Polytetrafluoroethylene /PTFE corrugated packing plate main performance: there are small holes on the packing sheet, with large energy, low pressure drop and high specific surface area, in improving output, improving energy consumption, improving efficiency has greater characteristics. At the same time due to the orderly arrangement of the packing, the solid particles contained in the material can be discharged through the corrugated bottom of the packing, so the anti-blocking performance is excellent, elastic than the general general tower, replacing the bulk tower packing, can increase the production capacity of 5%, increase the production efficiency of 50%. At the same time, it has the characteristics of light weight and low price, suitable for large volume tower. Polytetrafluoroethylene /PTFE corrugated packing products are mainly used in gas purification and separation purification and other industries. It has the advantages of light weight, large capacity, low pressure drop, high specific surface area and easy replacement. The relative molecular weight of POLYtetrafluoroethylene is large, low for hundreds of thousands, high up to 10 million, generally millions (polymerization degree in 10^ 4 order of magnitude, and polyethylene in 10^ 3). Generally, the crystallinity is 90~95%, and the melting temperature is 327~342C.
