DuraLam® Gold Fabric (25 Series)

DuraLam® Gold Fabric (25 Series)

DuraLam® Gold Fabric (25 Series) are non-stick, offer excellent release and are resistant to oils, grease and chemicals.


DuraLam® Gold Fabric (25 Series)

DuraLam® Gold Fabrics are specifically engineered to maximize application life while minimizing down time in the most demanding environments. These fabrics are manufactured from PTFE coatedwoven fiberglass substrates, utilizing AFC’s proprietary coating formulations and/or laminating process. DuraLam® Gold Fabrics are non-stick, offer excellent release and are resistant to oils, grease and chemicals. DuraLam® Gold Fabrics are available in either an extremely smooth surface for maximum release or a texturized finish for a mechanical release. The texturized surface provides a mechanical bond or seal, which is desired in many heat-sealing applications. DuraLam® Gold Fabrics are more abrasion resistant and maintain their low coefficient of friction even after prolonged service. DuraLam® Gold Fabrics are excellent for use in the most challenging applications, such as PVC window welding, food processing, baking sheets, oven liners, clam shell grill sheets, toaster sheets, IV Bag sealing, Mylar Balloon sealing, rubber extruding, flexible packaging as well as many other applications. DuraLam® Gold Fabrics have been designed to out perform and out last all competitive products.

DuraLam® Gold Fabric Characteristics

DuraLam® Gold 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, excellent tensile strength and extremely low elongation (<1%). DuraLam® Gold Fabrics have received USDA approval for food processing and handling, and are FDA compliant. In addition, the DuraLam® Gold Fabrics can operate in temperatures from -100°F to +500°F.
