For antiblock, functional masterbatch, compounding and film-additive masterbatch plants. Granular and low-iron high-purity silica improve feeding, dispersion, loading and the functional stability of the downstream film.

Two granular grades aimed at stable feeding and dust control in masterbatch production, plus a low-iron high-purity powder route for customers with tighter downstream appearance requirements.
We publish the selection logic, not the numbers. Data sheets are issued per enquiry so the figures match the current supplier revision and your application.
Typical values for orientation only, not a specification. The current supplier technical data sheet governs for quotation, COA and customer testing — request it for the grade you are evaluating.
| 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 |
CENSIL 165GR and 185GR come first for granular feeding and masterbatch dispersion; CENSIL 779 is the supplementary low-iron, high-purity route where downstream appearance requirements are tighter. Confirm resin, equipment, loading and target film properties first.
Liquid vitamins and choline that will not stay a free-flowing powder; premix caking in store.
Seasoning and beverage powders bridging in the hopper or setting hard on the shelf.
Paste that separates, thins or loses its structure between batches.
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.
