Caprolactam grade extrusion granules
Features:
Industrial ammonium sulphate is white or light grey crystal. Relative density D=1.769,235℃ decomposition. It is hydroscopic, and apt to dissolve in water(not in alcohol or acetone),and it will become solid blocks when absorbing moisture. The aqueous solution is alkalinous. It reacts with alkali to release ammonia gas.
Application:
Used for chemical fertilizers and for production of complex fertilizers, Suitable for all kinds of soil and crops. Also can be used for food processing, textile industry, medical industry, leather processing, yeast fermentation etc.
Package:
Multi-layer bag (outer bag plastic woven bag, inner bag polyethylene film bag) or composite plastic woven bag (plastic woven cloth/film) packaging 25KG/50KG, or ton package, can be customized according to customer requirements
