Known Application
- Water treatment agent raw materials
PSI is the precursor of polyaspartic acid (PASP), which is a non-toxic and environmentally friendly water treatment agent used as : corrosion inhibitor, scale inhibitor, dispersant ; commonly used in boiler water, cooling water and reverse osmosis systems. - Agricultural applications
PSI can be further converted into polyaspartic acid and used as a soil conditioner, slow-release fertilizer carrier to improve nutrient release. - Biodegradable material raw materials
Its derivatives such as PASP can be used for biomaterial development, such as medical slow-release materials and biocompatible carriers. - Chemical intermediates
PSI itself can also be used for further chemical modification to synthesize other functional polymers or resins.
