Eighteen grades in six families. Each entry explains what the grade is for and which process problem it addresses. We do not publish specification tables — technical data sheets, specifications and COA are issued per enquiry, at the current supplier revision, with a suggested test plan.
Which form suits you is usually decided by how the material is fed, dosed and handled on your line — not by the chemistry alone.
The default form across most grades — carriers, porous grades, matting silica, hydrophobic silica and antiblock powders.
Free-flowing rounded beads. Lower dust and easier dosing where handling and metering matter more than fineness.
Coarse free-flowing particles used where feeding stability and dust control drive the choice — the GR grades for masterbatch.
Built to take a liquid active onto a dry particle and keep the resulting powder workable. The three grades sit on one absorption gradient, so a trial can move up or down the ladder without changing platform.
The base carrier. Start here when the liquid load is moderate and the real problem is flow and caking rather than raw absorption capacity. Widely used in vitamin and trace-element premixes and as an anti-caking aid in dry food blends.
Used on: Feed Additive Flow & Carrier · Food Powder Flow · Agrochemical Carrier
Request specificationsThe middle route. Takes more liquid than the base grade while keeping the powder free-running — the usual answer when 260P holds the load but the blend stops flowing.
Used on: Feed Additive Flow & Carrier · Agrochemical Carrier
Request specificationsThe high-loading candidate. For choline chloride, organic acids and other demanding liquids where the target loading is the binding constraint and the powder still has to discharge evenly.
Used on: Feed Additive Flow & Carrier · Agrochemical Carrier
Request specificationsHigher pore volume and surface development. These grades carry, stabilise and adsorb rather than simply keeping a powder loose.
A moderate-surface porous route for food powders, brewing stabilisation, toothpaste and flavour carriers. The general-purpose choice when structure matters more than sheer capacity.
Used on: Food Powder Flow · Oral Care Silica · Industrial Fluoride Removal
Request specificationsThe high-surface porous grade. Used in food and oral-care work where adsorption and structure both matter, and it is our preferred base material for fluoride-removal functionalisation screening — as a candidate substrate, not a finished adsorbent.
Used on: Food Powder Flow · Oral Care Silica · Industrial Fluoride Removal
Request specificationsSupplied as a coating matting grade, and used on the fluoride track as a high pore-volume comparison substrate when a screening programme needs a second reference point.
Used on: Industrial Fluoride Removal
Request specificationsWhere appearance, mouthfeel and paste structure decide the outcome.
A fine-powder candidate for oral-care paste structure and appearance work. Selection here is settled on your own paste — cleaning behaviour, viscosity and storage stability — rather than on a datasheet.
Used on: Oral Care Silica
Request specificationsThree surface treatments covering the usual coating systems. The treatment, not the chemistry, is what normally decides which one fits.
Specially treated for waterborne compatibility and refined surfaces. The first grade to test when a waterborne clear has to stay transparent while losing gloss.
Used on: Coating Matting & Rheology
Request specificationsOrganically treated for resin compatibility and easy dispersion. The general-purpose matting route across wood, industrial, UV, plastic and leather coatings.
Used on: Coating Matting & Rheology
Request specificationsUntreated. Balances matting, rheology, anti-settling and cost for industrial, coil, powder and conventional systems where a treated grade is more than the job needs.
Used on: Coating Matting & Rheology
Request specificationsTwo roles: making an oil-based system stable, and turning a liquid defoamer into a powder that still flows.
The hydrophobic, anti-caking route for oil-based defoamer systems. Compatibility with mineral oil, silicone oil, polyether and waterborne systems is always confirmed separately.
Used on: Defoaming & System Stability
Request specificationsA high-absorption candidate for liquid powdering — taking a defoamer oil or liquid active onto a carrier that remains easy to handle and dose.
Used on: Defoaming & System Stability
Request specificationsThe companion high-absorption route, aimed at liquid powdering and powder-system stability work.
Used on: Defoaming & System Stability
Request specificationsParticles 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.
Used on: Plastic Film Antiblock
Request specificationsThe same low-iron platform, aimed at tighter downstream appearance requirements — and the powder route for masterbatch plants whose customers judge the film by eye.
Used on: Plastic Film Antiblock · Functional Masterbatch Dispersion
Request specificationsA conventional precipitated comparison route for film antiblock. Run it beside 773 or 779 when cost position has to be part of the decision.
Used on: Plastic Film Antiblock
Request specificationsGranular, for masterbatch production where feeding stability and dust control drive the choice more than fineness does.
Used on: Functional Masterbatch Dispersion
Request specificationsThe granular grade at a higher surface-area position, for masterbatch work that needs more functional loading from the same feeding behaviour.
Used on: Functional Masterbatch Dispersion
Request specificationsSpecification tables age badly. Figures drift between supplier revisions, test methods differ between catalogues, and a number read out of context says very little about whether a material will work in your formulation.
So we publish the selection logic and issue the data on request. You receive the current revision, the test method behind each figure, and a test plan written around your actual process.
What to expect between the first email and the first container.
Free of charge for qualified enquiries: a main sample plus one or two comparison grades, typically 0.5–2 kg each, with a short test plan. We carry the courier cost on the first sample shipment.
Typical first order is 200 kg to 1 tonne — enough to run a production trial, not a warehouse commitment. Mixed grades on one order are accepted; we will confirm the exact MOQ per grade with the quotation.
Multi-wall paper bags or PE-lined bags on pallets; bulk bags on request. FOB / CIF / DAP as agreed, sea freight from Xiamen or Fuzhou, air or courier for samples and urgent small lots.
Samples ship within a few working days. Production orders are confirmed against stock and production schedule at quotation, with the documentation set (TDS, COA, SDS) issued before shipment.
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.
