Recognising Plastic welding materials

Light a small sliver of the material to be welded and observ the smell and smoke

  • For PVC: blackish smoke and acrid smell.
  • For Polyethylene (PE): no smoke, the melted material drips like candle wax and smells of wax.
  • For Polypropylene (PP): no smoke, the melted material drips like candle wax and smells of burnt oil.
  • For Polyamide (PA): no smoke, melted material pulls to form a thread and smells of burnt horn.
  • For Polycarbonate (PC): yellowish sooty smoke, sweet smell.
  • For ABS: blackish smoke, sooty flakes, sweet smell.

    Plastic welding rod can be ABS, PVC, Polypropylene, polyethylene, and many other types of thermoplastic. Plastic welding rod is available in a wide range of colours to match (or contrast) the parts being joined.
