Description
PTFE Nanopowder / Nanoparticles
Chemical Formula: (C₂F₄)ₙ | Purity: 99.9% | Average Particle Size (D50): 260 nm | CAS Number: 9002-84-0
Product Overview
Polytetrafluoroethylene (PTFE), commonly known under brand names like Teflon®, is a high-performance fluoropolymer renowned for its exceptional chemical resistance, low friction coefficient, and thermal stability. In nanopowder form, PTFE offers increased surface area and dispersibility in various matrices, making it ideal for high-tech and advanced manufacturing applications.
PTFE nanoparticles retain all the outstanding properties of bulk PTFE — such as non-stick behavior, electrical insulation, and thermal resistance — while enabling integration into nanocomposites, coatings, and functional films at the micro- and nano-scale.
