Phenyl silicone rubber is a type of synthetic rubber with excellent properties, composed of monomers such as styrene and dimethylsilane. This rubber boasts outstanding high-temperature resistance, primarily due to the presence of siloxane groups. Siloxane groups exhibit high chemical inertness and thermal stability, enabling the rubber to maintain good elasticity and physical properties at high temperatures.
Phenyl silicone rubber has a density ranging from 1.1 to 1.3 g/cm³, a hardness of 30 to 80 Shore A, a tensile strength of 5 to 12 MPa, and an elongation at break of 150% to 500%. Additionally, its electrical insulation strength is between 20 and 40 kV/mm, making it widely used in the power and electronic industries.
Based on the phenyl content, phenyl silicone rubber can be classified into low-phenyl, medium-phenyl, and high-phenyl silicone rubbers. Low-phenyl silicone rubber exhibits good low-temperature resistance and high damping characteristics, while medium-phenyl silicone rubber has ablation resistance and flame retardancy. High-phenyl silicone rubber, on the other hand, demonstrates excellent radiation resistance.
In terms of applications, phenyl silicone rubber is widely used in automotive manufacturing, aerospace, electronics, and medical devices. It can be used to manufacture automotive sealing materials, rubber tubes, and rubber parts, as well as high-temperature seals, hydraulic seals, and rubber tubes in the aerospace industry. Furthermore, it is utilized in the manufacture of high-temperature cables, cable protection tubes, and electrical insulation components in the electronics industry, as well as seals and piping in medical devices.
