Product Description |
|
 The DuraFab® Industrial Series is the workhorse of AFC’s product line. It is the most extensive line of fabrics, serving a broad range of industrial and general-purpose applications. These fabrics are manufactured from woven fiberglass substrates, possess an optimal PTFE (Fluon®) content, and leave a minimal fabric impression. As AFC’s most popular and versatile fabric series, DuraFab® Industrial Fabrics provide the highest value to customers by offering an excellent balance between heat transfer, release, and flexibility.

PTFE Coated Fabric Characteristics |
|
DuraFab® Fabrics 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, durability, excellent tensile strength and extremely low elongation (<1%). DuraFab® Fabrics have received USDA approval for food processing and handling, and are FDA compliant (21 CFR177.1550). In addition, the DuraFab® fabrics 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).

Please note: Additional thickness and styles available upon special order and lead times may vary for different styles and widths.
*Disclaimer: All figures provided in the above table are based upon ASTM D 4969-97, the Standard Specification for Polytetrafluoroethylene (PTFE) Coated Glass Fabric. The above tensile values are based upon the ASTM D828 test method and are not actual values of AFC’s materials. The above tensile values are 80% of the figures provided in Table 6 of specification D579. AFC states that its actual tensile will be greater than the above material specification and that actual tensile values will be provided upon request. Edge Tear values are based upon ASTM D1424 (Elmendorf Tearing Test) and are average values that can vary.
