ABS thiab PVC yog ib txwm amorphous thermoplastics. Semi-crystalline polymers muaj cov qauv molecular heev. Cov no tsis soften li qhov kub thiab txias, tab sis theej muaj ib tug txhais thiab nqaim melting point. Cov ntsiab lus melting no feem ntau yog siab tshaj ntawm cov kab mob siab tshaj ntawm amorphous thermoplastics.
YPuas yog PP semi-crystalline lossis amorphous?
Semi-Crystalline Thermoplastics: Cov no feem ntau ntawm koj cov yas yas thaum koj xav txog cov yas "qhov". Lawv suav nrog tsev neeg polyethylene (LDPE, HDPE, UHMW-PE), Polypropylene, nylon, acetal thiab fluoropolymers.
YPuas PMMA amorphous lossis semicrystalline?
Cov khoom siv xws li polystyrene (PS), polycarbonate (PC), acrylics (PMMA), acrylonitrile-butadiene styrene (ABS) thiab polyvinyl chloride (PVC) tau hais tias yog amorphous thermoplastics.
YPuas HDPE amorphous lossis crystalline?
Cov thermoplastics nrov siv hauv kev lag luam ntim khoom xws li HDPE thiab polypropylene, tau muab cais ua ib nrab-crystalline, thaum lwm tus xws li polystyrene thiab ABS, suav tias yog amorphous.
YIs PETG amorphous?
Polyethylene Terephthalate Glycol (PETG) yog an amorphous variation of PET.
