The choice of softness and hardness of silica gel will have different effects on the properties of different products .

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 . Size 160mm or 150mm is for youathletic silicone wristbandsnger baby.
