stomer are holding ready-made products for Soft-hardness comparison directly and then choose one of them . In nowadays the custom silicone bracelets is one of them. So how to choose the hardness for custom silicone bracelets . The choice of softness and hardness of silica gel will have different effects on the properties of different products . At present, the hardness of commonly used silica gel hand rings is between 40 degrees and 60 degrees and material with different hardness has certain difference . For example , the tensile rate of 40 degree materials will reach about 150% , and the tensile rate 60 degree materials can only reach about 80% . So in order to confirm the functionality of products , we have to test them . It is more difficult to produce high hardness silica gel hand rings . For the manufacturers of silica gel hand rings , the higher the hardness , the higher the defective rate of the products and the pulling force of the products will also be affected and will cause fracture phenomenon at any time . Therefore , we suggest that the hardness of the silica gel hand rings should not be too high . their own advantages . We are alsosilicone wristbands bulk engaged in the production of personalized rubber bracelets ,we have more experience in the production of cool silicone wristbands . As a rubber band bracelets maker ,we also have our own advantages . 1.We will use the pure silica gel to produce the personalized rubber bracelets .The advantage of high quality silicone wrist band is environmental friendly and Non-toxic side effects .It does not harm the human body and it"s not easy to break . 2.The edge of our personalized rubber bracelets is smooth .When the silicone bracelet was produced out ,we need to trim the edge of the wristband .We used to trim the edge of bracelets with scissors ,but now ,we will use the professional machine to trim the edge of the personalized rubber bracelets that the edge of our cool silicone wristbands is smooth . 3.Our personalized rubber bracelets are very clean .When the production of silicone wrist band is completed ,we will clean the wristband ,because the silicone wristband will get dirty during production . 4.Our transportation is very fast .When we finish the silicone wristband ,we will choose the most suitable express company to ship the wristbands out .The express companies that cooperate with us are FEDEX ,UPS and so on . wristbands-with-a-messagecustom-silicone-bracelets s not been mixed with various additives. Silicone plastic is the main component of our wristband. There are many kinds of silicone plastic for different fields of industrial product. Silica gel contains organic silica gel silicone wristbands bulkand 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 wristband 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. Due to the feature of silicone plastic, we can make the wristband in all shapes, all sizes and all colors. So we are able to creat all kind of custom wristband. Welcome to place an order soon.
