dy-made products for Soft-hardness comparison directly and then choose one of them . In nowadays the custom silicone bracelets is orubber band bracelet makerne of them. So how to choose the hardness for custom silicone bracelets . The choice of softness and hardness of silica gel will have different effects on the properties of different products . At present, the hardness of commonly used silica gel hand rings is between 40 degrees and 60 degrees and material with different hardness has certain difference . For example , the tensile rate of 40 degree materials will reach about 150% , and the tensile rate 60 degree materials can only reach about 80% .
