HIGHLY RIGID PROPYLENIC RESIN AND BLOW MOLDED ARTICLE MADE THEREFROM |
| 摘要 |
A highly rigid polypropylene resin which has an MI of 0.1-1.2 g/10 min as measured at a temperature of 230 ~C under a load of 2,160 kg and satisfies t he following relationship between elongational viscosity, Y(Pas), and MI: 2.0 x 105 x MI-0.68 <= Y <= 8.0 x 105 x MI-0.68. The resin can provide large blown parts that are lightweight and excellent in rigidity, dimensional stability and thermal resistance, and has a good drawdown resistance.
