The luminous powder first absorbs a vrubber keyringariety of light and heat, converted into light energy storage, and then automatically luminescence in the dark, by absorbing all kinds of visible light to realize luminescence. The product does not contain radioactive elements, and can be used indefinitely, especially for short wave visible light, sunlight and ultraviolet light (UV light) under 450 nanometers. Accept the ability. Here is the properties of the luminous powder. 1st short excitation time, long duration of luminous and afterglow, high brightness. 2ndvery stable physical and chemical properties, strong environmental adaptability, ordinary service life. 3rd safe and reliable, energy saving, green environmental protection.4th The particles are small, and the fineness and granularity are evenly distributed. custom-silver-braceletsnike-rubber-bracelets elet is a real green jewelry with wear-resistant , high temperature resistance, no deformation and no side effects on body.
