Black Good Water Resistance Duro 80 SBR Seal Styrene Butadiene Rubber Oring
SBR material
| Material | SBR(Styrene Butadiene Copolyme) |
| Advantage | 1.Good Water Resistance |
| 2.Good Rebound Resistance(less than 70shore) | |
| Disadvantage | Poor chemical resistance |
| Poor Tear Resistance ,Rebound Resistance | |
| Temperature | -30~100 ℃ , -40~110 ℃(special formula) |
| Application | For tire ,hose ,conveyor belt etc. |
SBR Rubber Features:
1.Main materials: Styrene-butadiene rubber (SBR), a general-purpose synthetic rubber,
produced from a copolymer of styrene and butadiene. Exceeding all other synthetic rubbers
in consumption, SBR is used in great quantities in automobile and truck tires, generally
as an abrasion-resistant replacement for natural rubber (produced from polyisoprene).
2.Available place: They are widely used in automobile, electrical appliances, building vibration
isolation and other industry. For example, air blower, water pump, instrument, measuring
of ships and so on.
3.Main performance: SBR has similar chemical and physical properties to natural rubber,
with generally better abrasion resistance,outstanding strength,good creep and stress relaxation
resistance and low cost,etc. It is not recommended to use SBR in applications that involve ozone,
strong acids, oils, greases, fats and most hydrocarbons.
1.The O-ring is an annular seal having an O-shaped cross section, the size of which is determined
by the inner diameter ID and the wire diameter CS.
2.O-ring size calculation: outer diameter = inner diameter + 2 x wire diameter (OD = ID + 2x CS).
3.The purpose of using O-ring seals is to prevent leakage and loss of liquids or gases.
4.O-rings are the most commonly used type of seal because of their simplicity, convenience, and
small installation space. As long as the groove design and material selection are correct, and the
operating conditions are within the temperature range of the rubber material, the seal can have a
long-term sealing effect in the static or dynamic seal.
