| 摘要 |
<p>Articles fabricated from certain high molecular weight high density polyethy lenes (HMW-HDPE) combined with a second component, exhibit superior puncture propagation tear resistance and puncture propagati on tear length. The second component may be an elastomer such as styrene-butadiene-styrene, styrene-isoprene-styrene, EPR, EPDM, butyl rub ber, metallocene-calatyzed polyethylene, and combination s thereof. The second component or components will be present in a fabricated article from 1 to 15 weight percent. Articles include fi lms, bags made from films, and extrusion blow-molded articles.</p> |
