💧 PTFE Dispersion Comparison & Application Guide
— Three Leading High-Performance Fluoropolymer Dispersion Systems
Polytetrafluoroethylene (PTFE) dispersions are well known for their chemical inertness, high-temperature resistance, low friction coefficient, and non-stick characteristics.
They are widely applied in non-stick coatings, electrode binders, fabric impregnation, and high-end composite surface modification.
Below is a comprehensive comparison of three mainstream PTFE dispersions in terms of application scope and key performance parameters.
