Sodium Hexametaphosphate (SHMP 68%) | Dispersant

Sodium Hexametaphosphate

Sodium Hexametaphosphate (SHMP) is a versatile inorganic polyphosphate widely recognized for its exceptional chelating and dispersing capabilities. Featuring a high P2O5 content (≥68.0%), it serves as a highly effective water reducer and dispersant in refractory castables and specific concrete admixtures, greatly enhancing fluidity and structural density. Furthermore, its outstanding ability to soften water makes it a premium scale inhibitor for industrial water treatment systems and an essential additive in ceramic manufacturing and detergent formulations.

Applications:

Concrete & Refractory Industry: Acts as a highly effective dispersant, water reducer, and set retarder. It is extensively used in refractory castables and special concrete formulations to significantly reduce water demand, improve mixture fluidity, and increase the density and strength of the final structure.

Water Treatment: Functions as a premium water softener and scale inhibitor. It effectively chelates metal ions (like calcium and magnesium) to prevent scale formation and corrosion in industrial cooling water systems, boilers, and pipelines.

Ceramics & Mining: Serves as an excellent deflocculant and viscosity modifier in ceramic slip preparation, and as a specialized flotation agent in mineral processing.

Detergents & Cleaning: Used as a crucial auxiliary agent in soap and detergent manufacturing to prevent soap scum formation, soften water, and enhance overall cleaning efficiency.

Safety & Handling:

Precautions: This product is non-toxic but may cause mild irritation to the skin, eyes, and respiratory tract upon prolonged contact. Ensure good ventilation and wear standard personal protective equipment (PPE) such as dust masks and gloves during operation.

Packaging & Storage:

Standard Packaging: 25kg PP woven bags with PE inner liner, or 1000kg Jumbo bags.

Storage Recommendations: Strongly hygroscopic (easily absorbs moisture from the air). Must be stored in a cool, dry, and well-ventilated indoor warehouse. Ensure packaging is tightly sealed after each use to prevent caking and deliquescence.

Shelf Life: 24 months (under strictly dry and sealed conditions).
