Diethylene glycol monovinyl polyethylene glycol ether（HLP-520)

Details

【Product Overview】

Diethylene glycol monovinyl polyethylene glycol ether is polymerized from ethylene glycol vinyl ether and ethylene oxide, with a molecular formula of: CH2=CHOCH2CH2OCH2CH2O(CH2CH2O)nH。 The synthesized polycarboxylate high-performance water reducer has the characteristics of good workability and good workability retention, and is suitable for pumping concrete, self compacting concrete, and concrete that requires long-distance transportation.

【Molecular structure】

【Product Features】

◆ This series of products adopts internationally advanced alkoxylation devices, catalytic processes, and production technologies, with a narrow molecular weight distribution, low diol content, and high double bond retention rate;

◆ High polymerization activity, fast polymerization speed, significantly improving production efficiency;

◆ Ideal copolymers can be formed with unsaturated monomers such as acrylic acid, maleic anhydride, and acrylic ester to prepare high-performance polycarboxylate superplasticizers with different properties;

◆ The synthesized polycarboxylate based high-performance water reducer has the characteristics of good workability and universality in concrete, and has significant effects on concrete with poor sand and gravel quality and high mud content.
