Advantages of Hose SBR Rubber Seal Ring
- Good elasticity: SBR rubber has excellent flexibility, which allows it to maintain a tight seal even under changing pressure conditions. This elasticity helps absorb shock and vibration, making it suitable for dynamic applications.
- Temperature resistance: SBR rubber can operate effectively in a temperature range of approximately -20°C to +70°C. This range allows it to be used in many outdoor and industrial applications without quickly degrading.
- Cost-effectiveness: SBR is relatively inexpensive to produce and purchase compared to other rubber materials, making it a cost-effective choice for sealing solutions in various industries.
- Easy to manufacture: SBR can be easily molded and shaped into different shapes, which helps in making customized seals that meet specific requirements.
- Versatility: Due to the adaptability of SBR rubber seals, they can be widely used in automobiles, industrial machinery, household items, etc.
Why SBR as Hose SBR Rubber Seal Ring?
(1) The rubber material is not easy to scorch and over-sulfur and the vulcanization flatness is good.
(2) Wear resistance, heat resistance, oil resistance, and aging resistance are better than natural rubber. High-temperature wear resistance.
(3) The molecular weight is no longer reduced after the processing to a certain extent, so it is not easy to refine, and the plasticization is uniform.
(4) High filling can be achieved by increasing molecular weight.
(5) It is easy to use with other unsaturated general rubber, especially natural rubber, and butadiene rubber, and the shortcomings of styrene butadiene rubber can be overcome by formula adjustment.
