ical 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 wristband is named Polysiloxanes di-Me Me vinyl vinyl group-terminated chemically. We add curing agent topvc keychain 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. Color masterbatch is the functional material for colors of the wristband. Pigment, carrier, additive is component of color masterbatch. We add it at the same time with curing agent to silicone plastic. Color masterbatch makes pigment has better dispersion in the product, keep chemical stability and stability of color. If the logo is colored, the silicone printing ink will be used. Silicone printing ink is suitable for silicone plastic product, the logo will be durable with the ink. What contains in the ink ? They are silicon dioxide, pigment, silicone oil and solvent. When the ink is dried, some of the component will evaporates. order-wristbands-onlinewaterproof-wristbands-for-events terial penetrating moral education, but also an equipment for organizing teaching .
