SPECIAL CHARACTERISTICS FOR THIS WIRE:

Normal PTFE wire insulation surface is very smooth, if need to make bonding this
Wire to other parts, it will cause the bonding adhesion is very poor.  Our etched 
PTFE wire is very strong in this fiend, after etching, the PTFE surface become rough 
and full of Small holes, it greatly improved bonding adhesion strength.
