Description

The DuraFab® Mechanical Series features a more textured surface, and provides the most cost effective solution for mechanical applications. These fabrics are manufactured from woven fiberglass substrates and have a moderate PTFE content. These fabrics are lightweight and possess good release characteristics for less demanding or less critical applications. The non-porous Mechanical Fabrics are ideal for applications where a mechanical impression must be transferred to a seal or a surface texture is required.

DuraFab® 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 (21CFR177.1550). In addition, the DuraFab® fabrics can operate in temperatures from -400ºF(-240ºC) under static conditions and -100ºF (-73º C) under dynamic conditions up to 550ºF (288ºC).
