DuPont Selar® PT 4274 Polyester Barrier Resin (discontinued **)
Categories:	Polymer; Film; Thermoplastic; Polyester, TP; Polyester Film
Material Notes:	Selar® PT 4274 is a toughened homopolymer polyester resin in the high melt viscosity (HMV) series designed for thermoplastic processes. The HMV modification changes the rheology of the melt and provides better processibility in extrusion operations. It can be processed in conventional extruders designed for polyolefins or polyesters.
