Polydimethylsiloxane PDMS Depending on the structure, there is PDMS; solid (three-dimensional-lattice), gummy, viscous, liquid (linear) The most common silicon is polydimethylsiloxane or dimethicones are water-repellent additives with low surface tension. Structurally, they are characterized as polymers whose basic chemical structure consists of a succession of silicon and oxygen atoms. The bond between silicon and oxygen is very strong, but very flexible; This is the reason why silicones can withstand high temperatures without decomposing, and have a very low glass transition Tg. | ||
