Product Name:Feed Crade Zinc Sulfate Heptahydrate
Type: Zinc sulfate series
Chinese Name:饲料级七水硫酸锌系列产品
Molecular formula:ZnSO₄ 7H₂O
Molecular weight:287.56

Physical and chemical property

White or slight-yellow crystal, loose and no agglomeration, easy soluble in water and slightly dissolvable in alcohol and glycerol, insoluble in liquid ammonia and ketone, tending to lose water molecules of hydration in dry air and become white powder appearance. When the temperature is 280℃, it will become no water substance and lose all crystal water. When the temperature is above 500℃, it will decompose.

Relatively density: 1.975

Melting point: 100℃

Use

It is necessary microelement and additive for the feed in stockbreeding and fishery and it can prevent disease, urge up growth and improve nutrition quality.

Characteristic and function

It can be used as the feed additive and its cost is lower compared with zinc material and units so it can reduce the cost of feed.

As feed additive, it can enhance nutrition quality and prevent disease.

Packaging and transportation

Plastic woven bag lined with plastic film bag. Standard net weight: 25kg or as per customer’s requirement. Avoid moisture during the transportation and storage.
