Therefore, the decrease of TG curve in Fig. EVOH copolymer is defined by the. • Mechanical strength ETFE is good. AGC Fluon® C-88AXMP ETFE. [2] Fluorinated ethylene propylene was invented by DuPont and is sold under the. ETFE; Cylinder Temperature, °. PCTFE or CTFE (originally known as Kel-F*) has many of the properties similar to other fluoropolymers such as PTFE, FEP or PFA, but is mechanically superior in rigidity (does not deform easily), and has very low gas permeability . Fluon ® LM-ETFE resins are modified to provide a 30 °C to 40 °C lower melting point than conventional ETFE resins. For determining melt point and then selecting suitable extruding temperature, thermal analysis was performed (Fig. In fact, they differ significantly only with regard to cold flow (PFA. 67–1. Though neither the XL-ETFE nor the ETFE performs very well at temperatures over 200 o C (482 o F), the XL-ETFE will last longer in hotter environments. Density: 1,67 - 1,75 g/cm³. It is processable by conventional extrusion, injection molding, roto.
