PTFE bolts and nuts

Material Characteristics: PTFE material boasts excellent corrosion resistance, capable of withstanding the侵蚀 of various strong acids, alkalis, and organic solvents. Consequently, PTFE bolts and nuts can operate stably for a long time in corrosive environments such as chemical industries. High-Temperature Resistance: PTFE bolts and nuts exhibit superior high-temperature properties, generally maintaining their physical properties within a temperature range of -196°C to +260°C, and can even withstand higher temperatures for short periods.

Material characteristics

  1. Corrosion resistance：

  • PTFE materials boast excellent corrosion resistance, capable of withstanding the侵蚀 of various strong acids, bases, and organic solvents. Consequently, PTFE bolts and nuts can operate stably for extended periods in corrosive environments such as chemical industries.

  • High-temperature resistance：

    • PTFE bolts and nuts offer excellent high-temperature resistance, typically maintaining their physical properties within a temperature range of -196°C to +260°C, and can even withstand higher temperatures for short periods without damage (as some sources indicate they can endure temperatures up to 300°C for brief durations). This makes them widely applicable in high-temperature environments.

  • Non-stick：

    • PTFE has a low surface tension and excellent non-stick properties, allowing almost all materials to resist sticking to the PTFE coating. This characteristic makes PTFE bolts and nuts less prone to accumulating impurities during fluid transfer, maintaining cleanliness.

  • Low coefficient of friction：

    • PTFE has a low coefficient of friction, typically between 0.05 and 0.15, making PTFE bolts and nuts more smooth during connection and disconnection, reducing friction and wear.
