Polyphosphoric Acid (PPA) Supplier in Malaysia
- Also known as
- PPA
- Superphosphoric Acid
- Condensed Phosphoric Acid
Polyphosphoric acid supplier in Malaysia for bitumen modification, organic synthesis and industrial process work. Also called PPA, superphosphoric acid and condensed phosphoric acid, it is a viscous, hygroscopic mixture of condensed phosphoric acids rather than a single compound.
Commercial strength is quoted as H3PO4 equivalent or P2O5 content, with common trade designations such as 105% and higher 115% class material. Grade choice also turns on water content, viscosity, colour and metal impurities for the intended process.
Road and binder formulators use PPA as a bitumen modifier to raise softening point and improve rutting resistance. Chemical manufacturers use it as a dehydrating, condensing, cyclisation and acylation agent, including fine-chemical and selected metal-treatment routes. It is not orthophosphoric acid.
Send the required H3PO4 equivalent or P2O5 content, application, impurity limits, quantity and delivery location with your enquiry. Availability, packing and documentation are confirmed with the quotation.

Polyphosphoric Acid 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 |
|---|---|---|---|---|
| Polyphosphoric acid 105% (H3PO4 equivalent) | viscous liquid | — | Bitumen and asphalt modification where a standard commercial PPA grade is specified for softening-point and rutting-resistance work. | Confirm the required pack format with the quotation. |
| Higher-strength polyphosphoric acid (115% class) | viscous liquid | — | Organic synthesis and process chemistry that call for a higher P2O5 equivalent or stronger dehydrating and condensing performance. | Confirm the required pack format with the quotation. |
| Low-impurity polyphosphoric acid | viscous liquid | — | Fine-chemical, pharmaceutical intermediate and catalyst-preparation work where colour, iron and heavy-metal limits matter to the process. | Confirm the required pack format with the quotation. |

Polyphosphoric Acid applications
Safety and handling
Keep sealed and protect from moisture. Polyphosphoric acid is strongly hygroscopic. Follow the safety information supplied with the quoted grade. Supply is subject to applicable requirements.
Common questions about polyphosphoric acid
Is polyphosphoric acid the same as phosphoric acid?
No. Polyphosphoric acid is a mixture of condensed phosphoric acids traded as PPA, while phosphoric acid (orthophosphoric acid) is the monomeric acid. They have different handling profiles and typical applications, so each should be enquired for under its own product identity.
What does a polyphosphoric acid grade such as 105% mean?
Commercial grades are commonly designated by H3PO4 equivalent, for example 105% or 115% class material, or by P2O5 content. The figure reflects the condensed strength rather than a single pure compound, so state the equivalent your process or bitumen specification requires.
Can polyphosphoric acid be used as a bitumen modifier?
Yes. PPA is widely used to modify bitumen and asphalt for road paving, improving softening point and rutting resistance when dosage and binder compatibility are set for the project. State the bitumen grade, target dosage and any storage-stability needs in the enquiry.
Which details matter for organic synthesis grades?
Synthesis buyers usually specify P2O5 equivalent or H3PO4 equivalent, water content, viscosity and impurity limits such as iron and heavy metals. Include the reaction type and any colour or residual-acid constraints so a suitable grade can be matched.
What packing is available for polyphosphoric acid?
Industrial buyers commonly request drum or IBC supply for this viscous liquid. Preferred pack format is confirmed with the quotation against the grade, quantity and handling constraints at the delivery point.
How do I request a polyphosphoric acid price?
Provide the grade equivalent, application, target specification, quantity and delivery location. Mention documentation needs and preferred packing so the quotation can cover the full commercial requirement.
