Polyurethane

Seals made from polyurethane have revolutionized various industries due to their exceptional durability and versatility. These seals, formed from a synthetic compound of urethane polymers, exhibit remarkable resistance to abrasion, chemicals, and wear. With their ability to withstand a range of temperatures, polyurethane seals have become a preferred choice in applications ranging from automotive manufacturing to hydraulic and pneumatic systems. Their excellent sealing properties ensure minimal leakage, enhancing the efficiency and reliability of machinery. Furthermore, polyurethane seals offer superior flexibility, enabling them to conform to irregular surfaces and provide a tight seal. The long lifespan of these seals reduces maintenance and replacement costs, making them a cost-effective solution for countless industries. Overall, seals made from polyurethane have cemented their reputation as a reliable and durable choice, ensuring optimal performance in a wide range of applications.

Features and Benefits:

Compared to rubber materials, polyurethane has an exceptional resistance to wear and abrasion. Polyurethanes deformability is another reason why it is so commonly used in various industries. With a seal made from polyurethane being able to return to its original shape as close as possible after having a large amount of pressure and force applied. These properties mean that a lot of polyurethane seals do not have to have backup (or anti extrusion) rings while it is in applications that exert higher pressures compared to 90° (durometer) rubber O-Rings.

Polyurethane will have a good operating temperature range of -35°C up to +110°C, however different compounds of polyurethane can reach lows of -50°C and highs of +130°C. As polyurethane can be machined from tubes of the material, we are able to produce one off prototype jobs as well as very long runs of hundreds of seals without much downtime, meaning faster lead times and the customer getting their products much sooner.

Summary:

  • Excellent wear and abrasion resistance

  • Excellent deformability (easily returns to original form)

  • Brilliant under high pressure situations without the need of a back-up ring

  • Good temperature range of -35°C to +110°C (or -50°C to +130°C)

  • Efficient to turn & machine, offering small and large quantities of seals.
