- Mbali ya “A”: Izi nthawi zambiri zimakhala ndi diphenylmethane diisocyanate (MDI) ndi diphenylmethane diisocyanate (pMDI) yomwe imapangidwa ndi polymer.
- Mbali ya “B”: Iyi ndi njira yosakanikirana ya ma polyol, ma catalyst, ma thovu, ma flame retardants, ndi ma surfactants. Ma catalyst omwe amagwiritsidwa ntchito mbali ya “B”, mongaMXC-C15ndi MXC-T, zimathandiza kwambiri pakuonetsetsa kuti thovu likuchita bwino komanso kuti lipangidwe bwino.
