PP ntawv yog ua los ntawm polypropylene cob raws li cov ntaub ntawv tseem ceeb, ntxiv ntau hom txheej txheem xim masterbatch, toughening agent thiab brightening tus neeg sawv cev. Nws yog tsim los ntawm sib tov, pov rau extrusion, peb-yob calendering, txias, kos duab thiab ntoo. . PP daim ntawv muaj cov yam ntxwv ntawm cov khoom tsis zoo, tsis muaj ntxhiab, kev kho siab, siab ua kom muaj zog thiab cov cuab yeej zoo, thiab siv tau rau kev lag luam hauv kev lag luam xws li kev lag luam, kev ua liaj ua teb thiab txiv hmab txiv ntoo. Qhov saum npoo ntawm lub phaj ua los ntawm PP cov ntawv tua tsiaj xa dej yog tus zoo nkauj thiab zoo nkauj, thiab zoo txais los ntawm cov neeg siv. Daim ntawv PP kuj yog tsim rau cov khoom ntim ntawm cov khoom noj uas muaj high-resistant, xws li cov khov nab kuab, cov thawv ntim ntawm dumpling, cov thawv ntim thiab lwm yam.
PP yas muaj: kev tiv thaiv zoo, zoo nkauj, cov ntaub qhwv npog luam ntawv, Lub Yin, bronze, kub tsis kam, tsis tshua muaj siab kub, tsis muaj zog, ua rau cov khoom noj khoom haus ntsuas (tsis tas yuav tsum tau), microwave.
Disadvantages ntawm PP: qhov tsis tshua muaj siab, tsis txaus, tsis zoo, huab cua tsis haum, yooj yim los ua "tooj liab puas tsuaj", nws muaj ib tug post-shrinkage phenomenon, tom qab demolding, yooj yim rau hnub nyoog, ua brittle, yooj yim deform.
