HPEG 2400 Polycarboxylate Superplasticizer Macromonomer

HPEG 2400 Polycarboxylate Superplasticizer Macromonomer is soluble in water and various organic solvents, and is an important raw material for a new generation of carboxylic acid superplasticizer.
The carboxylic acid superplasticizer synthesized using this product has high particle dispersing performance and retention ability, and has many advantages such as high water reduction rate, low cement usage, good reinforcement effect, good durability, stainless steel tendons, and environmental friendliness.
Hpeg Concrete Polycarboxylate Superplasticizer can be used in high-performance, high-strength (above C60) commercial concrete for field mixing and long-distance transportation.
The product adopts the internationally advanced Italian Press external circulation spray ethoxylation addition device and selects high-activity catalytic production technology.
The double bond retention rate is high. When regenerating the water reducing agent, the reaction activity is greatly improved, the product has good appearance, good cohesion and collapse retention, and excellent comprehensive performance.

●significant stable structure in highly acidic or alkaline condition;
●Low-free PEG content;
●Low dioxane and free-EO content 

CharacteristIcs:

1. The water reducer made from HPEG2400 has good adaptability to cements.
2. Compared with other polycarboxylate materials, the production cost of water reducer from HPEG is greatly reduced.
3. The water reducing rate of the water reducer (solid content 22%) from HPEG is amount to 30% under 1.1% concrete addition.
4. The water reducer made from HPEG is characterized by early strength,  high-strength, the early strength  and 28 days’ strength of the concrete is greatly improved, compressive strength ratio %: 1 Day ≥180: 7 Days≥170; 28 Days≥ 150.
5. The water reducer from HPEG has high durability,reduces shrinkage and creep.
6. The water reducer from HPEG has less slump loss, which grows initially, and won’t influence the strength, it also has sustained release effect, slump retention is ≥190 mm.
7. The water reducer from HPEG is environment friendly, chloride ion is not more than 0.1%, comply with the ISO 14000 international environment protection management standard.
