I talked about the use of PTFE for anti-corrosion, sealing, load-bearing, and insulation. Today, the fifth category is introduced. PTFE is used for various rods, tubes, sheets, membranes, belts, ropes, packings, and gaskets. And use graphite, molybdenum disulfide, aluminum oxide, glass fiber, carbon fiber as fillers to improve the mechanical properties of pure polytetrafluoroethylene. It can be roughly divided into the following categories: anti-corrosion; sealing; bearing; Insulation class; anti-sticking class; temperature resistance class; other medical class

5. Anti-sticking category:

1. The PTFE glass cloth covering layer on the hot roller of the sizing machine can avoid the sticking roller phenomenon formed by chemical slurry, and greatly improve the production rate and the quality of the grey cloth;

2. Microwave drying conveyor belt in the food industry—compared to conveyor belts of other materials, it does not absorb microwave energy, and non-sticky objects have the advantages of energy saving and cleaning;

3. Heat-sealable anti-sticking material in polyethylene bags;

4. Anti-stick coating-used in kitchen pans, baking molds for baking bread, frozen food storage trays, electric iron backing, copier nip rollers;

聚四氟乙烯是最好的防粘材料

前面讲了聚四氟乙烯用于防腐类，密封类，承荷类，绝缘类，今天介绍第五类，PTFE用于各种棒、管、板膜、带、绳、盘根、垫片,及用石墨、二硫化钼、三氧化二铝、玻纤、碳纤维作为填充物,来提高纯聚四氟乙烯力学性能.大致可以分为以下几大类，防腐类；密封类；承荷类；绝缘类；防粘类；耐温类；其他类医用类

五、防粘类：

1.浆纱机热辊上的聚四氟乙烯玻璃布包覆层——可免除化学浆料形成的粘辊现象，大大提高生产速率和坯布质量；

2.食品工业的微波干燥输送带——较之其他材料的输送带有不吸收微波能量，不粘物因之有节电、清洁优点；

3.聚乙烯袋装封口的热合套防粘材料；

4.防粘涂层——用于厨房用锅、烘面包的烤模、冷冻食品储存托盘、电熨斗托底、复印机夹辊；
