This specification covers melt processible molding and extrusion materials of modified ETFE-fluoropolymer. The ETFE resin is a copolymer of ethylene containing approximately 75 mass% of tetrafluoroethylene. This specification addresses virgin materials only as performance requirements cannot be met with recycled material. Modified ETFE-fluoropolymers shall be supplied in pellet form and classified into five types according to their specific gravity. Furthermore, the resins of each type are divided into three grades according to their melt flow rate. Materials shall be sampled, prepared, and conditioned as appropriate for testing, wherein the following performance requirements must be met: melting point and flow rate; melting endotherm peak temperature; specific gravity; tensile properties (tensile strength and elongation); and dielectric constant and dissipation factor.
