Precipitated silica, a form of synthetic amorphous silicon dioxide, is derived from quartz sand, a crystalline form of silicon dioxide. The physical properties of precipitated silica can be manipulated during the manufacturing process to deliver products with a wide range of performance-enhancing features engineered for many different end-use applications.
In the silicone rubber industry, Precipitated Silica not only has better tensile strength and wear resistance, but also has good transparency, no whitening and no deformation when stretched.
Arosil 185 rubber grade precipitated silica is an ultrafine nano fine chemical product, which can be divided into hydrophilic type and hydrophobic type according to the surface treatment. The appearance is a white powder.
