PTFE Micropowder [Polytetrafluoroethylene, (C2F4)n, APS <5um, Purity: 99.9%]

PTFE Micropowder is a finely powdered form of Polytetrafluoroethylene (PTFE), a high-performance fluoropolymer widely known for its non-stick, chemically resistant, and low friction properties. PTFE is most commonly recognized by the brand name Teflon, and when reduced to a fine powder (micropowder), it retains its beneficial characteristics while offering additional versatility in various industrial and consumer applications.

PTFE micropowder is manufactured by finely grinding PTFE resin through mechanical processes or chemical treatments to achieve micronized particles, typically in the range of 1 to 100 microns. The result is a white, dry powder with extremely low surface energy, making it highly suitable for applications where slipperiness, anti-friction, chemical resistance, and non-stick properties are required.

Key Properties

Appearance: White, fine powder

Chemical Resistance: Excellent resistance to most chemicals, acids, and bases

Thermal Stability: Stable at high temperatures (up to 260°C in continuous use, higher for short periods)

Low Friction: Reduces friction significantly between surfaces

Non-stick: Prevents substances from sticking to treated surfaces

Insolubility: Insoluble in most solvents and resistant to oxidation

Dielectric Properties: Excellent electrical insulating properties

Manufacturing Process:

PTFE micropowder is produced by several methods, primarily involving the micronization of PTFE resin. The process typically includes:

Mechanical grinding or milling of PTFE granules into very fine particles.

Chemical treatments or modifications to further reduce particle size and improve dispersion capabilities in various formulations.

Sieving and filtration to ensure uniform particle size distribution.
