Paraformaldehyde with low degree of polymerization is a solid particle because it is higher than the effective component of Industrial formaldehyde. It is conducive to the application of chemical synthesis such as chemical industry and pharmacy and other industrial fields, especially in the synthesis requiring the use of anhydrous formaldehyde as raw material. It can also be used as disinfectant, bactericide, fumigant and herbicide, as well as resin and artificial ivory.
Potassium sulfate is an inorganic salt with chemical formula K₂SO₄, which is a white crystalline powder. The appearance of agricultural potassium sulfate is mostly light yellow. Potassium sulfate has small moisture absorption, is not easy to agglomerate, good physical properties and convenient application. It is a good water-soluble potassium fertilizer and the main raw material for making chlorine free nitrogen, phosphorus and potassium compound fertilizer.
