The first question is what is HPEG.
HPEG is the most common type of monomer. Monomer is the most important raw material for the production of polycarboxylic acid superplasticizer.
There are many types of monomers, in addition to HPEG, there are TPEG, LPEG, MPEG, and VPEG that is often mentioned in the industry. They are different because of the different alcohols added in the process of synthesizing monomers from raw material EO.
In addition, another important indicator of monomers is molecular weight. The most common molecular weight is 2400 molecular weight. Dongke’s monomer products have molecular weights
HPEG F-1088 2400 molecular weight
TPEG F-108 2400 molecular weight
TPEG modified F-1089 2800 molecular weight
TPEG modified F-2066 3000 molecular weight
LPEG F-2089 3600 molecular weight
Of course, the R&D department of our Dongke Group can customize any molecular weight according to customer needs to meet customer’s individual requirements
It is generally believed that the higher the molecular weight of the monomer, the better the water reduction rate and slump retention performance of the produced polycarboxylic acid superplasticizer. However, the higher the molecular weight, the higher the requirements for transportation, because high molecular weight monomers tend to self-polymerize during long-distance transportation, which affects product performance.
The polycarboxylic acid superplasticizer synthesized by different types of monomers has different effects.
The HPEG F-1088 produced by Dongke, the synthetic water reducing agent has a very good water reducing effect, and the water reducing agent is as high as 25-30%
TPEG F-108, the synthetic water reducing agent has very good slump retention performance.
TPEG modified and LPEG, synthetic water reducers, have both water reducing and slump retention properties, and the cost is very high.
Of course, the suitability of the monomer must be confirmed by testing.
Dongke Group has been committed to monomer production for 15 years and is one of the best brands in China. Its products are widely exported to Russia, the Middle East, Europe, Southeast Asia and other places. If you need monomer, you need HPEG 2400, please feel free to contact us.
