Polypropylene is used on some ATV fenders, dirt bike fenders and gas tanks. Because Polypropylene is very stable (meaning few things will react with it), it is almost impossible to get quality repairs using adhesives, and also why it is used to contain chemicals (gasoline, pesticides, etc.) that would react with other plastics. Welding is the best repair method for polypropylene. The black color of this rod will match many black polypropylene applications, like bumper covers, where you need a more invisible repair. This package contains 1 lb. (0.45 kg) of BLACK polypropylene plastic welding rod. Each rod is 12 inches (30 cm) long by 3/16th inch (4.7 mm) in diameter. Approximately 115 rods in 1 lb. (0.45 kg).
