CO-EXTRUDED FILM STRUCTURES OF POLYPROPYLENE IMPACT COPOLYMER WITH OTHER POLYMERS |
摘要 |
It has been discovered that the properties of sheet or film materials or structures can be improved by co-extruding a rubber-impact modified heterophasic copolymer core layer with at least a second polyolefin. The second polyolefin may be a Ziegler-Natta catalyzed polyethylene (ZN PE), Ziegler-Natta catalyzed polypropylene random copolymer (ZN PP RCP), a metallocene catalyzed polypropylene random copolymer (mPP RCP), a linear low density polyethylene (LLDPE) and/or a metallocene catalyzed medium density polyethylene (mMDPE). Improvements include, but are not necessarily limited to, reduced haze and increased gloss. These sheet or film materials may be co-extruded with other resins or laminated with other materials after extrusion. |
