The cathodic protection industry is a rugged one, and cables used in CP applications need to be able to withstand extreme soil, water and gaseous environments: brackish water, corrosive liquids, harsh underground conditions.
CP Cables can have several layers of coating on them. In addition to the HMWPE layer (which can be used alone for CPC), one of the most important layers is fluoropolymer insulation, which is often then covered with an HMWPE jacket. At Kris Tech, we use two different types of fluoropolymers: ECTFE (halar) and PVDF (kynar wire).
Stands for: polyethylenechlorotrifluoroethylene (say what?)
aka: Halar Wire (Solvay Solexis brand)
Description: Semi-crystalline melt-processable copolymer of ethylene and chlorotrifluoroethylene.
Stands for: polyvinylidene fluoride (that one’s a little easier)
aka: Kynar wire (Arkema brand), Hylar and Solef (both Solvay Solexis brands)
Description: Semi-crystalline melt-processable vinylidene fluoride based homopolymers and copolymers
We cover both of our products with HMWPE, and suggest Halar as the fluoropolymer of choice. Both of these insulation types significantly increase the level of durability of the CPC, making them much more reliable once installed in a cathodic protection system.
