Average molecular weight is an important property of polymers and is an indication of strength and flexibility.
After use, the waste NMP is contaminated with:
- Polymer fragments
- Monomers
- Other solvents
Name: N-Methyl-2-pyrrolidone
Formula: C5H9NO
Boiling Point: 202-206 °C
The 9600-90 is a good choice for recycling NMP waste. Key features are:
- All glass and Teflon contact surfaces.
- High efficiency distillation. Get back HPLC grade NMP
- Completely automatic. Push start and walk away.
- Safe! CE marked
