The main performance

1. High temperature performance. Although the strength of silicone rubber at room temperature is only half of that of natural rubber or synthetic rubber, it can still maintain a certain flexibility, toughness and surface hardness at a temperature above 200℃ under the environment, and its mechanical properties do not change significantly.

2. Under the glass transition temperature, the low temperature performance of silicone rubber is generally -70 ~ -50 ℃, specially prepared as -100 ℃, indicating that the low temperature performance of silicone rubber is good. This is of great significance to the space industry.

3, weather resistance silicone rubber on the si-o-si bond oxygen, ozone and uv very stable, in the absence of any additives, it has excellent weather resistance.

4. Electrical performance. The silicone rubber of the cable has excellent insulation performance, corona and arc resistance is also very good.

Physical and mechanical properties. The physical and mechanical properties of silicone rubber at room temperature are worse than that of ordinary rubber, but its physical and mechanical properties are better than those of ordinary rubber at 150℃ and 50℃.

6. Oil resistance and chemical reagent resistance. Ordinary silicone rubber has medium oil resistance and solvent resistance.

7. Gas transmission performance. At room temperature, the air permeability of silicone rubber to air, nitrogen, oxygen, carbon dioxide and other gases is 30-50 times that of natural rubber.

8. Physiological inertia. The silicone rubber of the cable is non-toxic, tasteless, tasteless, non-adherent to human tissue, has anticoagulant effect, and has little reactivity to human tissue. Especially suitable for medical materials.
