CENSIL 185GR is a granular precipitated silica in Sensilchem's film antiblock & masterbatch family. The granular grade at a higher surface-area position, for masterbatch work that needs more functional loading from the same feeding behaviour. It is quoted on the functional masterbatch dispersion 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.
A conventional precipitated comparison route for film antiblock. Run it beside 773 or 779 when cost position has to be part of the decision.
Granular, for masterbatch production where feeding stability and dust control drive the choice more than fineness does.
Run CENSIL 185GR 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 |
|---|---|---|
| Feeding and dust | Feed stability and dust control | Tells you plant operability |
| Masterbatch dispersion | Agglomerates, specks or uneven dispersion | Tells you downstream appearance |
| Screen-pack pressure | Melt filter pressure rise | Tells you extrusion stability |
| Loading | Whether processing holds at the target loading | Tells you commercial viability |
| Downstream film | Opening, haze, clarity, coefficient of friction | Tells you end-application value |

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.
