This is a video that we made a couple of winters ago, when we first started thermoforming poly fenders. It does a great job of displaying just how tough the high molecular weight polyethylene really is in below-freezing environments. The fender that gets demolished is injection molded. For some reason they claim that the injection molded is stronger.. we’re still scratching our heads, trying to figure that one out.
We will be putting together a new cold weather test this winter with some more entertaining fender abuse – stay tuned!
