Because conveyor belt covers that have a high resistance to heat often have a lower resistance to wear and tear, Dunlop have developed covers that have a combination of both heat and wear resistant qualities, resulting in a much longer operational lifespan.
High temperatures can have a seriously damaging effect on the actual conveyor belt carcass itself because heat can cause de-lamination, which is damage to the adhesion between the cover and the carcass and also between the inner plies contained within the carcass. Choosing the correct thickness of the cover is essential because the cover acts as a barrier between the heat source and the carcass.
Dunlop heat resistant conveyor belts have been developed and refined over many years so that they are more than capable of meeting the demands of even the most complex and extreme conditions, which in some cases can involve temperatures as high as 400°C.
Industries where Dunlop heat resistant conveyor belts are used with great success include the cement industry, recycling plants, the steel industry, foundries, the chemical industry and the petro-chemical industry.
Betahete – Heat and wear resistant, for materials at moderate temperatures. (Duration: 150°C. Peak 170°C)
Starhete – Increased heat resistance, for materials at controlled high temperatures. Starhete also possess very good chemical and oil resistant properties. (Duration: 180°C. Peak 220°C)
Deltahete – Superior heat resistance for heavy duty service conditions, at temperatures up to 400°C for a short period such as coke, clinker etc. (Duration: 200°C. Peak 400°C)
All our standard Multi-ply and Steel reinforced conveyor belts are available with heat resistant covers.
