Production and Application of Polytetrafluoroethylene Raw Ma
Polytetrafluoroethylene raw tape is a high-performance sealing material ， Commonly used for waterproofing 、 moisture-proof 、 insulation 、 Corrosion resistance and other fields 。 Next, let’s take a detailed look at the production and application of polytetrafluoroethylene raw material tape 。
Production process
The production process of polytetrafluoroethylene raw material tape mainly includes the following steps ：
1） Raw material preparation ： Polytetrafluoroethylene resin is prepared from polymerized polytetrafluoroethylene monomers ， Its preparation requires the use of special catalysts and conditions 。 When preparing PTFE raw material tape ， It is necessary to prepare polytetrafluoroethylene resin into sheet material first 。
2） Mixed colors ： Normally ， PTFE raw material tape is white ， But sometimes it is necessary to dye or print labels ， This requires mixing the pigment into polytetrafluoroethylene resin ， To complete the preparation of colors 。
3） Processing and rolling ： Process the mixed polytetrafluoroethylene sheet material through rolling processing ， Produce the required thin sheets 。
4） Made into a strip shape ： Cut the processed PTFE sheet into strips of a certain width ， PTFE raw material tape 。
application area
Polytetrafluoroethylene raw tape can be widely used in the following fields ：
1） waterproof 、 moisture-proof ： Due to its excellent corrosion resistance and chemical resistance, polytetrafluoroethylene ， Polytetrafluoroethylene raw material tape can be used in hydraulic engineering 、 Waterproofing for chemical plants and other occasions 、 moisture-proof 。
2） insulation ： Polytetrafluoroethylene raw tape has excellent insulation performance ， Insulation materials that can be applied to power equipment 。
3） High temperature resistance ： The temperature range for the use of polytetrafluoroethylene raw tape is -180℃~+260℃ between ， Can be applied for sealing and protection in high-temperature environments。
