Yellowing of silicone products: The most common silicone case is the silicone mobile phone case. The yellowing phenomenon is the essence of ordinary silicone products. Generally, the product will turn yellow after being used for too long after environmental changes, but anti-yellowing is added from it. The agent can achieve the phenomenon of non-yellowing, or the use of food-grade silica gel raw materials and fumed silica raw materials, high-transparency, high-strength, and high-quality silica gel materials will not turn yellow. If the product you buy is ordinary silicone and no anti-yellowing agent is added, it will cause the product to turn yellow. Therefore, when purchasing silicone sleeves, don’t be greedy for cheapness. The price of the product depends on the quality of the product.
In addition, it may also be the production process. If the temperature of the production mold is too high or the vulcanization process takes a long time during molding, it may also cause the color of the silicone product to turn yellow, which requires us to strictly control the production results. If the temperature of the mold and the curing time of the product are not well controlled, many situations will occur.
Although there are many reasons for the yellowing of silicone products, the way we can avoid them is that we must choose excellent manufacturers for custom silicone products, and will not use inferior raw materials and mature production processes. It will not cause low quality of the final product.
The silicone raw materials used by our Weishun Silicone Products Technology Co., Ltd. are all high-quality food-grade silicone, which has passed the FDA and LFGB testing. At the same time, we have more than 15 years of production experience and are very familiar with the characteristics and shortcomings of silicone products. We will recommend suitable processes to customers according to product uses and characteristics, in order to make the most suitable products.
