The fiberglass cords in the rubber belts has a sizing agent that assists in bonding the fibers to the rubber during the molding/vulcanizing process. Water breaks down that sizing agent resulting in fretting of the glass cords that precipitate belt failure. Saw this first hand in a wheelchair application.
The Polychain shouldn't have this problem, as the manufacturing process is completely different. The cords are completely embedded within the polyurethane body of the belt and the sizing agents are supposedly not as sensitive to moisture. N.
