Yellow silicone ring, in simple terms, the silicone ring made of yellow color. The color of the silica gel circle, can make any color, transparent, red, green, blue, black, white, translucent, and so on, products include silicone o-rings, silica gel, silica gel ring U, silica gel, silica gel Y type V circle, silicone rectangular circle, etc. The silicone ring is a ring!Silica gel is a kind of rubber material, wide because of its special properties of heat resistance, excellent chemical resistance, together with the fluorine rubber was thus became a special rubber.Silicone is widely used in making all kinds of seals, including silicone RING, silicone O - RING, silicone sets, etc.
Silicone ring has excellent heat resistance, low temperature flexibility and special excellent oxidation and ozone resistance, high permeability and selectivity of gas through.Good electrical insulating properties (volume resistance is greater than 10 cm, breakdown voltage in more than 30 kv/mm), corona resistance and arc resistance.But add a conductive carbon black, nickel powder, aluminum powder, silver powder, and can get the appropriate electrical conductivity (volume resistance to 5-0.02 euro. Cm).The surface of the silica gel circle can lower, with moisture absorption and isolation effect.Water resistance, but poor resistance to water vapor, the pressure more than 50 psi is not recommended.Compatible with most of the oil, chemicals and solvents.General silicone rubber acid-proof alkaline, polar solvent resistance, resistance to hydrogen alkanes and aromatic oils.Not recommended for most concentrated solvent, oil, concentrated acid and diluted caustic soda solution.Special silicone rubber has radiation resistant, flame resistant, oil resistant performance.Its low tensile strength, abrasion resistance is weak, is generally not used for dynamic seal.
The silicone ring is based on the silicon from quartz, and adhered to by the silicon atoms such as methyl, vinyl side chain to form a saturated nonpolar rubber.The different side chains can lead to silicone rubber with different properties.Methyl vinyl silicone rubber (VMQ) is a kind of silicone rubber material application.
