TPEG-2400 Polycarboxylate superplasticizer polyether monomer
■ CH2=C(CH3)CH2CH2O(CH2CH2O)nH, n=10~60
■ TPEG-2400 is a polyoxyethylene isopentenyl ether with molecular weight 2400.It’s produced by isopentenol and ethylene epoxide as main raw material.
■ This product is the main raw material for high performance polycarboxylate superplasticizer
■ The water reducer from this material(TPEG-2400) has good adaptability to cements.
■ Compared with other polycarboxylate material, the production cost of water reducer from this material is greatly reduced.
■ The water reducing rate of the water reducer (solid content 22%) from this material amounts to 30% under 1.1% concrete addition.
■ The water reducer from this material is characterized by early strength,high-strength. The early strength and 28 days’strength of the concrete is greatly improved, compressive strength ratio %: 1 Day≥180; 7 Days≥170; 28 Days≥150.
■ The water reducer from this material has high durability,can efficiently reduce the water/gel ratio, enhance durability, reduce risk of shrinkage and creep.
■ The water reducer from this material has less slump loss, which grows initially without compromising strength, it also has sustained release effect, slump retention is ≥190 mm.
■ The water reducer from this material is environment friendly, chloride ion is no more than 0.1%, comply with the ISO 14000 international environment protection management standard.
PCE made from TPEG-2400 can be used to produce high performance, high strength commercial concrete at work site or long-distant convey.
