The non-toxic and environmentally friendly nature of liquid silicone products is closely related to their unique production process and raw material characteristics.
In the production process, liquid silicone products first undergo shear treatment of raw materials, followed by molding operations in a high-temperature environment of over 200 degrees Celsius. During the molding and vulcanization stage, the main substance added is the vulcanizing agent. The principle of vulcanization and molding is that the elemental sulfur and sulfur compounds in the vulcanizing agent, during the cycle of heating, pressurizing, and cooling, are separated under high pressure in a high-temperature environment. After a long period of action and fixation, the silicone products finally achieve the curing effect. The vulcanizing elements used here mainly include quinone compounds, resins, metal oxides, and amine compounds. After a series of treatments, these materials will not have any negative impacts on the environment and safety.
In terms of raw material composition, among the raw materials of all curable silicone products, white carbon black accounts for a relatively large proportion. The main components of liquid silicone raw materials are white carbon black and silicone resin, with white carbon black being in the majority. Silicon dioxide is the main body of solid silicone products. It is colorless and odorless and does not react with any substances except hydrofluoric acid and hot concentrated phosphoric acid compounds. Silicone resin belongs to thermosetting polysiloxane polymers and has good chemical properties, electrical insulation, excellent high and low temperature resistance, waterproof effects, etc. Its applications are widespread not only in the silicone field but also in multiple other fields.
In short, the main factors contributing to the non-toxic and environmentally friendly nature of liquid silicone products are that during the blending process of raw materials, the selected materials can not only ensure normal curing and molding but also do not conflict with other substances. The basis for their harmlessness is the characteristic of the raw materials not conflicting with other substances, which makes liquid silicone products a safe and environmentally friendly high-quality material.
