SBR O-rings are seals made of Styrene-Butadiene Rubber (SBR). Styrene-Butadiene Rubber (SBR) is a synthetic rubber made from the copolymerization of styrene and butadiene, and it is one of the most widely produced synthetic rubbers in the world.SBR rubber has good abrasion resistance, aging resistance, and mechanical properties, and is widely used in a variety of industrial applications. Here are some details of SBR O-Ring:

Waht is the SBR O-rings Material Properties ?

• Abrasion resistance: SBR rubber has good abrasion resistance and is suitable for use in applications where abrasion resistance is required.
• Aging resistance: SBR rubber has a certain degree of aging resistance, able to resist the effects of ultraviolet rays and ozone.
• Temperature resistance:SBR rubber’s temperature resistance generally ranges from -40°C to +100° Certain specially formulated SBR rubber can withstand higher temperatures.
• Chemical resistance: SBR rubber has a certain degree of resistance to water, dilute acid, dilute alkali and certain non-polar solvents, but the resistance to oil and certain polar solvents is poor.
• Mechanical properties:SBR rubber has good elasticity and resistance to compression permanent deformation, but its oil resistance and tear resistance are not as good as some other rubber materials.

Which are the SBR O-rings Application Areas ?

SBR O-rings are widely used in automotive tires, conveyor belts, rubber flooring, shoe materials, seals, gaskets, hoses and other fields. In sealing applications, SBR O-Rings are commonly used in general industrial equipment, agricultural machinery, construction machinery, etc. for sealing water, air and some non-polar liquids.

How does the SBR O-rings Manufacturing Process ?

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

What is the SBR O-rings Specifications and Standards ?

SBR 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: SBR rubber material should be stored in a dry, cool and well-ventilated place, avoiding direct sunlight and high temperature.
• Use environment: Although SBR rubber has good abrasion and aging resistance, it may be affected in oil and some polar solvent environments.
• Installation requirements: avoid scratching or twisting when installing SBR O-rings to ensure the sealing effect.The selection and use of SBR O-rings need to be determined according to the specific application environment and requirements to ensure the best sealing effect and service life.
