Properties:
PASP is a kind of biopolymer materials, of which molecules contains abundant amido bond, carboxyl and other active groups. Amido peptide bond has biological activity and high chemical stability, hard to decompose at high temperature; carboxyl group can be complex with many metal ions in water, which make PASP have high chemical activity in aqueous solution; in each structural unit of PASP, the oxygen and nitrogen atoms can easily form hydrogen bonds with water molecules, it has good hydrophilicity and water solubility. The special molecular structure of it ensures that it has good dispersing ability, corrosion inhibiting properties, excellent biodegradability and environmental friendly characteristics.

Usage:
According to different molecular weights of PASP, it can be used in water treatment, agriculture and forestry, petroleum exploitation, detergents and other fields.
I. Petroleum exploitation
-
PASP can form chelation with calcium, magnesium, copper, iron and other metal ions to attach to the metal surface of the container to prevent metal corrosion. It is an excellent corrosion inhibitor, especially for preventing oil pipeline corrosion caused by carbon dioxide;
-
PASP with molecular weight around 10000 can reduce fluid viscosity. In bentonite mud, when the dosage of PASP is 0.4%, the viscosity reduction rate can be over 70%;
-
It has good resistance to salt and calcium;
IV. Detergents
-
PASP has characteristics of anionic surfactant and good chelation, dispersion properties. It can soften water, dispersing, anti-fouling, and prevent re-contamination of the greasy dirty off the clothes during the washing process;
-
It can be adsorbed on the surface of dinnerware, prevent mouldy, resulting in better cleaning effect. It is an important component of dishwashing detergent for cleaning of hard surfaces;
V. Other Applications
PASPis called “third-generation polyurea”, it can be used to produce protective coatings of high weather resistance, high resistance to chemical corrosion, fast-curing paint, and applied directly to fast curing coatings on the metal substrate and industrial flooring, etc., ; it can be used in the tanning process as tanning agents, produces biodegradable leather; pharmaceutical carrier material made from it has been widely used in family planning, anti-tumor drugs making etc.

protective measures:
Here are some general protective measures that can be applied:
- Personal Protective Equipment (PPE): Wear appropriate PPE such as gloves, safety goggles, and protective clothing when handling PASP to minimize skin and eye contact.
- Ventilation: Ensure good ventilation in the working area to prevent the build-up of vapors or fumes.
- Handling and Storage: Follow proper handling and storage procedures as specified by the manufacturer. Store PASP in a cool, dry, and well-ventilated area away from incompatible substances.
- Spill Response: In case of a spill, contain and clean it up promptly according to appropriate spill response procedures. Use absorbent materials and dispose of them properly.
- Disposal: Dispose of PASP waste in accordance with local regulations and guidelines. Do not dispose of it in regular trash or pour it down the drain.
It’s important to consult the Safety Data Sheet (SDS) provided by the manufacturer for specific information on safe handling, storage, and disposal of PASP.
