Through material analysis, Smithers can conduct adhesion and abrasion resistance testing. By benchmarking materials and products, we can create an objective, reproducible, data-based foundation to compare rubber conveyor belt constructions, compositions, performance properties, reinforcements’ characteristics and other properties.

Smithers US and European laboratories are also equipped to conduct a variety of chemical analyses procedures used for product development inclusing:

  • Compound deformulation / formulation
  • Service life prediction
  • Quality assurance
  • Conveyor belt failure analysis
  • Forensic investigation

Smithers can test to a range of industry standards for conveyor belts as noted below. For conveyor belts used in food processing and production, we can also support you with relevant migration testing for food contact materials.
