Known Appli­ca­tion

  1. 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.
  2. Agri­cul­tur­al appli­ca­tions
    PSI can be fur­ther con­vert­ed into polyas­par­tic acid and used as a soil con­di­tion­er, slow-release fer­til­iz­er car­ri­er to improve nutri­ent release.
  3. Biodegrad­able mate­r­i­al raw mate­ri­als
    Its deriv­a­tives such as PASP can be used for bio­ma­te­r­i­al devel­op­ment, such as med­ical slow-release mate­ri­als and bio­com­pat­i­ble carriers.
  4. Chem­i­cal inter­me­di­ates
    PSI itself can also be used for fur­ther chem­i­cal mod­i­fi­ca­tion to syn­the­size oth­er func­tion­al poly­mers or resins.
