Tivthaiv: DY2513 yog muaj los ntawm Cheebtsam ABC. Tivthaiv Ib tug yog polyol, B yog polyurethane prepolymer uas twb nrog isocynate, C yog saw extender.
Yam ntxwv: Qhov kawg khoom nyiam zoo los tiv thaiv kuj muaj peev xwm, zoo thaws. Thiab cov hardness yuav tau tom los ntawm qhov sib txawv ratio. Cov xim yuav yuav tom los xim.
Daim ntawv: Qhov no cov ntaub ntawv uas siv los mus tsim Polyurethane sieves, PU chais, tu npua (discs) thiab lwm yam elastomer.
