  There are different types of fillers used in PTFE like glass microspheres, silicate/quartz, barium sulphate, graphite or carbon, stainless steel, etc. The various benefits of PTFE with fillers are: ·         It can have a temperature resistance of 200 ℃ to 260 ℃ . ·         PTFE with fillers can provide a good media resistance apart from when used with some fluorine compounds and liquid alkali metals. ·         It can operate continuously up to 260 ℃ without causing any physiological damage. ·         It conforms to the Federal Food, Drug, and Cosmetic Act. ·         It follows the regulations for usage in food in Europe and Asia. ·         It is UV resistant and it does not age. ·         It does not embrittle. ·  ...

  Introduction: PTFE stands for Polytetrafluorethylene. The other name for this non-stick material is Teflon. It can resist huge temperature changes as it is made of low friction material. PTFE has high density and is highly flexible. It is non-toxic as it is chemically unreactive and indissoluble. All these properties make PTFE apt for a wide range of applications but as it is highly flexible heavy loads can damage it. This issue can be resolved by adding fillers to the PTFE. The fillers can increase the thermal conductivity of PTFE. There are different types of fillers out of which glass is used most of the time. Other fillers can be polyamide, graphite, carbon, bronze, stainless steel, molybdenum disulfide, etc. These fillers are chosen according to the application. Types of Fillers and their Advantages:          PTFE with Glass Fillers : Glass is the most widely used filler in PTFE. Glass fillers enhance the strength and durability of PTFE. Th...
