Ecopur Green
- Ecopur Green is a high-performance thermoplastic polyurethane (TPU) elastomer, recognized for its excellent mechanical strength, abrasion resistance, and low compression set. This material is commonly used in hydraulic and pneumatic sealing systems under the trade name "Ecopur" in green to identify its specific formulation. It offers outstanding resistance to wear, oils, and greases, making it ideal for high-pressure dynamic sealing applications. With an operating range typically from -30°C to +100°C, Ecopur Green is used in piston seals, rod seals, scrapers, and guide rings across industrial, automotive, and hydraulic systems. It is valued for its long service life and consistent performance in demanding environments.
