Application:
MSHA Flame Retardant Conveyor Belt is used in underground mining, conveyor belt for general purpose,conveying flammable materials, heat resistant conveyor belt, such as mining sinter, cinder, coke, etc.
Characteristics:
1. High tensile strength with heavy load
2. Flame retardant and anti-static rubber surface
3. Special treatment for fabric, greatly improved the anti-inflammability and adhesion
4. Anti-impact, abrasion and corrosion resistant
5. MSHA Approval
Standards: MSHA (Mine Safety and Health Administration)
