Dimethyl Fluid (DMF).
Synonym: Polydimethyl Siloxane, Polydimethyl Silicone Fluid.
Chemical Structure
Introduction
SiSiB® MF2010 is a silicone fluid with a dimethylpolysiloxane structure. It is a synthetic oil which does not exist in nature. It is composed of organic methyl groups and inorganic siloxane bonds (Si-O-Si). Siloxane bonds also make up such highly heat-resistant materials as glass and quartz. SiSiB® MF2010 has numerous unique properties not found in conventional mineral oils or synthetic oils. Products are available in viscosities ranging from water-like, free-flowing fluids to syrup-like fluids.
SiSiB® MF2010-12500 is a 100% polydimethylsiloxane of viscosity 12500cSt.

Applications
As a release agent.
Used purely or as a part of a compounded formula SiSiB® MF2010 provides a non-toxic, non-carbonizing mould release for rubber, plastics and metal die-castings.
As an Anti-Foam agent.
Very small quantities of the fluid are very effective as a foam control agent, especially in non-aqueous systems.
As a mechanical fluid.
The very high viscosity-index, the thermal and chemical stability, shear-breakdown resistance and the rubber compatibility as well as the compressibility make this fluid outstanding for mechanical and hydraulic uses.
As a lubricant.
The fluid provides excellent lubricating properties for most plastic and elastomeric surfaces. Lubricity with metals depends upon the possible combinations such as P.T.F.E., MoS2 and other lubricity improvers.
In polishes and chemical specialties.
Silicone oil is used in most automobile and furniture polishes for its ease of application, high gloss with a minimum rubbing and durable water repellent film.
In electrical and electronic equipment.
Because of the excellent dielectric properties silicone oil is widely used as an insulating and damping fluid.
