FiberFlex is Polyvance's "Universal" rod. It is not a true fusion weld, though. Instead, the FiberFlex is a hot-melt adhesive that is applied with an airless plastic welder. So, it is similar to a brazing process. It sticks great to polypropylene and TPO. This package contains 30 ft. (9.14 m) of FiberFlex rod. Each rod is 12 inches (30 cm) long and is 3/8th inch (4.76 mm) wide and 1/16th inch (1.6 mm) thick.
