PFA Pellet SF-3302 with MFR 2.6-6
Product Description
PFA is the copolymer of TFE and PPVE, with excellent chemical stability. electrical insulating property, age resistance and low friction. Its high temperature mechanical property is much higher than PTFE and can be processed as common thermoplastics.
