HPEG Polycarboxylic monomer

      HPEG also known as Methylallylpoly Oxygenethene Ether, Methylallyl Polyoxyethylene Ether, Polycarboxylate Superplasticizer Monomer.

      This product is non-toxic, non-irritating, non-flammable, and easily soluble in water and various organic solvents. It is a stable high polymer compound. It has active functional groups and can react with active hydrogen or double bonds. It can be used for modifying silicone oil grafting and dispersing agents for polymer materials.

      It is a very important monomer raw material for the production of high-performance polycarboxylate superplasticizers. It has the characteristics of high reaction activity and high retention rate of double bonds.

Dilute this product directly with water to the required ratio, then mix it with unsaturated fatty acids. Under the condition of a redox initiation system, polycarboxylate superplasticizers can be synthesized at a temperature below 60℃.

      Specification:

Appearance: White/Light Yellow Solid

Hydroxyl Value (mgkOH/g):21-26

pH value: 8.0-11.0

Degree of unsaturation (mol/kg): ≥0.390

      Advantages:

1.Polycarboxylate superplasticizers synthesized with this product exhibit higher water reduction rate, better slump retention, excellent early strength development, as well as low alkali content, low foam, and low energy consumption.

2. A third monomer is introduced: it has better molecular weight regulation function, which ensures uniform molecular weight distribution of the synthesized superplasticizer, leading to good workability and low viscosity of concrete.

3.The relatively high degree of unsaturation ensures a higher effective content of the superplasticizer synthesized in the later stage, providing the most favorable guarantee for high water reduction rate and excellent slump retention.
