Performance and Applications of NP-4

  1. Solubility & Properties:
    • NP-4 is soluble in oils and other organic solvents, exhibiting excellent emulsifying properties.
  2. Applications:
    • As a lipophilic emulsifier, used for preparing W/O (water-in-oil) type emulsions.
    • Serves as a reaction medium in certain organic synthesis reactions, shortening reaction time and improving conversion rate. For example, in polyvinyl chloride (PVC) polymerization, NP-4 acts as a massing agent, ensuring uniform 成型颗粒 (molding particles) and preventing reaction sticking to the reactor.
    • Can also be used as a dry cleaning agent.

Packaging and Storage of NP-4

  • Packaging:
    • 200kg iron drums or 50kg plastic drums for liquid form.
    • 20kg woven bags for solid slices after molding.
  • Storage and Transportation:
    • Non-flammable; stored and transported as general chemicals.
    • Keep in a dry, ventilated place.
  • Shelf Life: 2 years.
