4. Core Product Characteristics

High Purity & Ultra-Low Impurities: The high-purity Class I product has sodium sulfate content up to 99.0%. Strictly controlled impurities including water-insoluble matter, iron, calcium-magnesium and chloride, far exceeding ordinary industrial standards.
High Whiteness & Premium Appearance: Pure and transparent crystals with no yellow or black particles. The fine and uniform powder will not cause color contamination, ideal for high-end printing & dyeing and glass manufacturing.
Stable Physical & Chemical Properties: Excellent chemical stability, no decomposition or deterioration. The aqueous solution is clear and neutral with extremely low corrosion to production equipment.
Fast Solubility & No Residue: Superior water solubility, dissolves rapidly in water without precipitation or floating impurities, perfectly applicable for precise proportioning processes.

Low Moisture & Long Storage Stability: Ultra-low moisture content keeps the product dry and non-caking under conventional warehouse conditions, maintaining stable quality for long-term storage.

5. Main Application Fields

Printing & Dyeing Industry: Used as dye filler, dyeing auxiliary and color fixing agent to improve dyeing uniformity and color saturation, serving as a core auxiliary material in the textile industry.

Glass Manufacturing Industry: Applied as defoamer and clarifier for daily glass and flat glass to remove bubbles and impurities, improving glass transparency and finished quality.

Daily Chemical & Detergent Industry: Main filling raw material for washing powder and synthetic detergents, improving powder fluidity and anti-caking performance while reducing production costs.

Chemical Industry: Raw material for sodium sulfide, water glass, pigments and various fine chemical additives.

Papermaking Industry: Used as cooking agent and deinking auxiliary to improve pulp performance, paper toughness and flatness.

Other Fields: Feed additives, battery raw materials, metallurgy mineral processing, oilfield chemicals, refrigeration industry and building material auxiliaries.
