The Vital Role of Hydrophobic Silica in Elastomers: Case Studies of HTV Silicone Rubber and LSR
Introduction
In modern industry, elastomer materials are widely used in various fields due to their excellent flexibility and durability. Among them, high-temperature vulcanized silicone rubber (HTV) and liquid silicone rubber (LSR) are highly favored for their outstanding properties. Hydrophobic silica, as an important additive, plays a key role in these two types of silicone rubbers, significantly enhancing the performance and application range of the materials.
Characteristics of Hydrophobic Silica
Hydrophobic silica is a special treated form of silicon dioxide, with its surface covered by hydrophobic groups. This structure gives it excellent dispersion and compatibility in elastomers, effectively improving the mechanical properties, processing properties, and durability of the materials. In addition, hydrophobic silica also has a high specific surface area and good adsorption properties, further enhancing its application effect in elastomers.
Application of Hydrophobic Silica in HTV Silicone Rubber
In HTV silicone rubber, the addition of hydrophobic silica can significantly increase the mechanical strength and wear resistance of the material. Its high specific surface area and hydrophobic surface can form a good interaction with the silicone rubber matrix, enhancing the cohesion and tensile strength of the material. At the same time, hydrophobic silica can also improve the processing properties of HTV silicone rubber, making it more uniform and stable during mixing and vulcanization, thereby increasing production efficiency and product quality.
Application of Hydrophobic Silica in LSR
For LSR, the addition of hydrophobic silica can effectively improve its fluidity and demolding properties. Its hydrophobic surface can reduce the friction between LSR and the mold, making the material flow more smoothly during injection molding, thereby increasing production efficiency and the surface quality of the products. In addition, hydrophobic silica can also enhance the mechanical properties and durability of LSR, allowing it to maintain good performance under harsh conditions such as high temperature and high pressure.
