Silicone-Free Antifoam
Silicone-free antifoam — an organic (polyacrylate-type) antifoam giving excellent air release, the choice for turbine oils and applications where silicone is undesirable.
The antifoam for excellent air release
When air release is critical, silicone-free antifoam wins. Organic antifoams control foam while allowing entrained air to escape fast — essential for turbine and demanding oils.
Silicone-free antifoam is an organic (typically polyacrylate-type) antifoam that controls foam while giving excellent air release. Because silicone antifoam can slow air release at higher doses, silicone-free types are preferred where releasing entrained air fast is critical — above all in turbine oils, and in other demanding oils where trapped air must escape quickly. They are also used where silicone is undesirable for downstream or process reasons. Foam control is gentler than powerful silicone, so dosing is tuned to the application. It is part of the antifoam agents range and is central to turbine oil formulation.
Silicone-Free Antifoam — typical properties
Representative typical values for silicone-free antifoam. Indicative only — exact values vary by grade and are confirmed on the TDS and batch COA.
| Property | Typical Value | Method / Note |
|---|---|---|
| Appearance | Clear to hazy liquid | Grade-dependent |
| Active type | Organic (polyacrylate-type) | Silicone-free |
| Air release | Excellent | Key benefit |
| Foam control | Effective (gentler than silicone) | Tuned dosing |
| Silicone content | None | Silicone-free |
| Flash point (COC) | > ~150 °C | ASTM D92 |
| Function | Antifoam | Air-release priority |
Typical values for guidance only — not a specification. Request the TDS for the specific grade you need; the COA reports actual measured values for your batch.
