3R858
Rubber
Dura-Shield rubber offers a high resistance to cut, tear and abrasion. It reduces impacts and vibration. Moreover, the 3R858 has a surface that eases adhesion. It can withstand the most severe abrasive industrial applications better than other rubbers would.
Applications
- Abrasion where installation needs gluing
- Mines
- Chute linings
