ne wristband. A UV silicone bracelet can transfer it’s color darker under sunshine when absorbing UV light. It transfer to purple or blue normally which indicating the strength of the UV index. Wearing it on the wrist is a good way to avoid long time staying under strong sunshine. We add UV powder which is also green as silicone in production. The UV powder is kind of photochromic material. We use it to make this change. Photoreceptor color is irradiated by ultraviolet or sunlight, absorbs ultraviolet or sunlight, and produces changes in color. When it loses ultraviolet or sunlight, it returns to the original color. Photoreceptor products, after sunlight or ultraviolet radiation, can absorb the energy of the sun or ultraviolet rays, produce changes in the molecular structure, lead to changes in the absorption wavelength, and produce color changes; when the sun or ultraviolet energy is lost, the original molecular structure is restored and the color of the cost is reduced. Application of photosensitive discoloration material: coating, suitable for various surface coating products, including PMMA spray paint, ABS spray paint, PVC spray paint. Ink, printing of various materials, including fabric, paper, synthetic film, glass, etc. Plastic products, suitable for various kinds of plastic PP, PVC, ABS, silicone rubber and other materials, such as the ejection, out of shape.       waterproof-wristbands-for-eventsevent-wristbands-walmart

icone products.So how do we judge the quality of silicone products when we buy silicone products? 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 molecucustom silicone wristbandslar 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 called fatigue. The fatigue damage is caused by fatigue failure as the fatigue process proceeds.       camo-silicone-wristbands24-hour-silicone-wristbands
