As an accredited Propyleneimine factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Propyleneimine is packaged in a 1-liter amber glass bottle, sealed with a Teflon-lined cap, labeled with hazard and safety information. |
| Shipping | Propyleneimine must be shipped as a hazardous material in compliance with international regulations (UN 1921, Class 3, Flammable Liquids, Subsidiary risk: Toxic). It should be packed in tightly sealed, corrosion-resistant containers, clearly labeled, and kept away from heat, sparks, and incompatible substances. Proper protective measures and documentation are required during transport. |
| Storage | Propyleneimine should be stored in a tightly closed, corrosion-resistant container in a cool, dry, and well-ventilated area, away from heat, sparks, open flames, and incompatible substances such as acids and oxidizers. The storage area should be equipped with spill containment and have proper signage. Access should be restricted to trained personnel, and containers must be clearly labeled. |

Purity 99%: Propyleneimine with 99% purity is used in the synthesis of polyamines, where it ensures high molecular weight and uniform chain length distribution. Viscosity low grade: Propyleneimine of low viscosity grade is used as an epoxy resin modifier, where it enhances the flow and curing profile of the formulation. Stability temperature 25°C: Propyleneimine with a stability temperature of 25°C is used in pharmaceutical intermediate production, where it prevents degradation and ensures consistent active ingredient quality. Molecular weight 43.08 g/mol: Propyleneimine at molecular weight 43.08 g/mol is utilized in the manufacture of ion-exchange resins, where it delivers optimal cross-linking efficiency. Moisture content ≤0.1%: Propyleneimine with moisture content not exceeding 0.1% is used in the preparation of paper strength agents, where it minimizes hydrolytic side reactions. Reactivity high: Propyleneimine with high reactivity is used as a crosslinker in polyurethane foam production, where it accelerates curing and increases compressive strength. |
