Polytetrafluoroethylene (PTFE) bushings are crucial components in a variety of industries, valued for their exceptional properties and versatility. PTFE is a high-performance fluoropolymer known for its remarkable combination of low friction, chemical resistance, and thermal stability. PTFE bushings are designed to provide a reliable and low-friction interface between moving parts in mechanical systems, making them invaluable in numerous applications across diverse industries.

Properties and Characteristics

PTFE, often referred to by the brand name Teflon, possesses several key properties that make it an excellent choice for bushing applications:

• Low Friction: PTFE has an exceptionally low coefficient of friction, even in dry conditions. This property reduces wear and energy consumption, contributing to the efficiency and longevity of mechanical systems.

• Chemical Resistance: PTFE is highly resistant to a wide range of chemicals, acids, and solvents, making it suitable for applications where exposure to corrosive substances is a concern.

• Thermal Stability: PTFE can withstand a wide temperature range, from extremely low temperatures to high temperatures without significant loss of its mechanical properties. This property makes PTFE bushings suitable for both cryogenic and high-temperature applications.

• Low Moisture Absorption: PTFE has low moisture absorption, ensuring dimensional stability even in humid environments.

• Electrical Insulation: PTFE is an excellent electrical insulator, making it suitable for use in electrical and electronic applications where electrical isolation is required.

• Self-Lubrication: PTFE bushings can be impregnated with lubricating fillers or additives to provide self-lubricating properties, reducing the need for external lubrication.
