    Product Description:

    Polyaspartic acid salts are biodegradable high molecular weight polymer, having the characteristics of no pollution, long-term effective and completely biodegradable.

    With the structure characteristics of peptide bond and active group such as carboxyl group, it has powerful functions such as chelate, dispersion, and adsorption, etc. and also compatibility well.

    Application areas: 

    Polyaspartic acid salts are widely used to prevent corrosion and scale inhibitors in the water treatment fields such as industrial cooling water recirculating, crude oil drilling etc. Besides, They can also be used as dispersing agent in cleaning products, papermaking, printing ,dyeing,shampoos and cosmetics industries.

    As the special agricultural fertilizer enhancement, polyaspartic acid salts are the raw material of the polypeptide fertilizers, water soluble fertilizer, and growing enhancement fertilizer.
