Description:
White crystal, easily absorbing
moisture and be slaked in the air, easily soluble in water and alcohol. If
heated above 200＜C, it will be suddenly decomposed with hydrogen phosphine
released. Moreover, it is a good strong reducer. It can explode when
contact with
oxidizing agent .

Uses:
It is mainly used as the reductant
electroless nickel-plating. By using it, a dense and uniform nickel-phosphorus
film can be obtained for both large equipment and tiny components, articles with
complicated external shape of convex/concave lines or internal wall of deep
hollows, the surface of nonmetallics such as plastic, ceramics, glass, quartz
and etc.. In addition, the film posses a good surface hardness and abrasion
resistance. The product can be widely used in electronics, aviation, mechanism,
and petroleum field. It is also used as interface activator and thermostablizer
for synthetic resins and additive for foods.
Packing: 25kg kraft paper bags inner coated with PE film, inner lined with PP bags.
