Polytetrafluoroethylene is a material that can be used in many fields and considered as "plastic king". Polytetrafluoroethylene (PTFE) thin film has many high-quality properties, making it widely used in many chemical, electronic, electrical, mechanical and other fields.

Here, we will first explain to everyone what polytetrafluoroethylene film is. The so-called polytetrafluoroethylene film is a type of film made of polytetrafluoroethylene. PTFE is a microporous film made by rolling, extrusion, biaxial stretching, and other methods. Based on usage,Polytetrafluoroethylene filmIt can be divided into clothing membranes, air filtration membranes, and air purification membranes. Polytetrafluoroethylene membrane has a fibrous microporous structure with a porosity of over 80%, with a1.4 billion micropores with a pore size range of 0.02 μ M-15 μ M. Due to the fact that the fabric matrix of polytetrafluoroethylene material is glass fiber, the diameter range of the fibers should be within3.30-4.05 μ Between m, its weight should be greater than 150 g/m. The coating is mainly made of polytetrafluoroethylene resin, with a content of not less than 90%. The coating quality is almost greater than 400 g/m, and the film thickness is greater than 0.5mm.

Next, let's take you through the performance of polytetrafluoroethylene film.

1.  The relative density of polytetrafluoroethylene is relatively high, making it difficult to absorb water, thus the material has toughness and elasticity. Its friction coefficient is very small and almost constant, while its wear resistance is better.

2. Among the similar materials, the thermal stability of polytetrafluoroethylene is the most prominent. When the temperature reaches at 200 degrees Celsius, the differentiation rate of polytetrafluoroethylene is relatively slow and the differentiation amount is very small, so it can be used for a long time at high temperatures.

3. Polytetrafluoroethylene (PTFE) is a good material that can withstand high and low temperatures, and has excellent dielectric properties. Above zero degrees Celsius, it is not affected by frequency, temperature, humidity, or corrosive gases. In water, its performance will not significantly decrease.

4. IPolytetrafluoroethylene film has strong chemical resistance in terms of chemical properties, hence it is calledPlastic King.
