Property and Uses

PASP is a water-soluble polymer and a new type of green water treatment agent characterized by being phosphorus-free, non-toxic, non-pollutant, and fully biodegradable;
It has extremely strong chelating ability for ions, offering both corrosion inhibition and scale inhibition. It also provides excellent scale inhibition for salts such as calcium carbonate, while also dispersing and effectively preventing corrosion of metal equipment.
It can replace phosphorus-containing water treatment agents to avoid eutrophication and secondary pollution discharge.

Technical index

Scope of application

1. As a scale inhibitor and corrosion inhibitor, it is widely used in industrial circulating water, boiler water, reverse osmosis water, oilfield water, and other water treatment fields. It performs excellently in systems with high hardness, high alkalinity, high pH, and high concentration ratios, with scale resistance superior to commonly used phosphorus-containing scale inhibitors. PASP combined with PBTCA has an enhanced effect.
2. Due to its green and environmentally friendly nature, it can be used as a new type of daily chemical additive and various non-toxic, pollution-free specialized fine chemicals
3. In agriculture, it can be used as a nutrient absorption enhancer to promote the production of vegetables, fruits, flowers, and other crops. When used together with pesticides, it can improve efficacy

Packaging and storage
