DuraSil® Silicone Fabrics

DuraSil® Silicone Fabrics are our most conformable, flexible, and wear resistant products. They are coated on one or both sides of the fabric with silicone rubber. DuraSil® Silicone fabrics come in a variety of colors, thicknesses, and plies, and provide a higher friction surface than PTFE. Learn more here, or refer to the Belt Design Guide
