Sodium hydrosulfite is a very effective reducing
agent. Our sodium hydrosulfite comes in solid white crystalline
Designed for flexible volume usage, solid sodium hydrosulfite can
be transported easily and stored for an extended period of time.
It has wide applications in various industries, including textile,
pulp and paper, Kaolin clay, and water treatment.
Flexible yet safe
Sodium hydrosulfite is highly stable if stored and kept carefully.
Our solid hydrosulfite has a shelf life of over 12 months. We provide
a wide variety of packaging, 50KG drums, 100KG, 200KG to 1,800MT
Intermediate Bulk Containers (IBC). We give you the option to choose
the most appropriate packaging to minimize package handling and
air exposure. All our solid hydrosulfite comes with inner liners
as an extra precaution against moisture and water.
Patented Innovative bulk packaging
Designed for volume users, our UN-approved IBC pioneered the industry’s
first patented bulk packaging for marine transportation. Key benefits of
the IBC include
- Safety - Unique inner liners prevent moisture and water
- Convenience - Designed for easy mechanical operation
- Dust free and odorless - The liners trap all powder
and odor when the bag is emptied
- No packaging material handling - All packaging materials,
include drums and liners, can be returned to us.
Sodium hydrosulfite is commonly used in the pulp and paper industry
for bleaching brightening and de-colorization of virgin and recycled
fiber. It is also applied extensively to brighten Kaolin clay. In
textiles, the primary usage is in processing vat dyes and indigo
dyes. Other applications include water treatment, leather processing
and food bleaching (sugar, honey and gelatin).
heavy metals such as Pb (ppm)
Our solid sodium hydrosulfite is highly stable
when stored in dry closed containers. However, solid sodium hydrosulfite
is a very reactive chemical which can decompose when exposed to
air and moisture or in contact with small amount of water. Decomposition
will result in spontaneous ignition and liberation of toxic SO2.
The chemical reacts violently with oxidants and will explode or
Storage and handling
Our product must be always handled and stored
in sealed clean iron drums or bulk containers. Avoid contacts with
moisture, acids, oxidizing chemicals and combustible organic substances.
Protect it from heat, direct sunlight, sparks and naked flames.
Avoid damaging the packaging.
In the event of fire, use large quantities of
water to extinguish the product. Other extinguishing media may not
stop decomposition thoroughly. For details, please refer to the
