Teflon (PTFE) glass fiber fabrics operate at temperatures between - 270 C and + 270 C. Due to its properties such as resistance to all chemical substances (moisture, acid, solvent, oil, etc.), resistance to friction, non-stickiness, non-flammability, electrical insulation, flexibility, high heat conduction, its surface does not deteriorate under various resistances, is easily cleaned and reused, and leaves the material easily. preferable. It can be used in almost every sector. In the food industry, in open food cooking - cooling tunnels, biscuits, dough, etc. hot trays;
