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 materials 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 . the silicone. The silicone has the open vesicular strucblack wristbandsture , large specific surface. So it can absorb many substances as a good desiccant, adsorbent and catalyst carrier. Adsorption of the silicone is mainly the physical one that can be regenerated and good for repeated use. Let the silica gel soak in the cobalt dichloride solution then get it dried and activated , will become the allochroic silica gel. It will transfer from blue to red color when absorb water. Changes in color shows the degree of water absorption and whether need the regeneration treatment.
