Heat Resistant Belt

Product Overview

Heat destroys conveyor belt covers in two ways: the rubber hardens and cracks, and the adhesion between plies breaks down. A heat resistant belt addresses both, using a cover compound formulated for the actual material temperature and a carcass bonding system that survives it.

The right grade depends on the real temperature profile, not the peak figure on a datasheet. We ask for material temperature at the loading point, belt speed, and whether the load is continuous or intermittent, then recommend the class that will not over-harden in service.

Key Advantages

• Cover classes T1 to T5 to ISO 4195-2
• Special compounds for continuous duty up to 220 °C
• Resists hardening, cracking and cover-to-ply separation
• EP, NN or steel cord carcass depending on length and tension
• Also available oil resistant and fire resistant
• Test certificates issued per batch
