1. Overview of Raw Tape
Raw tape, also known as water tape, polytetrafluoroethylene (PTFE) tape or expanded polytetrafluoroethylene tape, is a sealing material widely used in various occasions that require acid and alkali resistance. It is mainly used at pipe joints to enhance the airtightness of pipe joints and prevent medium leakage. Raw tape is widely used in water treatment, natural gas, chemical industry, plastics, electronic engineering and other fields because of its non-toxic, odorless, excellent sealing, insulation and corrosion resistance.
2. Material characteristics of polytetrafluoroethylene (PTFE)
High and low temperature resistance: polytetrafluoroethylene has excellent high and low temperature resistance and can maintain the stability of physical and chemical properties under extremely high and low temperature environments. This makes the raw tape have excellent sealing effect under various temperature conditions.
Corrosion resistance: polytetrafluoroethylene has excellent corrosion resistance to a variety of chemical substances and can resist the erosion of strong acids, strong alkalis, organic solvents and other media. This makes the raw tape have a wide range of application prospects in the chemical industry.
Self-lubrication: PTFE has an extremely low coefficient of friction and self-lubrication, which can reduce wear between parts and reduce the level of operating noise. This feature makes the raw tape perform well on parts that need to rotate or slide frequently.
Surface non-stickiness: The surface of PTFE is non-sticky and does not easily adhere to dust and dirt. This makes the raw tape advantageous in terms of keeping clean and hygienic.
Insulation: PTFE has excellent insulation properties and can withstand high voltage without being broken down. This makes the raw tape widely used in the field of electronic engineering.
3. Types and applications of raw tape
According to different processes and requirements, PTFE raw tape can be made into various types of products to meet the requirements of different industries. For example, colored and high-density colored raw tape, PTFE raw tape for winding and sintering, and oily PTFE raw tape. These different types of raw tapes may differ in performance, but all have the basic properties of PTFE.
In terms of application areas, raw tape is widely used as auxiliary supplies in liquid pipeline installation, such as sealing of joints of water pipes, gas pipes, oil pipes, etc. At the same time, in occasions that need to withstand high temperature, high pressure or highly corrosive media, polytetrafluoroethylene raw tape with higher performance indicators should also be selected.
In summary, the main material of raw tape is polytetrafluoroethylene (PTFE), which has excellent high and low temperature resistance, corrosion resistance, self-lubrication, surface non-stickiness and insulation properties, making raw tape widely used in many fields.
