Petroquimica Triunfo Trithene® TX 7001 LDPE - High Molecular Weight  (discontinued **)
Categories: Polymer; Film; Thermoplastic; Polyethylene (PE); Low Density (LDPE)

Material Notes: The Trithene TX 7001 resin is a low-density polyethylene (LDPE) with high molecular weight, designed to satisfy those applications that require high mechanical strength and environmental stress cracking resistance (ESCR), together with good processability, proper of branched polyethylene produced by a high-pressure process. Due to its easy welding quality, this product fits all requirement of automatic or semi-automatic cutting, welding and/or packaging lines, contributing to lower losses due to packaging rupture. Trithene TX 7001 resin presents an excellent performance in conventional LDPE extruders, granting low energy consumption during the whole process and allowing the production of packaging with a good dimensional uniformity and an excellent surface finishing. This product complies with ASTM standard D1248-IA5 and the requirements of Brazilian and corresponding legislation of Mercosul and it is in conformity with FDA Regulations 21 CFR 177.1520 (c) 2.1, to contact with foodstuff.

Applications: High resistance films for industrial packaging, shrink films, multi-duty plastic tarpaulins, etc. Flexible tubes and hoses. Blow mold parts: house and industrial-use chemical containers.

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.
