Polyaspartic Acid
Category : Food and Feed additives
CAS NO : 25608-40-6 EC NO : MF : (C4H7NO4)x MW : 133.102 Specification : 40% or 90% Packing : 25kg Bag,1000kg Bag Product description : 
Product Name Poly-L-aspartic acid 99% CAS No. 25608-40-6 Purity 99% Appearance Powder/Liquid Molecular Formula C4H7NO4 EINECS No. /
PASP is a water soluble polymer, has good scale inhibition on calcium carbonate, calcium sulfate, barium sulfate, calcium phosphate, etc. Its scale inhibition rate for calcium carbonate is 100%. Moreover, PASP has dispersion and corrosion inhibition properties to metal equipment.
PASP is an alternative of phosphor-containing Water Treatment Chemicals, avoiding water system eutrophication and second pollution.
