Performance Introduction:

1. Physical and Mechanical Properties. At room temperature, the physical and mechanical properties of silicone rubber are inferior to those of general-purpose rubber, but at high temperatures of 150°C and low temperatures of -50°C, its physical and mechanical properties surpass those of general-purpose rubber.

2. Oil and Chemical Resistance. Ordinary silicone rubber has moderate resistance to oil and solvents.

3. Gas Permeability. At room temperature, the permeability of silicone rubber to gases such as air, nitrogen, oxygen, and carbon dioxide is 30-50 times higher than that of natural rubber. 

4. Physiological Inertness. Silicone rubber is non-toxic, odorless, and tasteless, does not adhere to human tissues, has anticoagulant properties, and causes minimal reaction in body tissues. It is particularly suitable for use as a medical material.

5. Low-Temperature Performance. The glass transition temperature of silicone rubber is generally between -70°C and -50°C, with special formulations reaching -100°C, indicating excellent low-temperature performance. This is highly significant for the aerospace and aviation industries.

6. Weather Resistance. The Si-O-Si bonds in silicone rubber are highly stable against oxygen, ozone, and ultraviolet light, providing excellent weather resistance without the need for any additives.

7. Electrical Properties. Silicone rubber has excellent insulation properties, with very good corona and arc resistance.

8. Temperature Range: -60°C (special down to -115°C) to 204°C (special up to 260°C)
