Some customer are holding ready-made products for Soft-hardness comparison directly and then choose one of them . In nowadays the custom silicone bracelets is one 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 rubber band braceletsmaterials will reach about 150% , and the tensile rate 60 degree materials can only reach about 80% . So in order to confirm the functionality of products , we have to test them . It is more difficult to produce high hardness silica gel hand rings . For the manufacturers of silica gel hand rings , the higher the hardness , the higher the defective rate of the products and the pulling force of the products will also be affected and will cause fracture phenomenon at any time . Therefore , we suggest that the hardness of the silica gel hand rings should not be too high .
