Rubber gaskets of sealing parts
Rubbe gaskets of machine sealing parts:
1. This kind of rubber gaskets are not the same with the usual ones, it is more thin than the normal rubber gaskets.
2. Round holes with different sizes on its surface, for fitable with the iron parts, for strong function.
3. We have different material to make and can make different sizes.
4. We have strict quality control system and management.
5. We have professional facility to test the rubber gaskets' feature.
The following chart is the data of testing procedure:
Test Parameter | Test Method | Specification | Test result Min Max |
Shore Hardness °Shore A | ASTM D2240 | 80 | 72 76 |
Tensile strength, in MPa, min | ASTM D412 | 10.3 | 15 18 |
Elongation, @Break % min | 150 | 325 444 | |
Compression Set, % @70°C/ 22 hours | ASTM D395 Method B | 20% | 11% 19% |
Ozone Resistance 25hrs / 50 pphm Ozone / 40°C | ASTM D1149 | No Cracks | No Cracks |
Oxygen Bomb (96 hrs. in Oxygen @ 70°C/300 psi ) | ASTM D572 |
|

1) Retention of Tensile Strength, % | 60% | 82.9% | |
2) Retention of Elongation, % | 60% | 95% |
