The change of extrusion strength, low hardness products will gradually reduce the strength, high hardness will increase, and 5-10 degrees of difference will have different extrusion changes.

The change in tear resistance, the higher the hardness of the product tear resistance will be weaker, especially with right Angle products are prone to tear, the lower the hardness of the tear is better, different hardness of the tear is different.

Constant extension stress leads to deformation. Constant extension stress is an important control index of silicone rubber material, which has a certain correlation with hardness.

Wear resistance and fatigue changes, different hardness of products in wear resistance and fatigue have different effects, general silicone rubber material with the increase of crystallinity hardness, long-term running-in will affect fatigue decline wear resistance is not enough.

The difference in elasticity, elasticity is one of the important elements in silicone material, so different hardness of the material has an impact on each different application of the product, and the hardness of the difference is too large may lead to the use of the whole product, and even affect the whole each link!

Many customers fail to correctly indicate the use of hardness when purchasing silicone rubber products. There are no requirements for the hardness of materials, but the choice of the hardness of silicone rubber products is likely to affect the use effect of the whole product
