If you're trying to invent a highly flexible, chemically resistant, heat-resistant, non-stick and electrostatically resistant material that has not yet been finished, then you'll want to find a PTFE sheet that is almost as good as the material in these areas.

Polytetrafluoroethylene has a melting point of about 327 ° C. Polytetrafluoroethylene is almost completely chemically inert, highly insoluble in most solvents or chemicals, and has sufficient thermal stability to be used between -200 ° C and 260 ° C Will not degrade. Other useful PTFE properties are high flexural strength even at low temperatures, high resistance and dielectric strength, water resistance and low coefficient of friction. The density of PTFE is also very high, reaching 2200 kg / m3.

Pure PTFE or pure PTFE may deform under load, but using a filler can help solve this problem, but be aware that not all filled PTFE is suitable for use in foodstuffs.

In PTFE filler can increase its strength, improve wear resistance, increase conductivity and so on. However, the addition of fillers can also reduce some of the beneficial PTFE properties, such as the chemical resistance that will be limited by the filler.

The biggest advantage of Teflon is its versatility, and the range of applications of this material in many products and in different industries is staggering. The use of PTFE sheet has enormous advantages in manufacturing and engineering, not only in the manufacture of tubes or liners for handling or storing corrosive chemicals, but also in the application of parts such as bearings or screws to extend the part itself And the life of the machine part. Due to PTFE's ability to repel water and oil, the PTFE-coated screw will be corrosion-resistant and lubricated by the material to successfully drive onto any fixed surface, reducing friction and reducing the risk of screws and surfaces As well as a more permanent, safer surface.

Because polytetrafluoroethylene is non-toxic, polymer fumes are hot and approved by the Food and Drug Administration and are food safe, there are only minor contraindications to humans. In many different areas have great benefits.
