Resistivity

Resistivity

(OP)
How does resistivity react to regrind Peek polymer in processing? That is compared to the resistivity of virgin msterial

RE: Resistivity

Tramp contaminants in regrind will tend to reduce resistivity compared to virgin material.

RE: Resistivity

Resistivity has a percolation behavior with concentration of your impurity. That means that even adding something conductive like carbon black will have almost no effect on resistivity until you have enough carbon black so that the particles touch and form a circuit. That means 10 or 20% by volume. So, resistivity should be a very insensitive way to look for contamination. Better would be FTIR, for example.
