Recycled filler for conveyor belt cover compounds
A belt maker evaluated recovered carbon black in cover compounds where abrasion and tear resistance are critical.
The customer faced volatile virgin carbon black prices and wanted a locally sourced alternative for part of its cover compound, without reducing belt life.
- 01Selected compounds where carbon black loading is high
- 02Agreed acceptance criteria with the customer's quality team
- 03Supplied trial material and full documentation
- 04Supported lab mixing and a production trial
| Parameter | Result |
|---|---|
| Abrasion resistance | Met agreed criteria |
| Tear and tensile strength | Met agreed criteria |
| Cure behaviour | Met agreed criteria |
| Adhesion between cover and carcass | Met agreed criteria |
Blends of recovered and virgin carbon black met the agreed criteria for selected belt grades, giving the customer a second, local supply source.
