Description
Premium (21 series)
| The DuraFab® Premium Series is specially engineered to meet the most demanding belting applications. Its extremely smooth, non-stick surface provides the best release, highest dielectric strength, and greatest chemical resistance of any AFC PTFE coated fabric line. These fabrics are manufactured from woven fiberglass substrates, have the highest PTFE (Fluon®)content, and leave little-to-no fabric impressions. DuraFab® Premium Fabrics are excellent for use in the most challenging applications, such as the processing of sticky or gummy materials, or certain process applications requiring an extremely smooth surface. | ||||||||||||||||||||||||||||||||||||||||||||||||||

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). | ||||||||||||||||||||||||||||||||||||||||||||||||||
