DY-9 is a kind of powdered VDF homopolymer with low melt mass flow rate, and is in the category of thermoplastic fluororesin. This resin can resist most of the chemical media with characteristics of superb heat resistance, high mechanical strength, high wear resistance, UV resistance and radiation resistance. DY-9 can be used as bonder of lithium battery.
VDF homopolymer starts slight decomposition when temperature is above 300℃ and gives off hydrogen fluoride gas.
