PETG, polypropylene, polycarbonate, uPVC, polyethene, and flexible PVC are just a few polymers available for plastic welding rods. They’re frequently used with extrusion welders or hot air plastic welding guns to thermally join two parts of the same thermoplastic.
We provide a variety of profiles, sizes, and colours at Petron Thermoplast to meet various needs. Petron Thermoplast offers an online store with a range of our most popular plastic welding rods.
