 

The method of adding silica in silicone rubber industry:

Silicon dioxide in silicone rubber is usually added in the form of precipitation or drying, among which precipitation method is currently the most widely used addition method. The precipitation method can control the particle size and distribution of silica, thereby achieving precise control of the physical and rheological properties of silicone rubber.

In the preparation of silicone rubber, proper addition of silicon dioxide can improve the stability and anti-aging properties of silicone rubber, so that silicone rubber can play the best performance in various extreme environments.
