Using PTFE and UHMW to Solve Big Problems in Food And Dairy Industry

Polymer Seals for Food & Dairy – PTFE and UHMW

Big challenges faced in the Food and Dairy Industry

There are several major issues faced in the food and dairy industry, including:Engineer_ED_PTFE_UHMW_Food_Dairy_incdustry

  • Temperature conditions that range from extremely high to cryogenic
  • Contamination
  • Exposure to harsh chemicals
  • Excessive moisture
  • Corrosion
  • Continuous sanitation regimens
  • Regulations
  • Expensive shutdowns

In these industries, simple thinks like lubrication of seals and bearings become major issues because of potential contamination.  Potential contaminants in the food and dairy industry are varied, ranging from lubricants, antimicrobial barrier fluids, insects, splinters of plastic or metal, to coolants. Even contamination at the microbial level can lead to very expensive recalls.
