Tetrafluoroethylene plate is known as the king of plastics in the field of plastics, and its performance is unrealized by ordinary plastics, so it is generally used in places with harsh environments, such as acid and alkali, corrosive media and high temperature. So, what are the advantages of PTFE board?
First, it has high temperature resistance. As far as the current use of tetrafluoroethylene sheet materials is concerned, the raw material can reach 232 °C, and even the high temperature after returning to the cage can reach about 150 °C, and the use temperature is very wide.
The PTFE sheet has excellent dielectric properties, outstanding dielectric strength and arc resistance, low dielectric loss tangent, and poor corona resistance. The tetrafluoroethylene sheet has good non-water absorption, oxygen-free, UV and weather resistance. The outdoor tensile strength remained basically unchanged for three consecutive years, only the elongation decreased. Teflon films and coatings are permeable to water and gas due to their fine porosity. PTFE can actually be suitable for ambient temperatures between minus 190 degrees and 250 degrees. It can be hot or cold suddenly, or alternating hot and cold without any effect. In addition to solving chemical and petroleum production problems, tetrafluoroethylene sheets can also play a role in pharmaceuticals and other fields. There are many sealing components on the market today, as well as gasket or gasket products. In addition, PTFE is also widely used in materials with sealing requirements, and is also commonly used as Jinxining filler. The role of the PTFE sheet is very great, because the PTFE sheet has a great role, a wide variety of products, and plays a huge role in various fields and spheres of influence. PTFE can be seen everywhere in our life.
Secondly, no matter what type of chemical substance it is, no matter how corrosive it is, PTFE can basically be used. It can be said that if the PTFE sheet cannot meet the corrosion resistance requirements, no other plastic materials can be used. In addition to its excellent chemical resistance, its mechanical properties are also very outstanding, which makes it suitable for use in occasions with large swings and bends.
PTFE sheet is widely used in engineering plastics such as high temperature 260℃, low temperature -196℃, acid and alkali corrosion resistance, weather resistance and non-toxicity. PTFE can be seen in the petroleum, chemical, medical, electronic and even food industries. Whether the PTFE plate is toxic and has good wear resistance, it is a good sealing material. PTFE (Polytetrafluoroethylene, abbreviated as PTFE), generally referred to as "non-stick coating" or "easy-to-clean material". This material has the characteristics of acid and alkali resistance and resistance to various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE plate has the characteristics of high temperature resistance and extremely low friction coefficient. In addition to lubrication, the manufacturing process of PTFE plate coating has also become an ideal coating for easy cleaning of the inner layer of water pipes.
