In the industrial field, O-ring as a basic sealing element, its importance is self-evident. Liquid silicone (LSR) O-rings are becoming the preferred sealing material for an increasing number of industries due to their superior physical and chemical properties.
What is a liquid silicone O-ring?
Liquid silicone O-ring is a kind of high precision seal made of liquid silicone rubber (LSR). LSR is a two-component silicone rubber cured by catalytic addition of platinum
. This material cures to form a solid material that is soft, elastic and resistant to chemical corrosion, making it ideal for use as a seal.
The characteristics of liquid silicone O-rings
Liquid silicone O-rings have the following notable characteristics:
- Wide temperature range: can be used at -60 ° C to 225 ° C for a long time, suitable for extreme temperature environment
- Biocompatibility: suitable for contact with food and drugs, often used in medical equipment and food industry equipment
- Electrical insulation: has excellent electrical insulation properties, suitable for electronic and electrical equipment
- Chemical resistance: No reaction to most chemicals, including water, acids and bases
Application field
Liquid silicone O-rings are widely used in many industries due to their unique properties:
- Medical industry: Used for medical devices and equipment, such as syringes, medical pipelines, etc
- Food and beverage: For food processing equipment that requires sealing, such as beverage dispensers and packaging machinery
- Automotive industry: cooling systems, fuel systems and transmission systems for automobiles
- Electronics industry: Used for sealing of electronic equipment to protect the circuit from moisture and dust erosion
Market prospect
With the advancement of technology and the growth of market demand, the market for liquid silicone o-rings is expected to continue its growth momentum in the next few years
Especially in the medical and food processing industries, there is a rising demand for high-performance sealing materials.
Conclusion
