Petroquimica Triunfo Trithene® CX 7020 LDPE - Cast Film
Categories:	Polymer; Film; Thermoplastic; Polyethylene (PE); Low Density (LDPE)
Material Notes:	The Trithene® CX 7020 resin is a low-density polyethylene (LDPE) with medium molecular weight, excellent processability, and low gel content. Those features allow a production of thin and highly uniform films. This product complies with ASTM standard D1248-IA3. Applications: Smooth or embossed films for diapers, disposable sheets, etc.; Films for lamination; Injection-Blow Molding. Resin Properties: Compressed molded plate. Method ASTM D-1928, procedure C. Film obtained on a 50mm blow film line with barrier screw, 25:1 L/D, 1.0mm die gap, 50µm gauge, 2.3:1 BUR. Information provided by Dax Resinas
Key Words:	FDA: 21 CFR 177.1520 (C) 2.1
