SUMMARY

The discussion focuses on effective methods to dissolve PVC thermoplastic from electrical wires. Heating the wires to 80-90 degrees Celsius allows for the peeling off of the thermoplastic, leveraging its melting point. Acetone is identified as a suitable solvent for dissolving PVC due to its ability to disrupt the strong intermolecular Van der Waals forces present in the polymer. Participants confirm that acetone is readily available and effective for this purpose.

PREREQUISITES
  • Understanding of PVC thermoplastic properties
  • Knowledge of safe handling practices for acetone
  • Basic thermodynamics related to melting points
  • Familiarity with polymer chemistry concepts
NEXT STEPS
  • Research the safety protocols for using acetone in chemical applications
  • Learn about the thermal properties of PVC and its melting behavior
  • Explore alternative solvents for dissolving various plastics
  • Investigate the environmental impact of using acetone and other solvents
USEFUL FOR

This discussion is beneficial for electrical engineers, DIY enthusiasts, and anyone involved in the repair or modification of electrical wiring that requires the removal of PVC thermoplastic insulation.

How would i dissolve the pvc thermoplastic on electrical wires? (with chemicals that are attainable easily from stores)
 
Chemistry news on Phys.org
Do you simply want to remove the thermoplastic from the wires? If so, you could heat the wires to 80-90 degrees celsius, near the melting temperature, and peel it off, I suppose.

The type of PVC you talk about is likely an addition polymer (as opposed to a radical polymer), which probably doesn't dissolve easily, due to the high molecular weight and strong intermolecular Van der Waals forces.
 
Acetone dissolves PVC.

I was just going to suggest this. Acetone messes up just about any plastic.
