piidiöljyihin

Piidiidiöljyihin, known in English as silicone oils or polydimethylsiloxanes (PDMS), are synthetic polymers composed of silicon and oxygen atoms, with organic side chains. They are a versatile class of compounds characterized by their unique properties, including thermal stability, water repellency, low surface tension, and excellent dielectric properties. These characteristics make them suitable for a wide range of industrial and commercial applications.

The general chemical structure of silicone oils involves a repeating silicon-oxygen backbone. The specific properties of a silicone oil can be modified by varying the length of the polymer chains and the type of organic groups attached to the silicon atoms. For instance, longer chains generally lead to higher viscosity.

Applications for silicone oils are diverse. They are commonly used as lubricants, hydraulic fluids, and heat transfer fluids due to their stability over a wide temperature range and resistance to oxidation. In the cosmetic and personal care industry, they are employed as emollients, conditioners, and protective agents in products like lotions, shampoos, and makeup. Their water-repellent nature also makes them useful in waterproofing treatments for textiles and construction materials. Furthermore, their electrical insulating properties find use in electronic components and transformers. Silicone oils are also utilized as antifoaming agents in various industrial processes and in food production.
