Paraformaldehyde

Paraformaldehyde / 30525-89-4 industrial grade the delivery in time Specifications 1.CAS No. 30525-89-4 2. Mainly use for making various kinds of synthetic resin and binder,etc Paraformaldehyde; The paraformaldehyde of low polymerization degree(PF ) is an important industrial chemicals at the industry. It has high purity , good water solubility, complete depolymerization, etc. characteristic. And its product is loose and the granule is even. It is also easy to store and transport. So it is the ideal substitute of industrial formaldehyde. It is widely applied in many fields, such as the chemical industry, pharmacy, agriculture chemical, coating and so on, especially in such synthetic fields which need to use the anhydrous formaldehyde as raw material.
