Our welding rod for polypropylene with a diameter of 4mm in the colour grey is intended for the permanent welding of our PP sheets, because polypropylene cannot be bonded with conventional plastic adhesives. For high panel thicknesses, such as our PP panels in 15mm thickness, several welding seams can be made on top of each other to create a seamless transition.
Just buy as much PP welding wire as you really need.
In our online shop you are not forced to buy whole rolls of grey welding rod for polypropylene, but can order exactly the quantity you really need and even benefit from our favourable graduated prices. Simply specify the required quantity in metres and plan a small processing buffer for the run-out during welding. We recommend a buffer of about half a metre.

- The welding rod is only suitable for welding polypropylene to polypropylene
- The best welding tool for our PP welding rod is a hot air fan welder
- It is imperative to pay attention to the correct processing temperature for PP welding rod
- The PP welding rod with a diameter of 4mm thickness is also suitable for high plate thicknesses
When welding polypropylene, urgent attention should be paid to the correct temperature level as well as the heating time, because polypropylene burns very quickly. The burnt material has a negative effect on the weld seam. The temperature for welding our 4mm welding rod should be between +230°C and a maximum of +280°C in order to obtain a perfect weld.
Polypropylene cannot be bonded with conventional adhesives, which is why welding PP is common practice. However, if you do not want to or cannot weld your polypropylene plastic parts, we have developed 2-component adhesive S-Polybond PPprofi in our product range.
