Edge ultra sonic kaw welded foldable Hoobkas nqi tiv thaiv cog PP Corrugated Corflute Tsob Ntoo Guard

Cov khoom siv copolymer-hom PP muaj qis dua thermal distortion kub (100 ° C), tsis muaj pob tshab, tsis tshua muaj gloss, tsis tshua muaj rigidity, tab sis muaj zog cuam tshuam lub zog.Lub zog ntawm PP nce nrog nce cov ntsiab lus ethylene.Vicat softening kub ntawm PP yog 150 ° C.Vim muaj cov qib siab ntawm crystallinity, cov khoom siv no muaj qhov tawv tawv zoo thiab khawb tsis kam.PP tsis muaj teeb meem kev ntxhov siab ib puag ncig.Feem ntau, PP yog hloov kho los ntawm kev ntxiv iav fibers, hlau additives los yog thermoplastic roj hmab.Tus nqi ntws MFR ntawm PP yog li ntawm 1 txog 40. PP cov ntaub ntawv uas tsis tshua muaj MFR muaj kev cuam tshuam zoo dua tab sis qis dua ductility.Rau tib cov khoom siv MFR, lub zog ntawm cov hom copolymer yog siab dua li homopolymer hom.Vim crystallization, qhov shrinkage ntawm PP yog siab heev, feem ntau 1.8 ~ 2.5%.Thiab cov kev taw qhia sib xws ntawm shrinkage yog zoo dua li ntawm PE-HD thiab lwm yam ntaub ntawv.Ntxiv 30% iav additive tuaj yeem txo qhov shrinkage rau 0.7%.
