Resilon Polyurethane Families
Parker’s proprietary Resilon polyurethane delivers unequalled resilience, strength, and thermal stability — translating into superior sealing performance in critical engineering applications. The chemical nature of Resilon polyurethane’s backbone polymer (PPDI) produces unique dynamic properties which make it a stand- out choice for long life in hydraulic applications involving high cyclic loading.
Product Highlights:
- Performs where other polyurethanes fail
- Expanded temperature range
- Improved strength and wear-resistance extends seal life

- Expanded temperature range
- Improved strength and wear-resistance extends seal life
- Resists extrusion over a broad pressure range
- Compression set resistance helps seal maintain lip contact under rapid changes to pressure and load
- Water resistant (4301) and extrusion resistant (4304) formulations available
Delivers best overall sealing performance for heavy duty hydraulics
Three Basic Types of Sealing Grade Materials
There are three base formulations or chemical backbones used in compounding modern thermoplastic polyurethane (TPU) seal materials. They are:
- MDI (diphenylmethane diiso- cyanate)
- TODI (diphenyldiisocyanate)
- PPDI (p-phenylenediisocya- nate)
All three produce the abrasion resistance and long wear benefits that are typical of any good polyure- thane seal material. There are other physical properties though, such as heat resistance, compression set resistance, and rebound/resilience, which are major concerns in critical hydraulic applications which require effective, long-term sealing. It is in these latter performance areas that the characteristics inherent in MDI, TODI or PPDI formulations become most apparent. This unique Parker- developed PPDI-based formulation – Resilon – yields the best over-all sealing performance of all commer- cially available TPU formulations currently on the market.
Superior Heat Resistance
Rheometric examination of the dynamic behavior of MDI, TODI, and PPDI (4300) were measured under tensile mode and produced the data shown in the chart at right. The low tangent delta, tan Gvalues of Resilon PPDI across the practical application range indicate a lower ratio of energy absorbed as heat to energy returned as resilience. In addition, the higher temperature upturn of the Tan Gvalue verifies the higher softening temperature for the Resilon PPDI formulation.
Superior Resilience/Rebound
Resilon (4300) also has superior resilience/rebound characteristics compared to other available TPU materials. Quick rebound is a major advantage in applications likely to experience severe shock loads and momentary pressure spikes. In addition, Resilon’s enhanced resilience/rebound characteristics allow the sealing lips of rod or piston seal profiles to conform to the moving seal interface with greater rapidity, maintaining critical sealing lip contact.
Applications Recommended for piston seals, rod seals, wipers and O-rings for all types of light, medium and heavy- duty hydraulic cylinders, shock absorbers, off-road, industrial and construction equipment.
