1. Description
PU (Polyurethane): A versatile polymer material known for excellent abrasion resistance, high tear strength, and good flexibility over a moderate temperature range (-20°C to 80°C, occasionally up to 100°C). It exhibits strong resistance to oils, greases, and many hydraulic fluids but may be less effective against aromatic solvents and strong acids. PU is widely used in dynamic sealing applications like hydraulic cylinders and pneumatic systems due to its durability and low friction properties.
