Piv nrog rau lwm cov yas uas lwj tau, PBS muaj cov khoom siv kho tshuab zoo heev, ze li PP thiab ABS yas; nws tiv taus cua sov zoo, nrog rau qhov kub hloov pauv cua sov ze li 100 ℃, thiab qhov kub hloov pauv ze li 100 ℃, uas tuaj yeem siv rau kev npaj cov pob dej haus kub thiab txias thiab cov thawv noj su, thiab kov yeej qhov tsis zoo ntawm lwm cov yas uas lwj tau hauv qhov kub tsis kam kub;
Kev ua haujlwm PBS zoo heev, tuaj yeem siv rau hauv cov khoom siv ua yas dav dav rau txhua yam kev ua molding, PBS tam sim no yog qhov zoo tshaj plaws ntawm kev ua haujlwm yas, tib lub sijhawm tuaj yeem sib xyaw nrog ntau cov calcium carbonate, hmoov txhuv nplej siab thiab lwm yam khoom sau, kom tau txais cov khoom pheej yig; PBS ntau lawm tuaj yeem ua tiav los ntawm kev hloov pauv me ntsis ntawm cov khoom siv polyester dav dav uas twb muaj lawm, tam sim no cov khoom siv polyester hauv tsev muaj peev xwm ntau dhau, kev hloov pauv ntawm kev tsim khoom ntawm PBS rau cov khoom siv polyester ntau dhau muab lub sijhawm zoo rau kev tsim khoom ntawm PBS. Tam sim no, cov khoom siv polyester hauv tsev muaj peev xwm ntau dhau, kev hloov pauv ntawm PBS ntau dhau rau cov khoom siv polyester ntau dhau muab kev siv tshiab.
