METHOD OF EXTRUSION MOLDING OF POLYPROPYLENE |
| 摘要 |
<p>PURPOSE:By extruding a polypropylene base incorporated with an extremely high molecular weight polypropylene in a specific temperature range the melt fracture point on the extrusion molding is raised and the critical shear rate is increased extrensively to improve the high-speed extrusion molding property.</p> |
