This set of premium non-stick, Teflon coated, fibreglass mats are made for our entire commercial range. This does, however, exclude our 28 Tray unit which will use the 50x85 cm size mats. These black coloured non-stick mats measure 40x40cm and will fit any of our normal commercial range dehydrator trays perfectly, whether using the mesh or pan trays. This set of non-stick mats are made from 100% PFOA-Free materials, but rather premium PTFE-Fiberglass coating. We use no PFOA, silicone or other dangerous chemicals! Certified as safe and approved by the FDA. These mats are heat resistant up to 260 degrees and 100% non-stick. They will keep small food from falling through the mesh and keep your stainless steel trays super clean! Made with heat-resistant advanced materials that will not burn. These mats are reusable, can be utilised on both sides, and can be used over 1000 times. Dishwasher safe and super easy to clean.
