Polycarboxylate Ether Monomer

Polycarboxylate Ether Monomer – High-Performance PCE Raw Material from EverStar Group

When you're sourcing the backbone of modern concrete admixtures, you need more than just another chemical supplier. EverStar Group delivers Polycarboxylate Ether Monomer with factory-direct reliability backed by 13 years of manufacturing excellence. Our monomer features a molecular weight of approximately 2400 g/mol, unsaturation ≥0.35 mmol/g, and solid content ≥98%, ensuring predictable polymerization performance every time. With over 5,000 tons of on-site inventory and 99.5% on-time delivery to 50+ countries, we eliminate supply chain uncertainty. Our in-house R&D lab supports 24-hour custom formulation, while EU REACH compliance guarantees international quality standards. This product represents the industry benchmark for price-performance ratio—your most cost-effective path to synthesizing high-water-reduction PCE superplasticizers.

What Makes Our Polycarboxylate Ether Monomer Your Best Choice?

Our monomer stands out in three basic ways.

First, prevalent specialized parameters. You get white to off-white pieces with hydroxyl esteem absolutely controlled at 22-28 mg KOH/g and pH extend 5.0-7.0 in 5% fluid arrangement. This tight detail window implies your polymerization responses stay steady clump after batch.

Second, unmatched generation solidness. Our robotized fabricating lines create fabric with unsaturation ≥0.35 mmol/g—the tall twofold bond maintenance you require for most extreme water-reducing proficiency. We keep up strict dampness control underneath 0.2% to anticipate caking amid capacity and transport.

Third, real-world application flexibility. When you synthesize PCE with our monomer utilizing standard acrylic corrosive proportions, you'll accomplish 25-35% water diminishment. Your concrete keeps up workable droop for 1-2 hour transport windows—perfect for urban ready-mix operations.

How You Can Apply This Monomer?

For high-rise concrete pumping ventures, your synthesized PCE diminishes plastic thickness drastically. Concrete streams easily through channels to statures past 300 meters without blockage risks.

In precast concrete generation, you'll appreciate quicker form turnover. The monomer empowers early quality improvement whereas keeping up tall water reduction—your plant yield increments without compromising quality.

For self-compacting concrete Applications, the coming about PCE conveys extraordinary flowability with zero isolation. Your concrete fills thick fortification zones absolutely beneath gravity, indeed amid long-distance transport in hot weather.

The comb-like atomic structure gives you exact control. Alter side-chain length and thickness amid polymerization to coordinate particular cement sorts and work location conditions.

Why EverStar Group Stands Behind Every Batch?

Manufacturing scale you can depend on. Our committed bulk capacity tank cultivate holds stock prepared for prompt shipment. Whether you require trial amounts or full holder loads, we react fast.

Quality control that kills shocks. Each clump experiences Gel Saturation Chromatography (GPC) to confirm atomic weight dissemination. We perform Iodine Esteem Titration to affirm unsaturation, Karl Fischer investigation for dampness substance, and hydroxyl esteem testing for polyether chain purity.

Technical bolster that tackles genuine issues. Our chemical engineers give definition direction for any cement sort you experience. Confronting unordinary setting behavior? Require to optimize measurement for nearby totals? We're accessible to troubleshoot.

Compliance you can verify. EU REACH registration means our Polycarboxylate Ether Monomer meets international chemical safety standards. ISO-certified quality management ensures consistency from raw material inspection through final packaging.

Storage and Handling Recommendations

Store your monomer in a cool, ventilated warehouse away from direct sunlight. Heat and UV exposure can trigger unwanted polymerization.

Keep containers tightly sealed to prevent moisture absorption. Even small amounts of water can cause the flakes to cake together.

We add specialized antioxidants during production to maintain stability during transit. Proper storage extends shelf life and preserves the high unsaturation level you paid for.

For optimal polymerization results, bring the monomer to room temperature before use. Cold material may not dissolve uniformly in your reaction vessel.

FAQ

Q: What's the difference between your monomer and TPEG or EPEG types?

A: Our product features excellent reactivity for standard aqueous solution polymerization systems. While EPEG offers vinyl ether bonds for room-temperature reactions, our monomer provides the best balance of performance and cost-effectiveness across the widest range of formulations.

Q: Why does unsaturation matter so much?

A: High unsaturation (≥0.35 mmol/g) means nearly every monomer molecule integrates into your polymer backbone. Lower unsaturation leaves unreacted material that doesn't contribute to water reduction—you waste money and get inconsistent performance.

Q: Can I use this directly in concrete?

A: No. This is a raw material for synthesizing liquid polycarboxylate superplasticizers. You'll polymerize it with acrylic acid and functional monomers in your manufacturing process.

Q: How does molecular weight affect my final PCE product?

A: Our ~2400 MW specification delivers excellent initial water reduction. For extended slump retention in hot climates, you might request custom formulations with higher molecular weight side chains—our R&D team can develop that within 24 hours.

Q: What happens if I overdose the final PCE in concrete?

A: Slight overdosing ≤0.2% extra may extend setting time moderately under proper curing. Beyond 0.2-0.3%, you risk 24-72 hour delays, early strength loss of 5-10%, and reduced 28-day strength. Exceeding 0.3% can cause severe over-retardation and structural failure. Always test dosages in your specific mix design.

Q: Under what conditions can I expect 2-7 hour retardation?

A: At 20-35℃ with ordinary Portland cement and standard dosage rates of 0.03-0.15% (of the synthesized PCE), expect 2-7 hour setting delays. Extreme dosages may extend this to 8 hours. Temperature, cement type, and mixing water all influence actual results.

Q: Does your monomer work with all cement brands?

A: We maintain an extensive application database covering various cement chemistries. Our technical team provides formulation support to optimize compatibility with your local cement suppliers.

Q: What quality documentation do you provide?

A: Each shipment includes a Certificate of Analysis with GPC results, unsaturation testing, moisture content, hydroxyl value, and pH measurements. We also provide REACH compliance documentation and MSDS sheets.
