Silicone Oil (PDMS) Supplier in Malaysia
- Also known as
- Polydimethylsiloxane
- PDMS
- Dimethicone
- Silicone Fluid
ChemTrade supplies silicone oil to industrial buyers across Malaysia. It is polydimethylsiloxane, ordered as PDMS, silicone fluid or dimethicone. Send the required viscosity, quantity and packing with the enquiry.
Viscosity is the specification, and it is the one figure to give us. We carry the standard ladder from 50 and 100 cSt through 350 and 1000 cSt up to 12,500 and 60,000 cSt. The chemistry is identical across the range: what changes is how thin it is, how far it spreads and how well it stays where you put it.
Thin grades wet and spread, which suits mould release, spin finishes and insulating fluid. Heavy grades stay put, which is what a damping fluid, a textile softener or a polish base needs. Tell us the application if you are not sure which end of the range you want.
Silicone oil is odourless, insoluble in water and thermally stable across a wide temperature range. Flash points run above 300 °C, so it is not classified as a flammable liquid and is not regulated as dangerous goods for transport. Ask for the specification and the safety data sheet with your quote.

Silicone Oil grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Silicone oil 50 and 100 cSt | thin, clear liquid | 50 to 100 cSt | Wets and spreads readily, which is what a release film needs. Mould release on plastic and rubber, spin finish and thread lubricant in textiles, electrical insulating fluid, and the carrier grades in personal care. | 200 kg drum |
| Silicone oil 350 cSt | clear liquid | 350 cSt | The general purpose middle of the range. Heat transfer fluid in oil baths and jacketed vessels where a mineral oil would carbonise, general lubrication, and the base for silicone defoamer blends. | 190 or 200 kg drum |
| Silicone oil 1000 cSt | clear, viscous liquid | 1000 cSt | The volume grade, and the one most often asked for by name. Polish and car care formulation, rubber and plastic release, lubrication of plastic against metal, and defoaming. | 190 or 200 kg drum |
| Silicone oil 12,500 and 60,000 cSt | clear, very viscous liquid | 12,500 to 60,000 cSt | Heavy grades that stay where they are put rather than running off. Damping fluid in instruments and dashpots, textile softener base, and lubrication of slow moving or heavily loaded surfaces. | 190 or 200 kg drum |

Silicone Oil applications
Safety and handling
Store sealed in a cool, dry place out of direct sunlight. Silicone oil is inert and will not attack a steel drum, so shelf life is long and stock can be held. The handling point that catches people is surface tension: at around 21 mN/m it creeps, and a film will spread from a spill or a wiped hand onto anything nearby, after which paint, ink and adhesive will not key to that surface. Keep it away from paint and print areas, wipe spills promptly because they make a floor slippery, and wear gloves and safety glasses when decanting.
Common questions about silicone oil
Which viscosity should I order?
Settle this first, because silicone oil is the same chemistry at every grade and viscosity is the only thing that changes. Thin grades at 50 to 100 cSt wet and spread, so they suit release films, spin finishes and insulating fluid. Mid grades around 350 cSt are the general purpose choice for heat transfer and lubrication, 1000 cSt is the volume grade for polish, release and defoaming, and 12,500 to 60,000 cSt stay put where a thin oil would run off. Tell us the application and we will name the grade.
Is silicone oil flammable, and is it a dangerous good?
No on both counts across the grades we supply. Flash points run above 300 °C, well clear of the threshold for a flammable liquid, and straight silicone oil is not classified as hazardous or regulated as dangerous goods for transport, so there is no UN number and no placarding. It will still burn if you hold it in a fire, so treat it as a combustible material for storage. Very low viscosity fluids below 10 cSt are a different case and we would flag that if you asked for one.
Is silicone oil the same as PDMS or dimethicone?
Yes, the same material under different names. Polydimethylsiloxane is the chemical name, PDMS the abbreviation, dimethicone the INCI name used on cosmetic labels, dimethylpolysiloxane the older form, and E900 the food additive number. Order it by whichever name your specification uses, but give us the viscosity with it, because the name says nothing about the grade.
Can you supply food grade or cosmetic grade?
Ask and we will source against the specification. What we hold is industrial grade for release, lubrication, heat transfer and defoaming, while food and cosmetic use call for material supplied against the E900 additive specification or an INCI dimethicone declaration with documentation to match. Tell us the grade, the viscosity and what your audit or product registration needs, and we will quote against that rather than send industrial material with the wrong paperwork.
What packing and quantities do you supply?
Drums are the standard fill, at 190 kg or 200 kg depending on origin, and we hold Chinese and German material. Smaller packing is decanted to order. We work with several producers, so if you need a viscosity or a pack size that is not on this page it is worth asking rather than assuming.
How is it priced?
Price depends on viscosity as much as on the market, and the heavy grades are not the same money as the thin ones. Send the grade and the quantity and we will come back with a current price and a validity period against it, rather than publish a figure that would be wrong for most enquiries.
