This is welding rod in PFA, the purest and most temperature resistant of the fully fluorinated fluoropolymers. HP in the name means high purity, a grade developed where purity is decisive, for example in semiconductor manufacturing.

The rod is used to join and seal PFA layers when linings and sheets are welded together. We have no data sheet of our own for the welding rod itself, so we put no measured values on this item and stay with the known properties of the material.

The rod is supplied in natural and is fed into a hot air welder. The high purity makes it suitable where the weld joint too has to be clean. Do you have a specific application in mind? We will help you choose right.
