Polyvance's High Density Polyethylene (HDPE) plastic welding rod is made in the USA. We offer many different colors to better match the plastic you are working on. We also have several welding rod profiles to get stronger welds. Not only that, but Polyvance has our plastic welding rods packaged on many convenient sized packages. So, whether you are a do-it-yourselfer or a heavy user of plastic welding rod, you won't have to worry about having to buy more than you need.
High Density Polyethylene (HDPE) is used in many different applications in both automotive and non-automotive pieces. It has a waxy feel, like low density polyethylene, but is stiffer and less flexible. You can find HDPE in fender liners, windshield washer bottles, and overflow tanks in automotive applications. In non-automotive applications, HDPE is used for ATV fenders, gas tanks, kayaks, canoes, playground equipment, and more.
- Works with airless, hot-air, and nitrogen plastic welders.

This rod works great when used with plastic it was intended for.

I never knew you could solder plastic. I have a wheel barrel that’s made out of plastic, which had a crack in it. It was holding up, but I didn’t want the crack to increase. I use this plastic rod and a soldering iron and solder the crack. It sealed it up great and have used the wheelbarrow for hauling logs and it still holds.

Welding rod was easy to use with my plastic welder in repairing my plastic tub on my wheelbarrow. Would buy again.

Had to repair a butchered plastic fuel tank outlet on an ‘88 Porsche 944. I don’t know what happened to it or what part of what was there was someone’s idea of a repair. Either way, it leaked gasoline and was a disaster waiting to happen. With these and a Harbor Freight hot air welder, I recreated a suitable sealing surface and mitigated the leak. So far so good!

If you need a really clean joint, this probably isn't your product, but it does seem to make the joint stronger. I ended up having to clean it up with a Dremel tool. So if strength is your priority, this is good stuff. If you need pretty, or a sharp corner, take another route perhaps?

I guess it's fine for certain jobs, but specifically for welding with Dagger whitewater kayaks it wasn't the best consistentcy when heated. Ended up cuttung a bit of the back of the cockpit instead

Actually had to use this to repair plastics on my quad, works will with Harbor Freight plastic welding kit and a heat gun. I actually had to fill in some big support holes with stainless screen and his stuff, works well on high stress areas. Wish I discovered plastic welding 30 years ago.
