PolyMod® Advantage
PolyMod® Modified Low-Friction Seals
PolyMod® Modified Low-Friction Seals are engineered to deliver reliable, long‑term performance through advanced material innovation. These seals are produced using thermoset and thermoplastic rubber compounds that are chemically modified to achieve consistently low friction and enhanced wear resistance. Unlike surface coatings or internal lubricants that can diminish with use, PolyMod® technology embeds friction-reducing properties directly into the elastomer matrix through proprietary material modifications. This integrated approach ensures stable performance, extended service life, and dependable operation in demanding applications.
The PolyMod® Difference
- Low Friction Performance: Our seals minimize breakaway torque and eliminate stick-slip effects, enabling smoother motion and faster response times in dynamic systems.
- Extended Wear Resistance: Designed for long service life, these seals withstand high pressure, extreme temperatures, and chemical exposure without compromising performance.
- Energy Efficiency: By lowering power consumption and heat generation, PolyMod® seals allow smaller actuators, solenoids, and motors to achieve the same output, improving overall system efficiency.
- No Gland Modifications: PolyMod® seals can directly replace conventional seals in existing equipment.
- Custom Solutions: Available in a wide range of elastomer compounds such as nitrile, FKM, EPDM, and more - PolyMod® seals can be tailored to meet specific operating conditions.
Technical Advantages
- Operating Speeds: Up to 3 m/s (9.8 ft/s) without stick-slip issues.
- Temperature Range: From -54°C to +260°C (-65°F to +500°F) depending on elastomer compound.
