DuPont is a proud member of NIBA-The Belting Association

As a member of NIBA-The Belting Association, DuPont collaborates with conveyor belt and component manufacturers, distributors and customers to address the needs of the belting industry.

DuPont™ Kevlar® fiber helps enable conveyor belt manufacturers to offer equipment to mining companies that doesn’t just do its job, but changes the way the industry performs. For more information on how DuPont™ Kevlar® conveyor belts offers better throughput and less maintenance for companies like Codelco, please download our our case study here.

The toughest job on earth requires the toughest fiber on earth.

Each day, the mining industry extracts tons of ores and transports these valuable and often heavy materials to process sites using conveyor belts. The demanding conditions of the mining environment, coupled with the weight and abrasiveness of many of the materials being transported, take a toll on these conveyor belts resulting in costly maintenance and downtime.   

Operational continuity is critical to the productivity of mine operations. Today different technologies and products are available to the mining industry to help meet their needs.  DuPont has been working with other companies to develop products that help improve performance, cost-effectiveness and design flexibility.

At 10 miles deep or 20 miles across, nerves of steel are good but threads of Kevlar® are better. To learn more about how conveyor belts made with DuPont™ Kevlar® can help address your extreme mining conditions, download the latest brochure here.

Replacing conventional polyester/nylon (EP) and steel cord in carcasses with straight warp fabrics of Kevlar® fiber helps enable conveyor belts capable of delivering:

  • Increased lifetime
  • Reduced rolling resistance & energy consumption
  • Reduced number of splices
  • Reduced splice time and cost
  • Conveyor system design flexibility
  • Increased transportation capacity (better U-shape)
  • Low creep during lifetime
  • Normal operation in extreme environmental conditions
