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.
