HBD / Thermoid® has been a leading innovator in lightweight belt technology for decades. Many improvements that have now become industry standards were pioneered in our research laboratories:
  • 100% polyester and 50%-50% polyester-cotton blends for greater strength and moisture resistance in lightweight fabrics;
  • Nitrile rubber to dramatically improve oil resistance in food belts;
  • Special adhesive treatment for synthetic carcasses that helps keep plies from separating; and
  • Multi-ply PVC belt to the food industry, among others.


  • Today, our conveyor belts can be seen in Food Handling, Agriculture, Package Handling, and Light Industrial & Automation applications around the world.

    HBD / Thermoid® specially designs fabrics and covers for conveyor service. Our textile engineers develop special weaves to handle a wide range of tensions, loads, pulley sizes and troughing angles. Our experienced research chemists develop cover compounds to cope with conditions like oil and grease, heat and cold, chemicals, acids, moisture and abrasion. Our belting colors are scientifically developed to remain easy on the eyes under all types of illumination. Plus, we offer special surfaces from extra-smooth to deeply textured to ensure your materials are conveyed properly to their destination.
