Excellent weather resistance, UV, O2, O3, salt spray, etc.;

Low surface energy, excellent hydrophobicity and hydrophobic migration;

Excellent insulating properties, stable dielectric properties in a wide temperature and frequency range. Arc resistance and leakage resistance are very good;

It has good high temperature resistance and can be used continuously at 180-200℃. Although the strength of silicone rubber at room temperature is only half of that of natural rubber or some synthetic rubbers, it can still maintain a certain degree of flexibility, resilience and surface hardness in a high temperature environment above 200 °C, and has no obvious mechanical properties. Variety;

Good elasticity, good low temperature flexibility, can be used at -50 ℃. The glass transition temperature of silicone rubber is generally -70~-50℃, and the special formula can reach -100℃, indicating its excellent low temperature performance. This is of great significance to the lines used in the aviation and aerospace industries.

Good flame retardant performance, almost no toxic and harmful gases are released when burning;

It can be made into a transparent product, and defects such as air bubbles or impurities can be easily detected by visual inspection.

Compared with general-purpose rubber, silicone rubber has relatively simple compounding components for all three types of silicone rubber, as is thermal vulcanization type. In addition to raw rubber, the compounding agents mainly include reinforcing agents, vulcanizing agents and some special additives. Generally, only 5 to 6 components are needed to form a practical formula.
