Dimethicone- ▸ Antifoam / foam-control base oil — the base material for silicone antifoam compounds, incl. food-grade and refinery foam control
- ▸ Tenacious lubricant / release agent for O-rings, gaskets, valves, seals and food-grade freezer chain & cable
- ▸ Polish and coatings additive — blended across viscosities to tune application ease and depth of gloss
- ▸ Electrical insulating / dielectric fluid
- ▸ Personal-care conditioning for skin and hair serums — slip, shine and long-lasting protection
Mid- and high-viscosity polydimethylsiloxane fluids (>= 5 cSt) are reported as not meeting GHS hazard-classification criteria. The grade-specific SDS governs. A full SDS is supplied with every shipment and on request; hazard status is confirmed against the grade-specific SDS.
Silicone Oil 1,000 cSt is the classic antifoam-concentrate base oil: high enough for a tenacious, persistent film yet still able to disperse and emulsify. It is the base material for silicone antifoam compounds and a tenacious release/lubricant for seals, valves and chain, plus a polish and coatings additive, a dielectric fluid and a personal-care conditioner.
Frequently Asked Questions
What is 1,000 cSt silicone fluid used for?
1,000 cSt silicone fluid (dimethicone / PDMS) is the classic antifoam-concentrate base oil, plus a tenacious release/lubricant for seals, valves and chain, a polish and coatings additive, a dielectric fluid and a hair/skin conditioner. It is tenacious yet still dispersible and emulsifiable.
Is 1,000 cSt silicone fluid the same as dimethicone or silicone oil?
Yes — silicone fluid, silicone oil, dimethicone and PDMS all refer to the same linear polydimethylsiloxane (CAS 9006-65-9); 1,000 cSt is the viscosity grade. Because it is a polymer rather than a single molecule, properties are reported per grade rather than as one fixed molecular weight.
Is 1,000 cSt silicone oil flammable?
No. At a flash point of ≥ 315 °C (open cup) the 1,000 cSt grade is not classified as flammable, and mid- to high-viscosity PDMS is not otherwise GHS-classified. Only the volatile sub-5 cSt grades (and discrete volatiles like MM) are flammable. A grade-specific SDS ships with every order.
