Applications

Concrete Admixtures

  • Polycarboxylate Superplasticizers: Primary macromonomer at 30-50% in PCE production for high-range water reducers, improving slump flow in ready-mix and precast concrete.
  • Self-Compact Flowing Concrete: Enhances passing ability and filling capacity without segregation.

Industrial Formulations

  • Dispersants and Detergents: 5-15% in water-based dispersants for pigment and filler suspension in paints and coatings.
  • Scale Inhibitors: Copolymerized for boiler and cooling water treatments to prevent mineral deposits.

Why Choose Our HPEG 2400?

Our HPEG 2400 is ethoxylated from renewable sources with advanced purification, ensuring low residual allyl alcohol (<0.1%) and consistent EO chain for uniform PCE molecular weight. Admixture producers achieve 25% better slump retention and 20% higher compressive strength at 28 days. Available in technical and customized EO degrees, packaged in 25kg bags or 500kg drums, with ISO 9001 and REACH certifications for sustainable supply.

Frequently Asked Questions (FAQs)

What is HPEG 2400?

HPEG 2400 is Methyl Allyl Alcohol Polyoxyethylene Ether, a macromonomer with CAS 29385-43-1 for PCE superplasticizers. It’s a flaky solid that disperses cement particles for high-performance concrete.

How is HPEG 2400 used in PCE synthesis?

Copolymerize 40-60% with acrylic acid via free radical polymerization at 60-80°C; it provides comb-like structure for steric dispersion and water reduction.

Is HPEG 2400 suitable for eco-friendly concrete?

Yes, its bio-based compatibility reduces cement by 10-15%, lowering carbon footprint while meeting ASTM C494 Type F standards.

What is the shelf life of it?

Stored dry below 30°C, it remains stable for 12-24 months, with no polymerization or degradation.

Can HPEG 2400 replace TPEG in admixtures?

HPEG 2400 offers better slump retention at 1:1 ratios but higher reactivity—pilot tests ensure compatibility.

Does it affect concrete pH?

Its neutral pH (5-7) has minimal impact, maintaining alkalinity for steel passivation in reinforced mixes.

What packaging options are available for it?

We offer 25kg multi-layer bags, 50kg drums, and 1000kg supersacks, all moisture-proof for safe transport.

For PCE recipes, performance data, or custom EO lengths, our admixture experts provide tailored support.
