Light Brown Poly Naphthalene Sulfonate

We are major manufacturer and exporter of Poly Naphthalene Sulphonate in Weifang, Shandong, China available with following details.

Product uses:
a c Produces the high slump flowing concrete with no loss in strength.
a c Produces low water/cement ratio concrete with high strengths.
a c Ideal for using in high strength concrete, flowing concrete, early strength concrete, precast steam curing concrete, pre-stressed concrete etc. where it is desired to keep the water/ cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation.
a c Be used as basic material to produce others compound admixtures, (such as accelerating and water-reducing admixture, retarding and water-reducing admixture, pumping antifreeze and pumping water-reducing admixture, etc.)
Advantages
1. Substantial improvement in workability without increased water or the risk of segregation. Normal set without retardation, even when overdosed. Improved density and surface finish.
2. High water reducing rate. 40% increase in 28 day strengths. High strengths after 8 hours.
