kind has different component. Let me show you the details. It do not contain latex. So it is good for people who has allergy to rubber. Silicone plastic is the main component. There are many kinds of silicone plastic for different fields of industrial product. Silica gel contains organic silica gel and inorganic silica gel. Silicone plastic is one of organic silica gel. Temperature resistance, Weatherability, Electrical insulation performance, Physiological inertia, Low surface tension and low surface energy are the outstanding characteristics of organic silica gel. The one we use to make wcustom keychainsristband is named Polysiloxanes di-Me Me vinyl vinyl group-terminated chemically. We add curing agent to the soft original silicone plastic and mix them evenly, then put it to molding machine with high temperature of about 200℃, a few seconds later the silicone plastic gets solidified. Here comes the silicone wristband with custom logo by mould. Characteristic of the silicone plastic stay same on the process. All of our products are made from 100% high quality silicone plastic, eco-friendly, comfortable to wear and durable. an. The glow will fade gradually in about 3h depending on how much light it absorbs. It is the best one for night event. Such music show, night walk and so on. The logo can be same as regular debossed, embossed or printed on the glowing wristbands. After exposure to natural light, fluorescent light, and ultraviolet light, the phosphor can store the light energy, stop the light and release it slowly in the way of fluorescence, so the light can still be seen at night or in the dark, lasting for hours to more than ten hours. The luminescent powder can be automatically lit in the dark. The main component is rare earth, which belongs to inorganic materials. The luminous powder first absorbs a variety 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. id-wristbands-for-eventsentry-wristbands-for-events kle, compacted neutron stars that intermittently emit radio waves that last only two milliseconds, and black crevices that last three hours. This is a process ofcustom keychains change, so we can express it by the mutil color silk print method. We can print the starburst on the surface of bracelet with the silicone based ink. We make a unique printed mold for one design. The lines of the logo is printable clearly with the smallest 0.1mm width. This kind of silicone bracelet is especially suitable for personalizing complex logo. And it touches smooth the printed bracelet style. Also there is an option to make the wrapper with starburst also. Order less than 100pcs, get 50pcs free and 5pcs keychains free. Order 100pcs or more, get 100pcs free and 10pcs keychains free.
