Performance characteristics and applications of oligodimethylsiloxanes

The performance characteristics of oligodimethylsiloxanes are given in references (Skorokhodov 1978). However, a review of these properties in combination with general information about their applications and the nomenclature of technical oligodimethylsiloxane materials seems appropriate and may be useful for many specialists. 

Taking this into account, this monograph gives information about the performance characteristics, applications and nomenclature of these materials in the form of a table (Table 15.1) (Sobolevsky 1985). The temperature performance characteristics are necessary to determine the accept- 

Oligodimethylsiloxanes (PMS) and oligodimethyl(methyl)siloxanes (PMS-b) ( b stands for branched structure ) have a wide range of properties depending on the composition, structure and molecular weight. The main characteristic which determines their fields of application is kinematic viscosity. Its value is found in the brand of PMS and PMS-b liquids. 

The oligomers of this oligoorganosiloxane group, given in Table 15.1, are classified according to their applications in the following way. 

PMS-1 - PMS-2 liquids are used as cooling and damping liquids in various devices below 60 °C PMS-10 - PMS-1000 are used as damping and hydraulic liquids in devices and mechanisms, as well as dispersion media for plastic lubricants, mineral butters and pastes, which have performed well in the stop valves of gas pipelines.
