Description
MPEG is one of the raw materials for the production of polycarboxylate high performance water reducer products. which is made with the most advanced ethoxylation technology and production unit. While preparing water-reducing agents, abrupt polymerization and viscosity rising would never happpen.
MPEG (Methoxy Polyethylene Glycols)
Chemical Name: Methoxy Polyethylene Glycols
Chemical Structure:CH3O(CH2CH2O)nH
Properties and Uses
MPEG is used to produce polycarboxylic acid water reducing agent in thermal polymerization method, the environmental-friendly products feature a small dosage and good effect upon reducing water and strengthening. The final wate-reduce agent shows a great durability and rustproof against steel bar. These products are suitable to formulate commercial concrete with great property and strength(above C60)either at constuction site or after a long-distant delivery.
