    Product Description

    Sodium Naphthalene Formaldehyde is a standard grade superplasticizer which is required for the preparation of concrete pre mix and ready-mix. Its utilization can be noticed in civil construction work and municipality. The unique formulation of this item helps to raise the physical and mechanical properties of concrete and enhances bonding properties of cement. Utilization of non toxic ingredients, exceptional physical stability, high water reducing rate, good strengthening properties, long shelf life, availability in different packaging quantity and balanced ph value are the unique attributes of this item. 

    Noteworthy for its yellowish brown powder form, Sodium Naphthalene Formaldehyde has minimal amount of chloride. It is a good quality water reducing agent with strong dispersion rate. It is capable of enhancing workability of cement by lowering its water content. High concentration level, good compressive strength, less sodium content, required ph value and high purity level are some of its distinctive characteristics. Based in China, we are an eminent manufacturer, exporter and supplier of standard grade Sodium Naphthalene Formaldehyde.
