Fluor-Siloxane


Fluorine-modified siloxanes become products that are very resistant to hydrocarbons, esters and oxidation. They can also be used in a wide temperature range (-60°C to 290°C). Fluorosilicones do not have methyl groups on their siloxane chains, but fluoroalkyd groups. This makes them even more temperature and oxidation resistant than all other siloxanes (PMPS). They come in the form of oils, fats and pastes. Fluore-siloxanes are used, among other things, as lubricants for extreme temperatures, defoamers, compressor and hydraulic oils.



Polymethyltrifluoropropylsilicones in particular have gained technical importance as fluorosilicone rubbers (short name MFQ or FMQ). They are used as starting products for vulcanizates with exceptionally high resistance to fuels, oils and chemica

Polymeric siloxanes consist of repeating Si-O units. With the phenyl-methyl-polymer siloxanes, organic groups (phenyl, methyl) are bound to the siloxane units (Si-O).

Due to the higher binding force of the atoms in the siloxane chain (Si-O-Si-O- ...) compared to the binding force in an organic polymer (carbon chains), unique physical, chemical and electrical properties result.

The chemical structure of the siloxanes allows them to be manufactured in a variety of forms. For example as a liquid, gel, elastomer (rubber) and resin (solid). Due to their many variations of their Si-O structures and the organic buildup, they have extraordinary properties.

Phenyl-methyl-siloxanes have a particularly good chemical stability and are available for applications with an operating temperature between -20 ° C and 245 ° C.

Phenyl-methyl-siloxanes are used as lubricants, transformer oils, release agents, hydraulic media, defoamers and as diffusion pump oils.
