Key Benefits of HPU (Hydrolysis-Resistant Polyurethane)
HPU is a specialized polyurethane elastomer engineered to resist hydrolysis — the breakdown that standard polyurethane can suffer from prolonged exposure to moisture, humidity, or water immersion. Key benefits include:
- Hydrolysis Resistance: Maintains mechanical properties in humid, wet, or marine environments where standard PU degrades over time.
- High Abrasion Resistance: Withstands repeated wear and impact in dynamic applications.
- High Load-Bearing Capacity: Suited to heavy-duty rollers, wheels, and pads.
- Oil And Grease Resistant: Performs reliably in industrial and marine environments with hydrocarbon exposure.
HPU is a practical upgrade over standard polyurethane wherever moisture exposure is a long-term concern.
Common Applications of HPU (Hydrolysis-Resistant Polyurethane)
- Rollers and wheels for wet or humid environments
- Marine and offshore components
- Outdoor pads and stabilizers exposed to weather
- Seals and bushings in washdown or high-humidity settings
- General polyurethane components requiring extended service life in moisture

Q1. What Is HPU (Hydrolysis-Resistant Polyurethane) Used For?
A. HPU is used for rollers, wheels, seals, and components that need to withstand prolonged exposure to moisture, humidity, or marine conditions without degrading.
Q2. How Is HPU Different From Standard Polyurethane?
A. HPU is formulated to resist hydrolysis, the moisture-driven breakdown that can affect standard PU over time, making it a better choice for wet, humid, or marine environments.
Q3. Is HPU Suitable For Marine And Offshore Use?
A. Yes, its hydrolysis resistance makes it well suited to marine and offshore components exposed to water and humidity.
Q4. Do You Supply HPU As Custom Molded Parts?
A. Yes, we supply HPU as sheets, rods, and custom molded components to your specifications.
Q5. Do You Deliver HPU Products Across Saudi Arabia And The GCC?
A. Yes, Diode Trading EST supplies HPU products with fast delivery across the Kingdom and the wider GCC.
