China's leading manufacturer of reinforced polypropylene fibers, offering comprehensive fiber solutions.
With years of export experience and service coverage across Asia, the Middle East, Africa, South America, and Europe, we help construction chemical distributors, dry mortar manufacturers, and concrete additive importers source reliable polycarboxylate ether flakes with stable quality and competitive pricing.
Polycarboxylate superplasticizer flakes, also known as PCE flakes, are a solid-form high-range water reducing admixture produced from polycarboxylate ether polymers. Compared with liquid PCE products, flakes are easier to transport, store, and formulate, especially for export markets and powdered construction material systems.
After dissolving in water, PCE flakes provide excellent cement particle dispersion through steric hindrance and electrostatic repulsion, helping reduce water demand while improving workability and mechanical performance.
Michem’s Polycarboxylate Superplasticizer Flakes is is High Water Reduction Type PCE Flake specially designed for C30 and above high-strength, high-performance self-leveling concrete, delivering excellent workability and flow, significantly enhancing concrete strength and durability, while its high water-reduction rate reduces cement usage and maximizes economic benefits.

By choosing the right PCE, you can optimize crack resistance, toughness, and durability across a wide range of concrete projects.
PCE allows for a significant reduction in the water-to-cement ratio in concrete mixes.
PCE contributes to the development of higher compressive and flexural strengths.
One of the primary benefits of PCE is its ability to enhance the workability of concrete.
PCE offers improved control over the setting time ofconcrete.
By choosing the right PCE, you can optimize crack resistance, toughness, and durability across a wide range of concrete projects.
Our polycarboxylate superplasticizer flakes can significantly reduce water demand in cement-based materials, improving strength development and workability at the same time. This makes them ideal for high-performance mortar and concrete applications.
Unlike liquid superplasticizers, PCE flakes are especially suitable for dry mix mortar factories, where powder-form additives are preferred for easier batching, storage, and transportation.
Michem maintains strict quality control during raw material selection, polymerization, drying, and packaging. Each batch is tested for appearance, pH, moisture, water reduction performance, and solubility to ensure stable results.
We support:
Our polycarboxylate superplasticizer flakes plays an irreplaceable role in concrete construction projects due to its superior water reduction rate.
For many importers and manufacturers, polycarboxylate superplasticizer flakes offer practical advantages over liquid PCE:
This makes PCE flakes a preferred option for distributors and dry mortar factories in international markets.
| Comparison criteria | Polycarboxylate Superplasticizer Flakes | Polycarboxylate Superplasticizer Liquid |
|---|---|---|
| Product Formats | Solid tablets / Powder | liquid solution |
| Main ingredients | Primarily naphthalene-based and aliphatic, with a small amount of polycarboxylic acid powder | Primarily polycarboxylic acid-based, with some naphthalene-based liquid products |
| Solid content | ≥98% | 20%~50%（Polycarboxylic acid is typically used at a concentration of around 40%） |
| Manufacturing Process | After synthesis, the material is spray-dried and cut into slices | Directly synthesized into a liquid, without the need for a drying process |
| Mode of transport | Shipped in bags, with no risk of leakage, suitable for long-distance transport | Transportation in drums or tank trucks carries a risk of leakage and involves high long-distance costs |
| Storage Requirements | Just ensure it is sealed and moisture-proof; there are no freeze-thaw issues. | Protection from freezing and direct sunlight is required, and storage conditions are more stringent. |
| Storage period | has a longer shelf life and does not spoil easily | Relatively short and susceptible to temperature fluctuations |
| Directions for Use | Must be dissolved and mixed with water in advance; requires compatible dissolution equipment | Added directly via a metering pump; no dissolution required; highly automated |
| Packaging costs | Low (mainly woven bags / paper bags) | High (High costs associated with cleaning plastic drums and tank trucks) |
| Shipping costs | Low (no dead weight from water, high transport efficiency) | High (contains a large amount of solvent water; a significant portion is non-transportable) |
| Storage space | Small (high solid content; requires less space for the same amount of active ingredient) | Large (large volume of liquid, high storage requirements) |
| Construction dust | There is dust in the air; please take appropriate protective measures. | Dust-free, making the worksite more environmentally friendly |
| Measurement accuracy | Measuring after dissolution makes the results susceptible to variations in dissolution uniformity | Direct liquid measurement for greater accuracy |
| Applicable Scenarios | Long-distance transportation projects, dry-mix mortar, precast components, and applications where on-site mixing of water is not required | Ready-mix concrete batching plants, nearby construction projects, automated batching production lines |
| Core Strengths | High solids content, low storage and transportation costs, long shelf life, and freeze-thaw resistance | Easy to use, dust-free, accurate measurement, and highly adaptable to on-site conditions |
| Core weakness | Requires dissolution equipment; dust is present; uneven dissolution affects the water-reducing effect | Low solid content, high storage and transportation costs, and requires frost protection in winter |

PCE flakes and PCE powder are both solid forms of polycarboxylate superplasticizer. The main difference is physical appearance and handling characteristics. Flakes are often easier to produce and dissolve gradually, while powder may offer finer particle size for some formulations.
Yes. This is one of the most common applications. PCE flakes are widely used in dry mix mortar, tile adhesive, self-leveling mortar, and cement-based repair materials.
Yes, we can provide free or low-cost samples for lab testing, depending on the requested quantity and destination.
Our MOQ can vary depending on packaging and grade, but we support both trial orders and bulk orders for international customers.
Yes. We can offer customized technical parameters based on your formulation, raw materials, and local market requirements.
