CR O-Rings are seals made from Chloroprene Rubber, also known as Neoprene. Chloroprene rubber is a synthetic rubber made by polymerizing chloroprene monomers. It has good weather, oil, chemical and mechanical resistance and is therefore widely used in a variety of industrial applications. Here are some details of CR O-Ring:

What is the CR O-rings Material Properties ?

• Weathering resistance: Neoprene has good weathering and UV resistance and is resistant to the effects of climate change and ozone.
• Oil Resistance: Neoprene has excellent resistance to petroleum-based oils, lubricants and fuel oils, making it ideal for oil-resistant seals.
• Chemical resistance: Neoprene is resistant to a wide range of chemicals, including water, dilute acids, dilute alkalis and certain organic solvents.
• Temperature resistance: Chloroprene rubber’s temperature range is generally between -30°C and +120°C, with some specially formulated neoprene rubber able to withstand higher temperatures.
• Mechanical properties: neoprene rubber has good elasticity and resistance to permanent deformation in compression, abrasion resistance and tear resistance is also good.
• Flame retardancy: Neoprene has some flame retardant properties, making it suitable for use in applications requiring fire protection.

Which is the CR O-rings Application Areas ?

CR O-rings are widely used in the automotive industry, construction, chemical, oil and gas, electrical and electronic, sports equipment and other industries for sealing oil pipes, hydraulic systems, water pipes, chemical transportation pipes and so on.

How is the CR O-rings Manufacturing Process ?

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

What Specifications and Standards does CR O-rings follow ?

CR 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: Neoprene materials should be stored in a dry, cool, well-ventilated place, away from direct sunlight and high temperatures.
• Use environment: Although neoprene rubber is resistant to oil and chemicals, it may be affected in certain polar solvents and strong oxidizing agent environments.
• Installation requirements: CR O-rings should be installed without scratching or twisting to ensure sealing effectiveness.
• The selection and use of CR O-rings need to be determined according to the specific application environment and requirements to ensure the best sealing effect and service life.
