CENSIL 185P is a precipitated silica powder in Sensilchem's film antiblock & masterbatch family. A conventional precipitated comparison route for film antiblock. Run it beside 773 or 779 when cost position has to be part of the decision. It is quoted on the plastic film antiblock track. Specifications, the technical data sheet and a COA are issued per enquiry; the fit is confirmed on your own line.
Particles that create just enough surface microroughness to stop film blocking — without pushing haze past what the packaging allows.
The low-iron, high-purity route where film optics matter. Usually the first antiblock candidate for clear packaging film and the masterbatch that feeds it.
The same low-iron platform, aimed at tighter downstream appearance requirements — and the powder route for masterbatch plants whose customers judge the film by eye.
Granular, for masterbatch production where feeding stability and dust control drive the choice more than fineness does.
The granular grade at a higher surface-area position, for masterbatch work that needs more functional loading from the same feeding behaviour.
Run CENSIL 185P beside the material you use now, in your own system at the same loading, and read the dimensions below. We send a short test plan with every sample set.
| Test dimension | What to watch | What it tells you |
|---|---|---|
| Antiblock performance | Interlayer separation and opening force | Tells you the core performance |
| Haze and clarity | Change in film optical appearance | Tells you packaging appearance fit |
| Coefficient of friction | Slip, conveying and converting behaviour | Tells you downstream efficiency |
| Dispersion | Gels, fish-eyes or streaks | Tells you film quality stability |
| Process fit | Extrusion, screen pack and bubble stability | Tells you the line-introduction risk |

Technical data sheet at the current supplier revision with the test method behind each figure, a specification sheet, a certificate of analysis for every lot, SDS / MSDS and a use statement for the destination market. Sensilchem does not publish specification tables on the website; request the set by email and it arrives matched to your application.
The material you use now, the formulation or resin, the equipment and the target you need to hit. That is enough for us to say whether we have something worth testing.
