Ethylene Tetrafluoroethylene (ETFE) finds its application across various sectors owing to its unique characteristics. ETFE is a high-strength fluorine plastic exhibiting excellent heat resistance (a continuous use temperature range of -200 to 165 °C), outstanding electrical properties, weatherability, and chemical resistance.
Alfa Chemistry has harnessed these benefits to develop ETFE extruded films, which push the technological boundaries of industrial applications. Alfa Chemistry offers high performance ETFE extruded films in various grades including premium grade (PG) and mold release (MR).
