The fenders have high wear resistance, corrosion resistance, impact resistance, and self-lubricating properties, and can be used to make linings for hoppers, silos, and chutes for coal, cement, lime, mineral powder, salt, and grain powder materials. Due to its excellent wear resistance, self-lubricating properties, and non adhesiveness, the above-mentioned powdered materials do not adhere to storage and transportation equipment, ensuring stable transportation.
