High Performance Systems Demand High Performance Materials Specific advantages of Parker Resilon formulations over conventional polyurethanes include excellent flex resistance, superior dynamic properties, and good cut and tear resistance at the temperature limits for polyurethane materials. Resilon Polyurethanes can operate at temperatures approaching 275°F (135°C) versus MDI-based compounds which are limited to around 212°F (100°C). Parker has customized several Resilon formulations for specific sealing challenges. |
Thermoplastic polyurethanes (TPUs) have been an industry standard for dynamic sealing in hydraulic applications for the past 30+ years. Today, design engineers have an array of commercially available polyurethane materials to choose from depending on performance expectations and application requirements. Thermoplastic polyurethanes share common characteristics making this class of material a leading choice for high pressure, dynamic sealing applications. These characteristics include:

| Material Selection When selecting from the wide range of material options that Parker offers, there are several considerations to be made:

Most recently, we have launched Resilon 4350 -- surpassing the high temperature performance of the current standard bearer, Resilon 4300. Resilon 4350 increases the normal operating window from 230°F to 250°F for continuous use in many applications while other critical performance attributes such as wear resistance, extrusion resistance, glass transition temperature, and rebound remain best in class. All of this adds up to a new solution for seal designers as they push the envelope in temperature extremes. Watch the video to see comparative test results. |

At Parker, we excel in our mission to develop high performance polyurethanes that provide our customers with increased productivity from longer seal life and extended maintenance schedules for extreme environments. Highest Performance and Quality Available 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. Learn more about PPDI, MDI and TODI base formulations here. Parker's commitment to offering the highest quality sealing material is unsurpassed in the industry. Our in-house material development and compounding capabilities give us the ability to maintain control over all variables during the manufacturing process to achieve optimal and consistent physical properties from our thermoplastic materials. |
