Polyurethane is another popular material used in Vacuum Suction Cups, known for its abrasion resistance and durability. This makes polyurethane suction cups suitable for rougher surfaces or applications where wear and tear are a concern. No matter the material, each Vacuum Suction Cup is engineered to create a strong and stable vacuum seal by molding precisely to the surface it grips. https://www.shijingtools.com/product/handling-tools-suction-cup/
