Products > PTFE Belting > Industrial (20 Series)

Product Description


The DuraFab® Industrial Series is AFC’s most extensive and most popular belting series, serving the widest range of industrial applications. These belts are manufactured from woven fiberglass substrates, possess an optimal PTFE (Fluon®) content, and leave a minimal fabric impression. As the workhorse of AFC’s belting line, DuraFab® Industrial Belting provides the highest value to customers by offering an excellent balance between heat transfer, release, and flexibility.

DuraFab® PTFE Coated Belt Characteristics


DuraFab® Belts are engineered to retain the distinctive properties of PTFE; however, by adding a glass fabric to the matrix, AFC is able to obtain the added benefits of dimensional stability, excellent tensile strength and extremely low elongation (<1%). DuraFab® Belts have received USDA approval for food processing and handling, and are FDA compliant (21 CFR177.1550). In addition, the DuraFab® belts can operate in temperatures from -400°F (-240°C) under static conditions and -100°F (-73°C) under dynamic conditions up to 550°F (288°C).
