E-CTFE
Because of its excellent resistance to permeation by gases, E-CTFE is commonly used as a coating material for chemical containers and pipes in the process industry. The material retains its impact strength even at temperatures as low as -76 °C. It is suitable for high‑purity applications in the semiconductor industry, for example. We deliver E-CTFE as plastic rods, sheets, hollow rods and as welding filler material.
