Siloxanes are a class of chemical compounds composed of alternating silicon and oxygen atoms, with various organic functional groups attached to the silicon atoms. They have a wide range of applications in industries such as personal care, electronics, and construction due to their unique properties such as thermal stability, water repellency, and electrical insulation. Siloxanes can be further classified based on the length and branching of their silicon-oxygen backbones, as well as the type and number of organic groups attached.
