V&S's Low Price Magnesium Chloride Hexahydrate is a widely used and important industrial-grade chemical raw material. The product is in the form of flaky crystals, typically white or off-white in appearance, and may have a slightly yellowish tint when containing small amounts of impurities.
It has a distinctly bitter taste, is readily soluble in water, and undergoes slight hydrolysis during dissolution, resulting in a weakly acidic aqueous solution. Due to its strong hygroscopicity, it is prone to deliquescence in humid environments; therefore, it requires careful moisture protection during storage and transportation.
The product has a melting point of 116–118℃, a relative density of approximately 1.56, and stable physical properties, making it suitable for various industrial applications. It is one of the basic chemical materials that many industry customers have long relied upon.

V&S Quality Magnesium Chloride Hexahydrate, with dual specifications and stable performance, is widely used in multiple industries, covering diverse application scenarios:
1 Metallurgical Industry
Used as a binder for refractories and furnace arms, and as a raw material for No.2 flux and magnesium smelting, improving the stability and performance of metallurgical products.
2 Chemical Industry
Mainly used to produce various magnesium salts, such as magnesium oxide, magnesium hydroxide, magnesium carbonate; also used as firecracker fixative and antifreeze, with broad application prospects in fine chemical fields.
3 Building Materials Industry
Mixed with magnesia to make magnesia cement, which is hard and corrosion-resistant. It can be processed into marble, magnesia tiles, floors, ceilings, decorative boards, fireproof boards, greenhouse brackets, partition boards, magnesia manhole covers, bathtubs, door and window frames, movable houses, etc.
4 Machinery Industry
Used to make mechanical packing boxes, triangular cushion edges and furniture in daily production and life, serving as an excellent "soil replacement" material with good toughness and durability.
5 Food Industry
The brine made from high-purity White Magnesium Chloride produces tenderer and more delicious tofu than that made from stone; it can also be used as an additive in some foods, complying with food safety standards.
6 Transportation Industry
Used as road deicing and snow melting agent, with faster deicing speed and lower corrosiveness to vehicles compared with sodium chloride, suitable for roads, expressways, parking lots and ports in cold regions.
7 Agriculture Industry
Used as magnesium fertilizer, potassium-magnesium fertilizer to supplement essential nutrients for crops; also used as cotton defoliant, improving cotton picking efficiency and quality.
