Welding Rod in PFA HCR 4 mm natural
This is welding rod in PFA, a fully fluorinated fluoropolymer with very high chemical resistance and a high temperature ceiling. HCR in the name stands for high corrosion resistance, a grade that is extra resistant to corrosion.
The welding rod is used to join and seal joints when PFA sheets or linings are put together. We have no separate data sheet for the rod itself, so we state no measured values for this article and refer instead to the general chemical tolerance of the grade.
The rod is 4 mm in diameter and supplied in natural. It is fed into a hot air welder when fluoropolymer layers are to be joined tight. Do you need technical documentation? Call us directly.
