In silicone raw materials, the higher the transparency, the better the quality. Therefore, many customers need to use highly transparent silicone, especially in industries such as medical devices, baby and child products, and silicone hoses.

High transparent silica gel mainly consists of precipitation method high transparent silica gel and gas phase method high transparent silica gel. Precipitation method high transparent silica gel is produced by using high mesh number precipitation method white carbon black, which is mixed and produced at high temperature in a kneading machine. After a period of vacuum treatment, we can produce precipitation method high transparent silica gel; The gas-phase method for producing highly transparent silica gel is produced using gas-phase white carbon black. Compared to precipitated white carbon black, gas-phase white carbon black has a higher mesh size and finer particles, resulting in a higher transparency of the produced silica gel raw material. The gas-phase method can even achieve a fully transparent state, so many high standard and high demand products will require the use of gas-phase silica gel.

However, although there is not much difference in appearance between ordinary high transparent silicone and gas-phase silicone, we found that stretching ordinary high transparent silicone will cause whitening, while stretching gas-phase silicone will not cause whitening. According to the current market situation, the price difference between ordinary high transparent silicone and gas-phase silicone is around yuan per kilogram. Therefore, when choosing silicone raw materials, we must consider our own production costs and choose the appropriate silicone raw materials.
