What is Resilon®?
Thermoplastic polyurethanes (TPUs) have been an industry standard for dynamic sealing in hydraulic applications for the past 30+ years. Thermoplastic polyurethane materials are prepared by reacting three basic components: diols or polymeric polyols, diisocyanates, and chain extenders. Different combinations of these ingredients yield TPUs customized for specific performance requirements. Most TPUs in use today are polymerized with one of three diisocyanates, each yielding different performance characteristics.
Resilon® is Parker's proprietary polyurethane. Our PPDI-based polymer chemistry provides specific advantages over conventional polyurethanes including excellent flex resistance, superior dynamic properties, and good cut and tear resistance at the temperature limits for polyurethane materials. We have Resilon® polyurethanes that can operate at temperatures approaching 275°F (135°C) versus MDI-based compounds which are limited to around 212°F (100°C).
Our advantages include:
- Extended seal life
- Superior high-temperature resistance
- Enhanced extrusion resistance
- Leakage control

Our Resilon® Compounds
Resilon® 4300
As our cornerstone Resilon® material, 4300 provides an expanded temperature range and superior compression set resistance which results in superior strength and wear-resistance to extend the life of your equipment.
Resilon® 4301
Our Resilon® 4301 polyurethane is a water-resistant formulation that will not crack when exposed to water-based fluids. This material can also be used at temperatures where other polyurethanes break down due to hysteresis.
Resilon® 4304
Perfect for high pressure applications, our 4304 material offers the same expanded temperature range and superior wear-resistance as Resilon® 4300 while offering higher extrusion resistance.
Resilon® 4311
Our low friction Resilon® 4311 is formulated to resist internal heat generated through hysteresis, making this compound ideal for shock applications.
Resilon® 4350
With 30% more sealing force at 250 degrees Fahrenheit, our 4350 material will last longer in high temperature applications.

Proprietary Resilon® Polyurethane Raises the Bar for Seal Durability in Frac Pumps
Challenges abound for oil and gas companies during drilling and well completion operations. Drilling mud and frac fluids are some of the harshest and most destructive media to be sealed. It takes tough, rugged sealing components to last long run-time hours and continuously move high volumes of abrasive frac fluid that cause wear and tear on parts.
When the Heat is Turned Up on Your Polyurethane Seals, Consider Resilon® 4350
Have you had problems with your polyurethane seals degrading, especially when exposed to higher heat creating the need to replace your seals more often than you would like? As you probably know, seal replacement creates costly downtime that can be avoided if you have an appropriate seal for the job. Parker's Resilon® 4350 polyurethane is up for this task. Resilon® 4350 is designed for sealing at higher temperatures up to 250°F continuous and can withstand short-term excursions of up to 300°F without leakage.
