Characteristics of Silicone R

1. Exceptional Weathering and Aging Resistance:

The main chain of silicone products is -Si-O-, without double bonds, making it resistant to decomposition by UV light and ozone. Silicone exhibits superior heat stability, radiation resistance, and weather resistance, leading to a service life of several decades in natural environments.

2. Outstanding Heat Stability:

High thermal stability, with chemical bonds remaining intact and not breaking or decomposing even at high temperatures or under radiation. Silicone is capable of withstanding a broad temperature range, maintaining stability in both chemical and mechanical properties.

3. Excellent Waterproofing:

Possesses outstanding water repellency, ensuring high reliability for electrical equipment in humid conditions. Silicone rubber China, located under the engine hood in automobiles, protects electronic components from moisture and dirt.

4. Superior Adhesive Performance:

Demonstrates the ability to adhere similar or different materials upon contact.

5. UV Resistance:

Absence of double bonds makes silicone resistant to decomposition by ultraviolet light.

6. Ultra-Low Volatility:

Rapid curing into durable elastic material at high temperatures, suitable for applications sensitive to volatile siloxanes.

7. Chemical Resistance:

Capable of withstanding acids, alkalis, salts, solvents, and other chemicals.

8. Persistent Elasticity, Toughness, and Adaptability:

Good flowability and ease of operation, with resistance to internal hardening caused by sustained heating and temperature changes. Silicone material maintains prolonged elasticity and toughness, ensuring the reliability and longevity of electronic components.

9. Outstanding Electrical Insulation:

Silicone products boast excellent electrical insulation properties, ranking high in dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity, and surface resistivity among insulation materials. Their electrical performance is minimally affected by temperature and frequency, making them stable insulation materials widely used in the electronics and electrical industries.

10. High Tensile Strength:

Silicone products exhibit excellent tensile strength, and their elongation rate can be significantly altered by different processing methods and choices of curing agents. The elongation rate of silicone rubber is closely related to temperature.

11. Defoaming Performance (Low Surface Tension and Low Surface Energy):

The flexible main chain of organic silicon results in weaker intermolecular forces compared to hydrocarbons. This leads to low viscosity, low surface tension, low surface energy, and strong film-forming ability. These properties make silicone widely applicable for various purposes such as hydrophobicity, defoaming, foam stabilization, anti-adhesion, lubrication, and gloss enhancement. Silicone defoaming agents, for instance, are used in washing machines to prevent excessive foaming of detergents.
