Description
Luban DMDZ-6147 is high-density polyethylene with broad molecular weight distribution and high molecular weight. This product provides an excellent combination of extrudability and parison stability, which contribute to uniform wall thickness in large parts. The grade is ideal for blow molding containers such as the 5 – 55 gallon (20 – 210 lit) closed head shipping containers and other similar parts. The broad distribution also provides outstanding environmental stress crack resistance (ESCR) at a good rigidity. The smooth surface of molded parts is readily treated and printed for high quality applications.
Main Characteristics:
- Hexene High Density Resin
- Outstanding environmental stress crack resistance
- Excellent parison melt strength/ low sag
- Good extrudability/ processability
- Good rigidity
Application
Blow molding containers from 20 lit – 210 lit for packaging of industrial chemicals, latex paints, printing inks, foodstuffs, adhesives, and other chemical specialties
