DuraSil® Silicone Belting

DuraSil® Silicone Belting

DuraSil® Silicone Belting is used for applications where surface grip with excellent release is desired

Description

DuraSil® Silicone Belting

The DuraSil® Silicone Series is the most conformable, flexible, trackable, and wear resistant product line offered by AFC. This series is made from woven fiberglass substrates that have been coated on one or both sides with silicone rubber. These belts provide a higher friction surface with different release qualities than PTFE (Fluon®) coated belts. In fact, some products that may adhere to PTFE coated fabrics may not adhere to silicone coated surfaces. Available in multiple colors and with multiple plies, up to three (depending on desired tensile strength), these belts are excellent for use in applications where a surface grip with excellent release is desired such as, shrink tunnels or slightly inclined conveyors.

DuraSil® Coated Belt Characteristics

DuraSil® 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%). DuraSil® Belts have received USDA approval for food processing and handling, and are FDA compliant (21 CFR177.1550). In addition, the DuraSil® belts can operate in temperatures from -400°F (-240°C) under static conditions and -100°F (-73°C) under dynamic conditions up to 500°F (260°C).
