What is the dump box made of?
Materials for the Ursa Wagon are sourced from the best suppliers nationwide. The sled is composed of the highest quality High Molecular Weight Polyethylene (HMWPE) with the highest available U.V. protection (UV-8) and a temperature rating to -40 degrees F. Ursa resins meet FDA specifications and may be used as an article or component of articles intended for use in contact with food, subject to any limitations in the regulations. The resins will not be broken down by barn acids. While we had hoped to use recycled material in the molded cargo sled, our research revealed that, with the wall thickness of the cargo sled, these materials could not hold up under extreme weather or use. As a virgin resin, the Ursa sled has 40% more tensile strength than recycled plastics and its source is 100% traceable. We concluded that durability and long product life is better for the environment than having owners scrap numerous cracked dump boxes made of secondary resins.
