1. Sealing & dust proofing: Dense fibers block dust and help prevent oil leakage, making it ideal for bearing and shaft-end sealing.
2. Oil absorption & self-lubrication: Natural wool absorbs and retains oil to reduce friction and help prevent dry wear, extending the service life of shafts and seals.
3. High elasticity & cushioning: Compression resilience ≥ 60% supports vibration and noise reduction and adapts well to uneven contact surfaces.
4. Wear & temperature resistance: Resists mineral oil and grease. Operating temperature: -40°C ~ +110°C.
5. Easy processing & customization: Available in rings, gaskets, strips, and special shapes. Size, density, and thickness can be customized.
6. Cost-effective & eco-friendly: Lower cost than rubber and PTFE. Wool is biodegradable and dust-free.
