What is the difference between PTFE wire and PFA wire

What is the difference between PTFE wire and PFA wire ?

The biggest difference between the two is that PFA wire insulation melting point is low, and its melting point fluctuation range is wide, unstable, and PTFE wire has a fixed melting point.


One of the best features of PTFE wire is that when it is in a high temperature environment of 327 ° C and below, PTFE wire will not be affected in any way, even when the temperature is higher than the melting point, its outer insulation will not drop down and only become soft; When the temperature is below the melting point, the outer insulation will return to its original state.

The PFA wire in a short time at 320℃ high temperature, the insulation layer will burn and melt, and drop down, when the burning insulation layer drops on some combustible above, it is easy to cause a fire, resulting in a large area of human, material and financial losses.
