The position of PTFE sheet in the industrial field is irreplaceable. Its use can fundamentally solve the problem of easy leakage in high-temperature and highly corrosive environments. In addition to being used as a sealing material, it can also be used as an electrical insulation material, a wear-resistant platform, etc. , at least in the sealing industry, we don't have to worry about the leakage of the matching products.

It can be said that the emergence of PTFE sheet has achieved a major breakthrough in the field of sealing, and because of its existence, it has brought good news to the difficult sealing problems in many industries such as chemical industry, real estate, electronics, and metallurgy. In the future use process, its advantages will continue to be discovered.

However, precisely because it is a relatively high-grade material in the field of plastics, there are shoddy PTFE sheet materials on the market. If we accidentally buy inferior PTFE sheets, it will bring great harm to our future use. trouble. So when buying, you must know how to identify the quality of PTFE board.

We can simply check first:

1. Color difference, if the high molecular weight PTFE board is uniform in color and not turbid, it is of better quality.

2. Anti-collision method, the simple operation is to hit with a hammer, there will be no cracks or pits.

3. Touch method, if the surface of the PTFE sheet is smooth without roughness, it is an excellent product.

In addition, we can check whether its quality is qualified from several properties of electrical insulation, oxidation resistance and high temperature resistance. Some inspection equipment and tools are needed. For example, insulation can be identified by high-voltage testing equipment, oxidation resistance can be tested by aging box, and as for high temperature resistance, its temperature resistance level can be seen only by high temperature flame.
