Excavator Hydraulic Seal BRT2 Back-Up Ring
The back-up ring is used to increase the service life of the seal. For the selection of the retaining ring material, it is required to have the characteristics of being easy to compress and deform when pressurized and difficult to be extruded. In addition, during compression deformation, it moves due to contact with the opposed sliding surface, so wear resistance and low friction characteristics are also important

PU Material Performance Characteristics:
(1) Specific gravity: lighter.
(2) Mechanical properties: good impact resistance, but high water absorption.
(3) Wear resistance: self-lubriC-A-Ting, low abrasion, mostly used in the manufacture of shaft sleeves, gears, scroll bars and other products.
(4) Electrical performance: Due to the influence of moisture and crystallinity, it can only be used for components with comprehensive performance in electronic and electrical.
(5) Flammability: self-extinguishing.
(6) Chemical resistance: In addition to strong acids, strong alkalis, zinc chloride and other chemicals, it is resistant to various chemicals.
(7) Heat resistance: high heat resistance, for example, the softening point of PA66 is 260°C, PA6 is 224°C, and PAl2 is 117°C.
(8) Breathability; low permeability for O and CO, suitable for food packaging film. Due to its high air permeability, it can also be solved by a multilayer composite process with aluminum foil.
(9) After the glass fiber is reinforced, the water absorption and dimensional stability can be greatly improved.
PA Performance Characteristics:
1. High strength: working pressure 0.6~4 OMpa;
2. Maximum working pressure is much higher than existing plastic pipes;
3. Lightweight: the weight is only 1/7 of the steel pipe, and the weight in the water is only 1/48 of the steel pipe;.
4. Wear resistance: under the same working conditions, the wear resistance is 3~4 times that of steel;
5. Temperature resistance: working temperature is-40C~150C, not cold and brittle at low temperature;
6. Corrosion resistance: resistant to strong alkali, weak acid and most salt media;
7. Large diameter: the product diameter is 160~1000mm, the maximum diameter is larger than the existing plastic pipe diameter;
8. Low friction: Under the same working conditions, the pipeline pressure loss is only 2/3~4/5 of the steel pipe;
9. Impact resistance: impact toughness is equivalent to steel pipe;
10. Anti-aging: The service life in the field can reach more than 50 years;
11. Easy connection.
