Silicone rubber products are widely used for its excellent properties like high temperature resistance, electrical insulation and external flexibility, among which, the most obvious feature lies in its odorlessness. However, in recent years some silicone rubber products have been found to have odors. What causes the odor of these products?
The main cause of the odor is bacteria generated from raw materials and never property purified. For example, styrene, a major component of silicone rubber, can easily generate bacteria when exposed to air or moisture-containing environment during storage and transportation. In addition, additives used in silicone rubber, such as stabilizers, softeners, accelerators and fillers, may also act as a source of odor if the amount or quality is not well controlled.
Finally, improper production processes can also cause the silicone rubber to emit odors. Thus, it is necessary to maintain good hygiene during the production process, optimize the production process, and use high-quality raw materials to avoid the odor of silicone rubber products.
