Perlite Supplier in Malaysia: Expanded and Filter Aid Grades
Perlite supplier for filtration, insulation and lightweight construction work in Malaysia. Perlite is an amorphous volcanic glass that expands into a light, white cellular particle when heated, giving an inert low density mineral used across process and building applications.
Expanded grades run from coarse aggregate for concrete, screeds and insulating plaster through to milled filter aid powders selected on cake permeability. Unexpanded perlite ore is also traded as feedstock for expansion and further grading.
Refiners and beverage plants use perlite filter aid to clarify edible oils, syrups, beverages and process water. Insulation contractors use expanded granules as loose fill for cryogenic vessels and cold boxes, and growers use graded material in growing media.
Send the required grade, particle size, application, quantity and delivery location with your enquiry. Availability, pack format, documentation and delivery timing are confirmed with the quotation.

Perlite 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 |
|---|---|---|---|---|
| Expanded perlite, construction grade | lightweight white granules | — | Lightweight concrete, screeds, insulating plaster and insulating board, where low density and non-combustible behaviour matter more than mechanical strength. | Confirm the required pack format with the quotation. |
| Cryogenic and industrial insulation grade | expanded white granules | — | Loose-fill insulation for cryogenic vessels, cold boxes and low temperature pipework, and annular fill in double-walled tanks. | Confirm the required pack format with the quotation. |
| Perlite filter aid | milled white powder | — | Body feed and pre-coat filtration of edible oils, beverages, syrups, process water and pool circuits, with the grade chosen for cake permeability and clarity. | Confirm the required pack format with the quotation. |
| Horticultural perlite | graded white granules | — | Growing media, propagation mixes and hydroponic substrates where aeration, drainage and an inert carrier are required. | Confirm the required pack format with the quotation. |
| Unexpanded perlite ore | crushed raw mineral | — | Feedstock for expansion plants and for further crushing, grinding or grading before use. | Confirm the required pack format with the quotation. |

Perlite applications
Safety and handling
Store dry, under cover and closed, and keep the material free of contamination and moisture pickup. Control airborne dust during handling and transfer, and follow the safety information for the quoted grade.
Common questions about perlite
What is the difference between expanded and unexpanded perlite?
Unexpanded ore is the crushed raw volcanic glass, still dense and grey. Heating drives off its combined water and expands it into a light, white cellular particle, which is the form used in filtration, insulation and lightweight construction. Most industrial enquiries are for expanded material; state which one you need.
Which perlite grade is used as a filter aid?
Filter aid grades are milled expanded perlite, supplied in a range of permeabilities so the cake can be matched to the liquid and the required clarity. Describe the liquid, the filter type and the current aid or grade in use, and the closest match can be proposed.
How does perlite compare with diatomaceous earth in filtration?
Both are inert mineral filter aids used as pre-coat and body feed. Perlite is a lighter expanded glass and is often chosen where lower cake weight or a different permeability profile suits the process. Many plants trial both, so state the current aid and target clarity in the enquiry.
Can perlite be used in lightweight concrete and plaster?
Yes. Expanded coarse and medium grades act as a lightweight aggregate in insulating concrete, screeds, plasters and boards, cutting dead load while keeping the mix non-combustible. Specify the grading and the target mix design so the right aggregate size is quoted.
Is perlite supplied for horticultural growing media?
Horticultural grades are part of the range and are used in growing media, propagation and hydroponics. They are one application among several here, alongside filtration, insulation and construction. State the grade, quantity and pack format required.
What details are needed for a perlite price enquiry?
Provide the grade or application, required particle size or filtration behaviour, quantity and delivery location, plus any documentation and pack format preference. That is enough to return a quotation with a stated validity period.
