The DuraFlow® Mesh Belts (27 & 28) are essential to a wide range of drying and curing applications throughout the world. In fact, their superior performance has resulted in AFC becoming the largest supplier of PTFE (Fluon®) coated mesh belts to the US screen print industry. DuraFlow® Mesh Belts are manufactured from proprietary woven substrates that have been heavily coated with PTFE (Fluon®). The resulting products are significantly stronger, more wear resistant, and have better airflow for faster curing and drying. AFC’s UV Resistant Mesh Fabrics (28 Series) have all the benefits of the 27 Series Mesh Fabrics, but with the added benefit of UV protection. AFC’s DuraFlow® Mesh Fabrics are unsurpassed in their surface, strength, and airflow characteristics and thus provide the ultimate performance for textile and screen print drying and finishing.

DuraFlow® PTFE Coated Belt Characteristics

DuraFlow® 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%). DuraFlow® Belts have received USDA approval for food processing and handling, and are FDA compliant (21 CFR177.1550). In addition, the DuraFlow® 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).
