Polypropylene Imine (PPI)

Polypropylene Imine (PPI) is a heterocyclic cationic polymer, also known as a dendritic polymer, produced by the polymerization of methyl aziridine under specific conditions. It contains a high density of active hydrogen and amine functional groups, enabling both chemical reactions with various functional groups and physical mechanisms such as electric neutralization, bridging adsorption, and flocculation of suspended substances.

Product Description

Polypropylene Imine is a highly reactive amine-rich polymer with both hydrophobic and hydrophilic characteristics. Its structure allows it to chemically react with multiple functional groups while also promoting electric neutralization, adsorption bridging, and flocculation of suspended particles.
The hydrophilicity of PPI can be adjusted by incorporating hydrophilic substances, making it highly selective and adaptable for different industrial applications.

Product Application Areas

  1. Water Treatment & Sewage Treatment

    • Acts as a coagulant and flocculant

    • Exhibits good separation performance due to controlled hydrophobicity

    • Hydrophilicity can be tailored to enhance selectivity

    • Particularly effective in heavy metal wastewater treatment

  2. Heavy Metal Chelation

    • Widely used as a heavy metal chelating agent

    • Efficiently removes metal ions through coordination with amine groups

    • Provides enhanced performance in industrial wastewater purification

Packaging & Storage

  • Packaging: 25 kg plastic drums or user-specified packaging

  • Storage conditions:

    • Store in a dry, cool, and tightly closed environment

  • Shelf life: 12 months from the date of production under original packaging conditions

  • Safety classification: Non-flammable and non-explosive; classified as general dangerous goods
