Polyurethane sealing gasket, rubber O-ring, Chinese supplier

Polyurethane sealing rings are one of the preferred sealing materials under high-pressure, wear-resistant, and oil-resistant conditions, and they play a dominant role in hydraulic systems. The key to their successful application lies in "taking advantage of strengths and avoiding weaknesses" - fully leveraging their outstanding advantages in terms of wear resistance and pressure resistance, while avoiding their weaknesses in high-temperature and humid environments through proper selection (especially in terms of hydrolysis-resistant formulations).
