This product is for its unique properties, can be used to adjust the crystallinity, degree and apparent density of polyolefin products; it can be used alone or paired with other electronics to accommodate the production of different polypropylene; the performance and efficiency of the catalyst when used with a variety of catalysts.

Tetraethyl orthosilicate (TEOS) is a colorless, transparent liquid with the chemical formula Si(OEt)4. It is an organosilicon compound that is commonly used as a precursor to silicon dioxide in various industrial applications.

TEOS is a silicate ester that undergoes hydrolysis and condensation reactions in the presence of water, leading to the formation of silica nanoparticles. This process is known as the sol-gel process and can be used to produce thin films, coatings, and other materials.

TEOS is particularly useful in the microelectronics industry, where it is used as a source of silicon dioxide for chemical vapor deposition (CVD) processes. These processes are used to deposit thin films of silicon dioxide on the surface of microchips and other electronic components.

In addition, TEOS has also been used in nanotechnology research for the synthesis of silica nanoparticles and other nanostructured materials. It is considered to be a relatively safe chemical but should still be handled with care as it may cause skin and eye irritation upon contact.
