フルオロポリマーブレンド方法
Document Type and Number:
Japanese Patent JP2009516068
Kind Code:
A
Abstract:
Aqueous dispersions on non-melt flowable PTFE and melt-fabricable perfluoropolymer are mixed together, followed by recovery of the resultant mixture of the dispersed particles of each of these polymers, and melt mixing of the resultant mixture of particles to obtain a blend in which the PTFE particles form the disperse phase and the perfluoropolymer forms the continuous phase, the melt mixing producing advantageous melt viscosities and the blend exhibiting advantageous physical properties even at high PTFE contents of about 30 wt %.
