Polymethylsiloxane liquid
Polymethylsiloxane liquids are widely used in industry and cosmetology due to their resistance to temperature fluctuations, excellent insulating properties and biocompatibility, which allows them to be used in lubricants, electrical insulating coatings and care products.
Chemical structure and synthesis
The main structural element is a repeating block:
[Si(CH3)2O]n
They are obtained by hydrolysis and polycondensation of monadimethyl chlorosilane, which ensures the formation of a stable silicone network.
Physico-chemical properties
They have low viscosity, high temperature resistance, chemical inertia and excellent electrical insulation. The liquid has a low tendency to form films and resists aggressive media well.
Application
They are used as lubricants, thermal and electrical insulating agents, as well as in cosmetic and medical products to create barrier and caring layers.
Conclusion
Polymethylsiloxane liquids are valuable due to their unique physico-chemical properties, which makes them versatile components in industry, electronics and cosmetology.
