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.
First of all, use "three good" to weigh whether the value of PTFE Expanded Sheet is not worth choosing.There are many good garment packaging machines in the industry, and many people evaluate whether the PTFE Expanded Sheet is worth choosing from the aspect of quality, and we must pay attention to not only the quality. Manufacturers may not care about any follow-up services, and there will be many such situations.
The molding of PTFE Expanded Sheet is divided into two stages. The process flow is as follows:(1) Mixing The PTFE Expanded Sheet resin and the extrusion aid are mixed uniformly according to a certain mass ratio. Using dispersing resin, it has good fiber-forming properties, and the cohesion between particles is low, and the molecular chain will be arranged along the long axis of the particles after a small shearing action, forming linear crystals.
