Cross-Linked Polyethylene Repair Video Released

Polyvance has just released a new video explaining how to repair cross-linked polyethylene. The video demonstrates a repair of a puncture, a crack, and a hole in an XLPE fuel tank. The repair is made by using Polyvance's KCWPRO airless plastic welder and low density polyethylene welding rod.

Cross-linked polyethylene is not very common, but it is sometimes used for fuel tanks, kayaks, canoes, and older ATV parts. It is an extremely durable plastic, and unfortunately, it is not easily repaired. Cross-linked polyethylene is a thermoset plastic, which means it is not meltable. Because cross-linked polyethylene is not meltable, a nitrogen plastic welder or airless plastic welder cannot be used to create a fusion weld. Instead, an airless plastic welder and thermoplastic polyethylene welding rod will be used to make a bonded repair.

The thermoplastic polyethylene welding rod will be used as a hot melt adhesive. This process is similar to how we apply FiberFlex welding rod.

Here's the video:
