The expanded teflon sheets are produced through a process called peeling, which involves cutting thin layers of teflon from blocks of solid material. The stripped layers are then stacked and compressed to create sheets with uniform thickness and extended structure.
The process to produce expanded teflon sheets consists of the following steps:
1. Preparation of Teflon resin: The first step is to mix the teflon resin with lubricants and filling materials. Lubricants help reduce friction during the scratching process, while filling materials improve the strength and durability of the final product.
2. Peeling: The prepared Teflon resin is then cut thin layers of material from the solid block using a special machine. The thickness of the peel layer can be adjusted to create a sheet with the desired thickness and density.
3. Stack: The stripped layers are then stacked on top of each
Other to form sheets of even thickness. The way these layers are arranged creates a uniform and extended structure.
4. Compression: A hydraulic press is then used to compress the stacked layers to create sheets of consistent density and thickness. The compression process also helps fuse the layers together to create a sturdy and durable material.
5. The final step is to finish the expanded teflon sheet and trim it to the desired size and shape. The sheet can also be treated with a special coating to improve its chemical and wear resistance.
Overall, the process of producing expanded teflon sheets is complex and requires specialized equipment and expertise. However, the resulting material is highly versatile and can be used in a wide range of applications, including gaskets, seals and insulation.
