Resilon D-Ring Seals
Parker’s proprietary PPDI-based Resilon family of polyurethane materials delivers the best over- all sealing performance of all commercially available TPUs. Its superior resilience/rebound characteristics and thermal stability distinguish it from other MDI and TODI formulations – evidenced by successful, reliable sealing in applications where there are likely to be severe shock loads and momentary pressure spikes. Resilon 4301 polyurethane can be used at temperatures where normal polyurethanes break down because its unique formulation makes it resistant to hydrolytic deterioration.
Product Highlights:
- Will not crack when exposed to water-based fluids
- PPDI polymer backbone
- Improved strength and wear-resistance extends seal life

Product Features:
- Water resistant formulation
- Will not crack when exposed to water-based fluids
- PPDI polymer backbone
- 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
Comparison of Typical MDI-based TPU vs. Resilon® 4301 Polyurethane
From left, aqua-colored Resilon 4301 polyurethane seals and competitor’s yellow conventional MDI-based urethane seals as manufactured (Frame 1); after 1493 hours of exposure to 212°F water (Frame 2); and after 1493 hours of exposure to steam (Frame 3).
Resilon 4301 polyurethane vs. conventional urethanes High-performance polyurethanes may meet long life and/or high pressure operating criteria in oil-based fluids; however, more applications are using water based fluids for environmental or safety concerns. At room temperature, water-based fluids cause little problem, but as the temperature rises even the toughest long wearing materials start to suffer from hydrolysis or breakdown of the molecules. PPDI- based Resilon 4301 polyurethane can be used at temperatures where normal polyurethanes break down because its unique formulation makes it resistant to hydrolytic deterioration. Resilon 4301 maintains excellent physical properties at operating temperatures as high as 212°F.
