Title:
ポリテトラフルオロエチレン水性分散体
Document Type and Number:
Japanese Patent JP7078441
Kind Code:
B2
Abstract:
Provided is a polytetrafluoroethylene (referred to hereinafter as "PTFE") aqueous dispersion that has exceptional long-term dispersion stability, does not allow the PTFE in a final product to separate even when added to a liquid material such as a paint, can succeed in imparting the functions of PTFE in a desired final form, and has exceptional productivity economically. This PTFE aqueous dispersion is characterized by containing 10-70% by mass of fine particles of PTFE that have a primary particle diameter of 0.03-0.3 μm and a number-average molecular weight Mn of 10,000-30,000, also containing 0.5-20% by mass of a dispersant relative to the fine particles of PTFE, the foam volume ratio being less than 10 vol%, and the average particle diameter by dynamic light scattering being less than 300 nm.
