What does silica do in functional masterbatch dispersion?
- Carry antiblock and anti-adhesion functions stably into PE, PP and PET carrier-resin masterbatch.
- Granular material improves feeding stability and reduces dust-management difficulty.
- Judge suitability for production through dispersion, screen-pack pressure and downstream film performance.
Who is this track for?
- Antiblock, anti-adhesion and functional masterbatch manufacturers.
- Compounding plants, film-additive masterbatch producers and plastic-additive blenders.
- Masterbatch channels serving film, packaging and engineering-plastics customers.
Which CENSIL grades are used for functional masterbatch dispersion?
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.
Granular, for masterbatch production where feeding stability and dust control drive the choice more than fineness does.
TDS · specifications · COA on requestThe granular grade at a higher surface-area position, for masterbatch work that needs more functional loading from the same feeding behaviour.
TDS · specifications · COA on requestThe same low-iron platform, aimed at tighter downstream appearance requirements — and the powder route for masterbatch plants whose customers judge the film by eye.

| 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 |
Which reference brands do customers benchmark against?
Trademarks belong to their respective owners and are named for orientation only. No equivalence is claimed; fit is confirmed by your own trial.
Which grade should you start with?
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.
