PG1190 – PEG POSS is a hybrid molecule with an inorganic silsesquioxane at the core and organic polyethylene glycol groups attached at the corners of the cage. This rigid core acts like molecular ball bearings and provides high film strength to reduce friction and wear. PG1190 is very stable even at high loadings and temperatures. It is also useful in lithium batteries, biomaterials, cosmetics and dispersion of oxide and carbon particles.
