Applications & Use Cases
  • Vibration / shock damping and mechanical (dashpot) fluid — liquid-filled gauges, rotary dampers, hydraulic stabilizers
  • Plastics additive — surface slip and anti-block compounded into plastic; high MW migrates slowly for durable slip
  • Non-carbonizing mold release for rubber, plastics and metal die-castings
  • Polish active — a high-viscosity fluid blended for greater depth of gloss
  • Liquid dielectric, antifoam, and persistent lubrication of plastic/rubber parts (not metal-on-metal)

Safety & Handling
Not classified under GHS

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.

Full Description

Silicone Oil 60,000 cSt is a very-high-viscosity grade for vibration and shock damping and for durable, slow-migrating slip and release films. Its high molecular weight and low viscosity-temperature coefficient give stable damping in dashpots and gauges, plastics surface slip and anti-block, polish depth-of-gloss, non-carbonizing mold release, and dielectric and antifoam duty.

Frequently Asked Questions

What does cSt mean in silicone oil?

cSt stands for centistokes, the unit of kinematic viscosity. A 60,000 cSt grade is a high-viscosity dimethicone fluid; higher cSt means thicker, slower-flowing oil. The value specifies flow behavior, not a difference in chemistry.

What is the INCI name for silicone oil 60,000 cSt?

The INCI / common name is Dimethicone, the same designation used across PDMS fluid viscosities. The chemical is polydimethylsiloxane, CAS 9006-65-9, formula (C2H6OSi)n; the 60,000 cSt figure denotes the viscosity grade.

Is 60,000 cSt silicone oil water soluble?

No. Dimethicone is hydrophobic and not soluble in water. It is miscible with many organic and silicone-based solvents and remains a separate phase in aqueous formulations.

How does 60,000 cSt compare to lower grades like 50 cSt?

Both are the same polydimethylsiloxane chemistry; the difference is average chain length and therefore viscosity. A 50 cSt fluid pours thinly while 60,000 cSt is markedly thicker and slower-flowing, suiting it to higher-cling lubrication and damping uses.

How is 60,000 cSt silicone oil supplied in bulk and at what cost?

It is available in bulk packaging such as drums and totes/IBCs. Pricing is volume- and market-dependent, so RawSource provides a quote against your specified grade and quantity rather than a fixed price. A CoA and SDS accompany each shipment.
