Product Description
Precipitated silica, alternatively referred to as hydrated silica or white carbon black, holds significance as an inorganic chemical product. Silicon dioxide (SiO2) constitutes its primary component, with a certain quantity of bound water usually present, and it can be denoted as SiO2·nH2O. It presents itself in the form of a white amorphous powder. It is non - toxic, odorless, and insoluble in water as well as the majority of organic solvents.

Application
Fumed silica functions as an extremely potent reinforcing agent and has the capacity to remarkably enhance the physical and mechanical attributes of rubber. Once it interacts with the rubber's molecular chains, physical or chemical cross - linking sites are produced. These cross - linking sites play a crucial role in effectively augmenting the rubber's tensile strength, tear resistance, and abrasion resistance.
In the domain of tire production, the incorporation of fumed silica into rubber gives rise to tires that possess enhanced puncture - resistance and anti - wear characteristics. This ultimately leads to an extension of the tires' service life and an elevation in their safety standards.
Fumed silica, when introduced into plastics, can effectively improve the strength, hardness, and toughness of these substances. For example, in the case of engineering plastics such as polyamide (PA) and polycarbonate (PC), after the addition of fumed silica, the tensile strength and flexural modulus of these plastics increase significantly. This enhancement enables the plastics to withstand much larger external forces, maintaining their integrity without deforming or getting damaged, even when subjected to substantial stress.
