Ecolek Sleeving



There has been general movement away from PVC materials in several industries due to problems with halogens, particularly in a fire hazard situation. This pressure has led to the development of Ecolek sleeving, which is a low smoke and fume, zero halogen, PVC replacement material. It is a thermoplastic that is both halogen-free and fire retardant but in many other aspects displays similar properties as PVC, has a similar look and feel, and can be used in the same applications.
