Ethyl silicate Crosile Si40 is a concentrated form for obtaining usable silica. It is a partially hydrolyzed mixture of monomers, dimers, trimers, higher polymers and cyclic polysilicates.
Tetraethyl orthosilicate, also known as tetraethoxysilane (TEOS), is an organic compound denoted by the formula Si(OC2H5)4. This colorless liquid undergoes degradation when exposed to water. TEOS serves as the ethyl ester of orthosilicic acid, Si(OH)4, and is widely recognized as the predominant silicon alkoxide.
Ethyl Silicate-28 is a monomeric ethyl silicate, also known as tetraethyl orthosilicate (TEOS). After hydrolysis, it yields 28 wt.% silica, hence the name Ethyl Silicate-28. It has the following chemical formula.
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.
