Seller informationVisit store
HPEG is a kind of main raw material (polycarboxylate ether monomer) for producing high performance water reducing type and slump retention type polycarboxylate superplasticizer, it is produced with methallyl alcohol and ethylene epoxide as main raw material.
Polycarboxylic acid high-performance water reducer has good comprehensive technical performance advantages and environmental protection characteristics, which meets the needs of modern concrete engineering. Therefore, polycarboxylic acid based high-performance water reducer is gradually becoming the preferred admixture for preparing high-performance concrete.
Compared with the traditional concrete water reducer, like Lignosulphonate based water reducer, Sulphonated naphthalene water reducer(SNF), JLY series Polycarboxylate superplasticizer has the outstanding advantage as below:
1. Low dosage
2. Excellent water reducing rate over 30%
3. Obvious reinforcement on Concrete strength
4. Good compatibility with Cement
5. Superior performance on Concrete slump retention
6. Eco-friendly water reducing agent, No pollution during production.
