Polyurethane
Polyurethane is a high-performance material widely used for dynamic sealing applications due to its excellent wear resistance, high load-bearing capacity, and superior resistance to abrasion. It offers an ideal balance of flexibility and strength, making it suitable for hydraulic and pneumatic systems operating under demanding conditions.
