Today, we will briefly introduce several common silicone oils in silicone industry, their performance characteristics and application range. Let's look at the difference between hydroxyl silicone oil, hydrogen containing silicone oil and methyl silicone oils.

1. Hydroxy silicone oil

Hydroxy silicone oil is a colorless transparent liquid with excellent electrical insulation and high and low temperature resistance, high flash point and low freezing point. It can be used for a long time under the condition of -50°C to +250°C, with small viscosity temperature coefficient, high compression ratio, low surface tension, good moisture resistance, chemical inertia and physiological inertia.

Usage: mixed with crosslinking agent and catalyst, it can be solidified at room temperature. It is the main component of leather smoothing agent. It can also be used as leather brightener and release agent.

2. Hydrogen containing silicone oil

Usage: under the action of metal catalyst, it can be crosslinked at appropriate temperature to form waterproof film on the surface of various substrates. It is widely used as waterproof agent, anti adhesion agent or corrosion inhibitor for fabrics, fire extinguishing agents (dry powder), paper, metal, leather, wood, glass, cement, ceramics, marble, etc.

3. Methyl silicone oil

Methyl silicone oils are colorless, tasteless and non-volatile. It is insoluble in water, methanol and glycol, and is miscible with benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride or kerosene. It has low vapor pressure, high flash point and ignition point. Methyl silicone oil has excellent heat resistance, electrical insulation, weather resistance, hydrophobicity, physiological inertia and small surface tension. It also has low viscosity temperature coefficient and high compression resistance.

Usage: methyl silicone oil is widely used in electronic and electrical appliances, building materials, motor manufacturing, transportation, petrochemical, textile, printing and dyeing, thread making, various polyester, polyester cotton and polyester man-made cotton fabrics, as well as medicine and health, aviation research and military technology.
