Polycarboxylate Ether Monomer(EPEG3000)

Description

Polycarboxylate Ether Monomer EPEG is a kind of main raw material (polycarboxylate ether monomer) for producing Polycarboxylate superplasticizer with excellent slump retention and good adaptability.

Products Description

EPEG is produced with vinyl ethers of Diethylene Glycol and ethylene epoxide as main raw materials.

Chemical Formula

CH2=CH-O-CH2-CH2-O-(CH2CH2O)n-H

Technical Principle

Due to the special molecular structure, the space resistance of the polyether side chain is reduced, the swing of the side chain is more free, and the cohension and entanglement of the polyether side chain is improving

Enterprise Quality Standard

Characteristics

1. Polycarboxylate Ether Monomer EPEG formed by the copolymerization of polycarboxylate ether and acrylic acid has good slump storage performance and good adaptability. Synthetic PTFE has good dispersibility and slump retention, strong adaptability and good viscosity reduction effect. Especially suitable for projects with poor quality, high sand content or high concrete requirements.

2. The C4 and C5 macromonomers usually react at 30℃-40℃, and the reaction temperature is very low. The reaction can be completed without heating at room temperature higher than 5℃.

3. The monomer EPEG reaction can be carried out by one-pot method, that is, the prepared droplets are added to the reaction system at one time, and the reaction can be completed by stirring for 30-40 minutes. The synthetic superplasticizer also has excellent performance, which can greatly simplify the production process of the polycarboxylate superplasticizer.

polycarboxylate ether monomer EPEG is an ideal monomer for synthesizing high-performance water reducers. Its direct copolymerization characteristics and long side chain structure can significantly improve the dispersibility and durability of water reducers. When selecting, it is necessary to focus on double bond retention rate, molecular weight and water content, and strictly control storage conditions to ensure activity. It has irreplaceable advantages in high-end fields such as ultra-high strength concrete and pumped concrete.

Packing

Packed in 25 kg plastic woven bags.（The packaging can be customized according to specific requirements.）

Storage And Transportation

Polycarboxylate ether Monomer EPEG is non-toxic, nonflammable and can be shipped as general chemical, stored at dry, ventilated place, away from sunshine and rain.

Shelf validity: one year
