PTFE Lubricant Powder
A high-purity, ultra-fine powdered polytetrafluoroethylene (PTFE) lubricant, offering exceptional friction reduction and non-stick properties.
Description
Polytetrafluoroethylene (PTFE) Lubricant Powder (CAS 9002-84-0) is a finely divided, white particulate material renowned for its extremely low coefficient of friction and superior chemical inertness. This synthetic fluoropolymer, denoted by the chemical formula (C2F4)n, is characterized by its linear molecular structure composed entirely of carbon and fluorine atoms. The strong carbon-fluorine bonds impart outstanding thermal stability, allowing the material to withstand a broad temperature range from cryogenic to elevated temperatures without degradation. Its intrinsically non-polar surface exhibits excellent non-stick characteristics and hydrophobic properties, making it an ideal choice for dry lubrication applications where oils and greases are undesirable or ineffective. The small particle size of this powder enables its integration into various matrices, including plastics, elastomers, and coatings, to enhance their tribological performance. Furthermore, it is resistant to most chemicals, solvents, and acids, contributing to its longevity and reliability in harsh industrial environments. Its electrical insulating properties are also noteworthy, making it suitable for certain specialized applications.
Applications
PTFE lubricant powder finds extensive use across numerous industrial sectors due to its unique combination of properties. In the automotive industry, it is incorporated into brake pads, clutch facings, and various bearing components to reduce wear and improve operational efficiency. It serves as an internal lubricant and anti-stick agent in plastics and elastomers, enhancing their mold release characteristics and wear resistance. The textile industry utilizes it in coatings for fabrics and threads to impart water repellency and reduce friction. In the manufacturing of non-stick coatings for cookware and industrial equipment, PTFE powder is a primary component. It is also employed in dry film lubricants for gears, chains, and precision instruments where liquid lubricants cannot be used or would attract dust and dirt. Its chemical inertness makes it valuable in medical devices and pharmaceutical equipment, ensuring smooth operation and minimizing contamination.
Storage & Handling
Store in a cool, dry, well-ventilated area away from incompatible materials and direct sunlight. Keep containers tightly closed when not in use to prevent contamination and moisture absorption. Avoid generating dust during handling. Use local exhaust ventilation and appropriate personal protective equipment.
