Halar is a specialty expandable braided sleeving, made of a Ethylene-Chlorotrifluoroethylene copolymer monofilament.
The material is extremely tough and durable and has even been approved by NASA for use in space programs.
It has a continuous temperature rating at 150C , increasing the efficiency of its use. Versus a Teflon material, Halar braided sleeving is an excellent substitute if seeking something comparable but more affordable.
