Although we all know that polytetrafluoroethylene expansion board products have a long service life, how long is the service life? Many people may not particularly understand, so, below, we will use polytetrafluoroethylene expansion. Take the board as an example, let me introduce to you the service life of PTFE products.

　　The service life of the PTFE Expanded Sheet is very long, because the PTFE Expanded Sheet is a plate-shaped tetrafluoroethylene product processed by a special process of the PTFE material. Many materials with excellent performance, including high temperature resistance, can be used at a temperature of 200~260 degrees for a long time; low temperature resistance.

　　Any product will expand and contract with heat, and PTFE Expanded Sheet is more likely to expand and contract with heat, and the expansion coefficient of PTFE Expanded Sheet is about ten times that of steel. Therefore, PTFE board is subject to temperature changes. , will have a relatively large impact on the size of the PTFE sheet.

　　It is worth noting that although the PTFE Expanded Sheet will be slightly deformed by the influence of heat and cold, its intrinsic quality will not change, that is to say, the performance of the PTFE board will remain unchanged, and the service life will naturally be shorter. will not change.
