- The Polyvance R10-04-03-BK FiberFlex Plastic Welding Rod may also be referred to as FiberFlex R10 ribbon rod, Polyvance flat welding rod 3/8 x 1/16, R10-04-03-BK black rod, universal plastic repair rod, and FiberFlex 30 ft ribbon rod.
Polyvance’s FiberFlex line is engineered as a universal repair rod that adheres to many plastic substrates with minimal prep. It is applied with an airless plastic welder and behaves like a brazing-style bond rather than a true fusion weld.
Q: Is this a true fusion weld rod?
A: No. FiberFlex acts as a hot-melt adhesive applied with heat; it bonds structurally but does not fully fuse into the substrate.
Q: What plastics work best with it?
A: It is compatible with a broad range, especially polypropylene and TPO surfaces where adhesion is often problematic.
Q: What size segments does it come in?
A: The rod is supplied as 30 ft total, segmented into 12 in lengths for easier placement over cracks or edges.
