The functions of silicone mainly include the following aspects:
High and low temperature resistance: Silicone products have excellent high and low temperature resistance. Because its main chain is a silicon-oxygen bond (Si-O), the bond energy is high, so it has high thermal stability. Silicone products are not only resistant to high temperatures, but also maintain good performance in low temperature environments, and are suitable for applications in a wide temperature range.
Electrical insulation performance: Silicone products have good electrical insulation performance. Its dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity and surface resistivity are among the best in insulating materials, and are little affected by temperature and frequency, and are suitable for the electronics and electrical industries.
Weather resistance: The main chain of silicone products is a silicon-oxygen bond, there is no double bond, it is not easily decomposed by ultraviolet light and ozone, and has excellent weather resistance. Its service life in natural environment can reach decades.
Low surface tension and low surface energy: The main chain of silicone is flexible, the intermolecular interaction force is weak, the surface tension is low, the surface energy is small, and the film-forming ability is strong. This property makes silicone excellent in hydrophobicity and defoaming.
Physiological inertness: Polysiloxane compounds are one of the most inactive compounds known, resistant to biological aging, have no rejection reaction with animal bodies, and have good anticoagulant properties.
Other properties: Silicone is also flame-retardant, hydrophobic, corrosion-resistant, non-toxic and odorless, and is widely used in aviation, home furnishings, clothing, textiles, medical devices, home appliances, cosmetics and personal care products.
