Polypropylene (PP) extruded sheet yog ib daim ntawv yas ua los ntawm kev ntxiv PP rein rau ntau yam khoom siv ntxiv los ntawm extrusion, calendering, txias, txiav thiab lwm yam dab. PP Board yog ib qho khoom siv semi-crystalline. Nws yog qhov nyuab dua thiab muaj ntau tshaj qhov taw qhia txog pob txha tshaj PE. Txij li thaum ntsuas kub ntawm homopolymer PP yog qhov cuab zog heev thaum nws siab dua 0 ° C, ntau cov ntaub ntawv PP yog cov qauv copolymers ntawm 1 mus rau 4% ethylene los yog ib tug clamp copolymer uas muaj feem ntau ntawm ethylene. Cov tshuaj copolymer PP cov khoom muaj cua kub tsawg (100 ° C), tsis muaj transparency, tsis tshua muaj gloss, tsis muaj rigidity, tab sis muaj zog muaj zog.
