The hardness of injection-molded silicone
The hardness of injection molding silicone is a parameter that can be adjusted according to specific needs, and its hardness range is relatively wide. Generally speaking, the hardness standard of injection molding silicone is usually expressed in Shore Hardness, and the common hardness range is between Shore A 0 and A70, but some special applications may use higher or lower hardness.
Specifically, the choice of hardness of injection molding silicone depends on its application and required performance. For example, in situations where higher flexibility and elasticity are required, injection molding silicone with lower hardness may be selected; while in situations where higher hardness and wear resistance are required, injection molding silicone with higher hardness may be selected.
In addition, the hardness of injection molding silicone is also affected by factors such as its formula, production process and curing conditions. Different formulas and production processes can produce injection molding silicone with different hardness, and curing conditions (such as temperature, time, etc.) will also have a certain impact on the hardness of silicone.
It should be noted that the hardness of injection molding silicone is not the higher the better or the lower the better, but needs to be selected according to specific needs. Too high a hardness may cause the product to be too brittle and easy to break; too low a hardness may affect the shape stability and performance of the product.
