| Name | Naphthalene Superplasticizer |
| Chemical Name | Poly Sodium Naphthalene Sulfonate |
| CAS NO. | 9084-06-4 |
| EINECS.No. | 200-838-9 |
| Application | 1. Widely used in precast & ready-mixed concrete, armored concrete and pre-stressed reinforced concrete in key construction projects such as dam and port construction, road building & town planning projects and dwelling erections etc. 2. Suitable for preparation of early-strength, high-strength, high-anti-filtration and selfsealing&pumpable concrete. 3. Used for and widely for self-cured, vapor-cured concrete and its formulations. At the early stage of application, extremely prominent effects are shown. As the result, the modulus and site utilization can be drastically, the procedure of vapor cure is omitted in peakheat summer days. Statistically 40-60 metric tons of coal will be preserved when a metric ton of the material is consumed. 4. Compatible with Portland cement, normal Portland cement, Portland slag cement, flyash cement and Portland pozzolanic cement etc. |
