530P Polycarboxylate Superplasticizer Powder
34% water reduction powder superplasticizer for ordinary Portland cement dry-mix formulations — delivering improved flowability, lower water demand, and stable batch-to-batch performance.
Overview
530P is a third-generation polycarboxylate-based (PCE) superplasticizer supplied as a free-flowing powder. It is specifically developed for ordinary Portland cement (OPC) dry-mix formulations, providing high water reduction efficiency while maintaining good workability and flow performance.
Compared with liquid superplasticizers, powder PCE eliminates additional water transportation, reduces freezing risks during overseas shipment, and simplifies storage and dosing for dry-mix mortar manufacturers.
Why Formulators Choose 530P
- ● 34% water reduction performance — enables lower water-to-cement ratios while maintaining required flowability and mechanical performance.
- ● Easy powder blending — designed for direct addition into dry-mix formulations without changing existing production processes.
- ● Lower logistics cost — no water content transportation, no liquid drum handling, and reduced freeze protection requirements.
- ● Stable dispersion performance — optimized particle distribution supports uniform mixing and consistent mortar quality.
- ● Advanced PCE molecular structure — comb-shaped polymer technology provides steric hindrance and efficient cement particle dispersion.

Recommended Applications
- ● Cement-based self-leveling compounds — improves flowability and reduces water demand.
- ● Waterproofing mortar and floor leveling mortar — supports dense structure and improved durability.
- ● Non-shrink grout materials — improves workability and packing density.
- ● Cementitious waterproofing systems — helps achieve low permeability formulations.
- ● General construction mortars — suitable for various OPC-based dry-mix applications.
How 530P Works
530P improves cement particle dispersion through the combination of electrostatic repulsion and steric hindrance created by its polycarboxylate molecular structure.
The polymer backbone adsorbs onto cement particle surfaces, while side chains extend into the surrounding water phase, creating a protective hydration layer. This reduces particle agglomeration, lowers internal friction, and allows better flow performance with reduced water content.

Frequently Asked Questions
Is 530P suitable for all Portland cement systems?
530P is optimized for ordinary Portland cement systems. For different cement chemistry, such as sulphoaluminate cement or gypsum-based systems, selecting the correct PCE grade is recommended to achieve stable compatibility.
What are the advantages of powder PCE compared with liquid superplasticizer?
Powder PCE reduces transportation of unnecessary water, avoids freezing problems during cold-weather shipment, simplifies warehouse management, and provides better suitability for dry-mix mortar production.
What dosage should be used for 530P?
The optimum dosage depends on cement type, formulation design, target flow, and strength requirements. Laboratory trials are recommended before commercial production.
Can 530P be supplied with OEM packaging?
Yes. OEM packaging, private labeling, and customized supply solutions are available according to customer requirements.
Do you provide COA and MSDS documents?
Yes. COA, MSDS, technical data sheets, and export documentation can be provided for customer evaluation and approval.
