Core Advantages

High-Purity

Low impurity content reduces interference with downstream processes (such as avoiding uneven dyeing in the textile industry).

Stability

At room temperature, it does not absorb moisture or decompose, making it easy to store and transport.

Solubility

High solubility in water (about 19.5g/100mL at 20 ℃), fast dissolution rate, suitable for rapid reaction scenarios.

Environmentally

The production process complies with environmental standards, the waste can be disposed of in compliance, and there are no toxic residues.

Risk Warning: Low toxicity, but inhalation of dust may irritate the respiratory tract. Skin contact requires timely cleaning; Avoid mixing with strong acids (such as sulfuric acid) to prevent the release of toxic gases.

Protective measures: Wear dust masks, gloves, and protective clothing during operation; Keep the storage area ventilated.

Emergency response: Seek medical attention immediately if ingested, and rinse with plenty of water in case of skin contact.

Sealed packaging, stored in a dry, ventilated, cool place, away from sources of fire and oxidants.

Avoid outdoor storage to prevent rainwater from seeping in and causing clumping.

Shelf life: If stored properly in the original packaging without opening, it can be preserved for 2 years.

Conventional: 25kg/woven bag (lined with polyethylene film, leak proof), 500kg/ton bag.

Domestic: default car transportation (3-7 days delivery), large quantities can be transported by railway;

International: Supports sea freight (FOB/CIF terms) and provides customs declaration documents (such as MSDS, packing list).

Packaging Specifications

To guarantee the quality of our anhydrous sodium sulfate and meet your operational needs, we provide two robust packaging solutions:

Standard 50 kg Bags: Ideal for manageable handling and smaller batch usage. Each bag is constructed from durable, multi-layer paper with an integrated moisture-proof plastic liner to prevent caking. Bags are securely stacked on pallets and wrapped for safe shipping and storage.

Bulk 1000 kg FIBCs (Jumbo Bags): Designed for high-volume users to improve efficiency and reduce packaging waste. Our Flexible Intermediate Bulk Containers are built with high-strength fabric and feature a certified safety factor (5:1 or 6:1) for secure lifting and transportation. Includes a disposable polyethylene liner for maximum moisture protection.
