1. Exceptionally Wide Temperature Range
Advantage Description: This is silicone's most prominent advantage. Standard silicone maintains elasticity over -60°C to +200°C for extended periods, while specialty silicones (e.g., phenyl silicone) withstand temperatures as low as -100°C and as high as +300°C (short-term).
Practical Significance: Suitable for high-temperature environments like baking ovens, heating equipment, and automotive engine compartments, as well as low-temperature applications such as refrigeration systems and aerospace, without significant performance degradation.
2. Superior Weather Resistance and Aging Resistance
Advantage Description: Silicone's backbone consists of Si-O bonds, whose bond energy far exceeds that of C-C bonds. This provides exceptional resistance to environmental factors like UV radiation, ozone, sunlight, rain, and snow. Unlike most rubbers, it does not crack, harden, or chalk when used outdoors long-term.
Practical Significance: An ideal material for outdoor sealing applications (e.g., building curtain wall gaskets, automotive sunroof seals) with exceptionally long service life.
3. Outstanding Chemical and Physiological Inertness
Advantage Description: Silicone exhibits stable chemical properties, demonstrating good resistance to most chemicals and solvents except strong acids and alkalis. It is non-toxic, odorless, non-corrosive, and possesses excellent biocompatibility.
Practical Significance:
Food Grade: Certified by FDA, LFGB, etc., widely used for sealing in kitchen appliances, baby products, and food processing equipment.
Medical Grade: Certified by USP Class VI, etc., suitable for medical devices, pharmaceutical equipment, and implantable devices, ensuring safety and harmlessness to the human body.
4. Excellent Electrical Insulation Properties
Advantages: Silicone rubber is an outstanding insulating material. Its electrical properties remain stable across a wide range of temperatures and frequencies, maintaining reliable insulation even in high-humidity environments.
Practical Applications: Widely used for wire and cable insulation, sealing high-voltage electrical connectors, and encapsulating electronic components for protection.
