Silicone O-Ring is a type of seal made with Silicone Rubber (Silicone Rubber) material, which has excellent resistance to high and low temperatures, aging, and electrical insulation, and is therefore widely used in many industrial and consumer applications. Below are some details about Silicone O-Rings:

Waht is the Silicone O-rings Material Properties ?

• Temperature resistance: Silicone rubber is able to maintain its properties over a wide range of temperatures, typically ranging from -60°C to +200°C, with some specially formulated silicone rubber able to withstand even higher temperatures.
• Weathering resistance: Silicone rubber has good resistance to UV rays and climate change, making it suitable for outdoor use.
• Aging resistance: Silicone rubber has good aging resistance and is able to maintain its elasticity and sealing properties in long-term use.
• Electrical insulation: Silicone rubber has good electrical insulation properties, suitable for sealing electrical and electronic equipment.
• Chemical stability: Silicone rubber has good resistance to most chemicals, but poor resistance to some solvents (such as hydrocarbon solvents).
• Physiological inertness: Silicone rubber is harmless to humans and is suitable for use in the medical and food processing industries.
• Mechanical properties: Silicone rubber has good elasticity and resistance to permanent deformation in compression, but its strength and abrasion resistance are not as good as other rubber materials.

Which are the Silicone O-rings Application Areas ?

Silicone O-rings are widely used in aerospace, automotive, electronics, medical, food processing, household appliances and other industries for sealing high temperature, low temperature or need good electrical insulation properties of equipment and piping.

How does the Silicone O-rings Manufacturing Process ?

Silicone O-rings are typically manufactured through a molding or extrusion process. Molding is to put the pre-mixed silicone rubber material into the mold and form it under high temperature and high pressure; extrusion is to extrude the silicone rubber material into the shape of O-ring through the extruder, and then vulcanize it.

What are the Silicone O-rings Specifications and Standards ?

Silicone O-rings are available in a variety of sizes and hardnesses that can be customized for different applications. Common standards include ISO 3601 (international standard), AS 568 (American standard), etc.

What should we pay attention to ?

• Storage conditions: Silicone rubber materials should be stored in a dry, cool, well-ventilated place, avoiding direct sunlight and high temperatures.
• Use environment: Although silicone rubber is resistant to high temperature and aging, it may be affected in certain solvent and oil environments.
• Installation requirements: Avoid scratching or twisting when installing silicone O-rings to ensure the sealing effect. The selection and use of silicone O-rings need to be determined according to the specific application environment and requirements to ensure the best sealing effect and service life.
