First, wear resistance Wear resistance is formed after the production of athletic silicone products. The surface of silicone products can resist loss. Good athletic silicone products generally have little surface friction because of external factors, do not affect the appearance of performance, text, color. However, the surface characters of inferior quality silicone products are easy to fall off. Second. Tear strength and tensile strength Athletic silicone products with high tear strength have outstanding anti destructive ability,Long life,not easily affected by external environment. Poor tearing strength of silicone products is generally manifested in the tearing process prone to cracks, thus rapidly expanding the cracking and causing damage. Third, hardness and tensile stress An important indicator of the rigidity (stiffness) of the rubber material. Hardness and elongation stress are the forces needed to produce certain deformation of silicone products.So when buying silicone products, the most important thing is to look at the wear resistance, elasticity and tear strength first. If it meets the requirements, it is a good quality silicone product. If it is not satisfied, give up, so as not to cause financial loss. Fourth. Elasticity Athletic silicone products have good elasticity because high elasticity mainly comes from the movement of molecular segments of silicone.So when buying silicone products, look at the elasticity of silicone products to judge the quality. Fifth. Fatigue resistance When the silicone product is subjected to alternating stress (or strain), the change in the structure and properties of the material is printed wristbandscalled fatigue. The fatigue damage is caused by fatigue failure as the fatigue process proceeds. camo-silicone-wristbands24-hour-silicone-wristbands Friendship is a kind of emotion from two-way relationship, that is, the emotions condensed by both sides must be maintained together.
