Teflon®/Glass Belting. Our PTFE-coated Fluorofab ® fabric is used to fabricate conveyor belts of up to 197″ in any length. More than 70 different weights and widths of Fluorofab ® belting are available and serve many uses – typically where a superior non-stick surface is essential and when the operating temperature range is from -100°F to +550°F.
