Properties:
Yellow powder with little odor,no poison. The density is 1.31-1.34 It is not stability, it can be reduced content and then become to soluble sulfur. Insoluble in CS2 and water. Store a well ventilated area Below 30C, avoiding exposure to sunlight . Do not store near products that can emit free amines and Other alkaline vapors.

Applications
It is metastable, so the temperature should be kept as low as possible during mixing. Between 100-130 significant reversion can take place to soluble sulfur. Insoluble sulfur reversion can take place if it is in direct contact with alkaline components. Due to he best dispersion, during mixing it seldom appear electrostatic charge accumulating, form agglomerates and affecting mixing effect.

Package
25Kg paper-plastic film bag, Kraft paper bag and Or jumbo bag.
