In silicone raw materials, the higher the transparency, the better the quality. Therefore, many customers need to use high transparent silica gel, especially in medical devices, baby and child products, silicone tubes and other industries.

The highly transparent silica gel mainly consists of the highly transparent silica gel produced by precipitation method and the highly transparent silica gel produced by gas phase method. Precipitation method high transparent silica gel is produced by high mesh precipitation method white carbon black. It is produced by mixing at high temperature in the kneader. After a period of vacuum treatment, we can produce precipitation method high transparent silica gel; The gas phase silica gel with high transparency is produced by using vapor phase white carbon black. Compared with the precipitated silica, the vapor phase white carbon black has a higher mesh number and finer particles, so the transparency of the silica gel raw materials produced is higher. The gas phase silica gel can even be fully transparent. Therefore, many products with high standards and requirements will need to use the gas phase silica gel.

However, although there is little difference in appearance between ordinary high transparent silica gel and gas phase silica gel, we can draw ordinary high transparent silica gel and it will turn white, while gas phase silica gel will not turn white. According to the current market situation, the price difference between ordinary high transparent silica gel and gas-phase silica gel is about RMB/kg. Therefore, when selecting silica gel raw materials, we must consider our own production costs to select appropriate silica gel raw materials.
