The FlatClean™ is a polyurethane flat belt reinforced with Kevlar­® tensile members. This belt is designed specifically for the food processing industry and manufactured to exacting tolerances. 

FlatClean FC9 belting is made using a coextrusion process that allows for two different resin hardnesses:

  • Bottom of belt has a harder durometer urethane for greater abrasion resistance
  • Top of belt has a softer urethane for better product retention and improved wrap around smaller diameter pulleys

Product Features

  • Sealed edges and tension members prevent ingress of microbes
  • Kevlar­® tension members provide high strength, low stretch
  • Thickness controlled to exacting tolerances
  • Smooth surface allows cleaning to a microbiological level
  • Urethane material compatible with wash down environments 
  • Oil resistant

Application Characteristics

  • Reduction of in-process bacteria growth
  • Longer belt life due to minimal belt stretch
  • Reduced down time due to sanitation and belt failures
