A strong polytetrafluoroethylene (PTFE) based fluoropolymer resin impregnated open mesh fiberglass fabric. The mesh allows air-flow to increase the rate of drying. Applications requiring superior air and heat transfer can benefit from the use of PRECISIONMESH™ Open Mesh Belts. Air flows readily through the 1/16 or 1/4" open weave of PRECISIONMESH™'s woven fiberglass substrate, making it ideal for use in heat tunnels and process freezing applications.
