Diatomaceous Earth Supplier in Malaysia: Filter Aid and Filler Grades
- Also known as
- Diatomite
- Kieselguhr
- DE
Diatomaceous earth supplier for filtration, filler and absorbent duties across Malaysia. Also traded as diatomite or kieselguhr and abbreviated to DE, it is the amorphous silica skeleton of fossil diatoms, mined, dried and milled into a light porous powder. That open structure is what makes it a filter aid rather than a plain mineral filler.
Filter aid grades are chosen on cake permeability, which is the real buying decision on this product. Natural uncalcined material builds the tightest cake, calcined grades sit in the middle of the ladder, and flux-calcined grades run the fastest flow rates. State the liquid, the filter type and the clarity you have to reach.
Away from filtration, milled grades work as flatting agents in coatings, as anti-block additive in polyolefin film, and as absorbents and dry carriers. Palm oil refiners, breweries, sugar and glucose plants, pool contractors and compounders all buy on permeability or particle grading rather than on one fixed specification.
Enquiries here are for process quantities of milled industrial grades, not garden or animal-use packs. Send the grade or permeability in use, the application, quantity and delivery location. Availability, pack format, documentation and timing are confirmed with the quotation.
- Grade
- natural, calcined, flux-calcined
- Appearance
- fine powder, off-white to light grey; buff, pink or white by grade
Diatomaceous Earth grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Natural (uncalcined) diatomaceous earth | fine off-white to light grey powder | — | Tight, low-permeability filter cakes for polishing duties on beverages, syrups and process liquids where clarity matters more than flow rate, and as a mild abrasive or absorbent base. | Confirm the required pack format with the quotation. |
| Calcined diatomaceous earth filter aid | buff to pink calcined powder | — | Mid-range permeability pre-coat and body feed on edible oil, sugar liquor and general process filtration, which is where most industrial filter aid enquiries land. | Confirm the required pack format with the quotation. |
| Flux-calcined diatomaceous earth filter aid | white to pinkish-white flux-calcined powder | — | Fast flow rates on heavy solids loadings and viscous liquids, selected when cycle time and throughput govern the filtration rather than the finest achievable clarity. | Confirm the required pack format with the quotation. |
| Functional filler grade | milled white to buff powder | — | Flatting and matting agent in paints, lacquers and inks, anti-block additive in polyolefin film, and reinforcing or extending filler in rubber and polymer compounds. | Confirm the required pack format with the quotation. |
| Absorbent and carrier grade | coarse granular powder | — | Liquid absorbent for spills and workshop floors, and a dry carrier or diluent for agrochemical, catalyst and additive formulations that need a free-flowing porous particle. | Confirm the required pack format with the quotation. |

Specifications
| Parameter | Value | Method |
|---|---|---|
| Appearance | fine powder, off-white to light grey as natural material, buff to pink after calcining and near-white when flux-calcined | — |
| Material | amorphous silica skeletal remains of fossil diatoms, mined, dried, milled and classified | — |
| Grade axis | natural, calcined and flux-calcined material sold along a cake permeability ladder rather than as one specification | — |
| Permeability | filter aid grades are ranked by cake permeability in darcy, from slow polishing grades to fast, free-draining grades | — |
| Particle grading | particle size distribution and wet cake density confirmed against the required grade | — |
| Moisture | moisture and loss on ignition confirmed against the required grade | — |
| pH | pH of an aqueous suspension shifts with calcination and any flux used, so it is confirmed against the quoted grade | — |
| Solubility | insoluble in water and inert in most process liquids | — |
| Silica form | calcination changes the mineral form as well as the permeability, so the producer's safety data sheet is the reference for respirable silica content | — |
Diatomaceous Earth applications
Safety and handling
Store dry, covered and closed so the powder stays free-flowing and free of contamination. Handling is dusty, so control airborne dust at transfer and dosing points and use eye protection and a suitable mask. Like any mined mineral it carries a respirable dust exposure, and calcined grades differ from natural ones, so work to the safety data sheet for the grade quoted.
Common questions about diatomaceous earth
Is diatomite the same as diatomaceous earth?
Yes. Diatomite and kieselguhr name the same mined amorphous silica material, and buyers working from older specifications often still write kieselguhr. Filtration practice shortens it to DE. Whichever term the enquiry uses, state the grade or the permeability so it is unambiguous.
What is the difference between natural, calcined and flux-calcined grades?
Heat treatment. Natural material is dried and milled only, giving the tightest cake and the slowest flow. Calcining sinters the particles and opens the cake, and adding a flux before calcining opens it further, which is why flux-calcined grades run the fastest permeabilities. Colour shifts with the treatment as well, so the grade name and not the shade is what an enquiry should state.
How do I choose a filter aid permeability?
Work from the liquid, not from the product name. Describe the solids loading and viscosity, the filter type, the target clarity and the grade you run today, and the closest match on the permeability ladder can be proposed. Most plants confirm the choice with a filtration trial on their own liquid before switching.
Which grade suits edible oil and palm oil filtration?
Post-bleach and polishing filtration in oil refining normally sits in the mid to fast permeability range, because cycle time and cake handling drive the duty. State the press or leaf filter type, the dosing rate you use and the oil being run, and note that diatomaceous earth is the filter aid here, not the bleaching adsorbent.
Is diatomaceous earth used in food and beverage filtration?
Brewing, wine, juice, syrup and sugar plants are among the largest users, with the aid applied as pre-coat and body feed. Grades intended for those duties are specified and documented differently from industrial filler material, so state the intended use and the documentation you need with the enquiry. Supply is subject to applicable requirements.
Is this the same as garden or pet-grade diatomaceous earth?
The underlying mineral is the same family, but supply here is industrial: milled process grades in commercial quantities for filtration, filler, anti-block and absorbent duties. Consumer garden, poultry and pet packs are prepared and labelled for those uses by their own suppliers. Tell us the application and quantity and the enquiry can be answered on that basis.
How does diatomaceous earth compare with perlite as a filter aid?
Both are inert mineral aids used as pre-coat and body feed, and they are often interchangeable on paper but rarely identical in practice. A diatomaceous earth cake is heavier and its permeability ladder is wider, which is why refiners and breweries with a fixed clarity target usually specify it. Trial results on the actual liquid settle the choice.
What details are needed for a diatomaceous earth price enquiry?
Provide the grade or permeability, the application, quantity and delivery location, plus any particle grading, moisture or documentation requirements. Mention your preferred pack format and the timing you are working to so the quotation covers the whole requirement.
