Jilama fila{0}}component foaming material ka teli ka kɛ a yɔrɔ A (isocinanate component) ani component B (polyol component) ye. O ɲagaminen kɔfɛ, o yɔrɔ fila bɛ ɲɔgɔn sɔrɔ walasa ka fomu bɔ. Ninnu ye sɛgɛsɛgɛli kɛrɛnkɛrɛnnen ye:
1.Component A ( .Isocyanate yɔrɔ .)
• A yɔrɔ kolomaw : poliizosiyanatiw, minnu ka ca, olu ye toluyɛni diizosiyanati (TDI) ani difenilimetani diizosiyani (MDI) ye, ka fara MDI polimɛriki (PAPI) kan.
• Baarakɛcogo : I n’a fɔ "crosslinking agent" min bɛ kɛ waleyali la, a bɛ jaabi ni hidrɔzɛni kulu baarakɛta ye yɔrɔ B kɔnɔ ani a ye fɛn ye min bɛ kɛ ka ɲɛsin fomu jɔcogo ma.
2.Component B (polyol component) .
A kɔnɔfɛn suguya caman bɛ sɔrɔ minnu bɛ u sen don wale la ani ka fomu cogoyaw labɛn:
• Poliyɔliw : i n’a fɔ poliyetɛri poliyɔli ni poliyɛsitɛri poliyɔli, minnu bɛ hidroksili ({0}}OH) di ani ka u kɛ ni isosiyanati kulu-NCO ye, o bɛ kɛ fomu kolosinsinnan basigilen ye.
• Foaming agent : A bɛ gazi bɔ walasa ka ɲagami in bonya ani ka bugunw dilan. A ka ca a la, a bɛ sɔrɔ fomuw farikolo la (misali la, Freon substitutes, cyclopentane) ani kemikaliw (misali la, ji, min bɛ kɛ ni isocyanate ye walasa ka gazi ɲuman sɔrɔ).
• Katalisita : A bɛ faritanabana teliya, i n’a fɔ amine katalisita (promotes foaming reaction) ani organotin catalyst (promotes gel reaction).
• Surɔfɛnw : Aw bɛ fomu jɔcogo sabati ani ka fogonfogon bali ka pɛrɛn. A ka c’a la, u ye silɔkisanw ye.
• Fɛn wɛrɛw : i n’a fɔ tasumafagalanw, fasaw, kulɛriw, a ɲɔgɔnnaw, minnu bɛ fara a kan ka kɛɲɛ ni a kɛcogo ye walasa ka tasumafagalan, a fanga ani a nafa wɛrɛw ɲɛ.

Ni a yɔrɔ A ni B ɲagamina, isosiyanati kuluw bɛ u kɛ ni-OH kulu ye poliyɔli ni ji kuluw la, gazi bɔli (foaming) ka kɛ fomu porose ye. O yɔrɔ kɛrɛnkɛrɛnnenw ni u suguya suguyaw bɛ fomu ka density (dansi) density (dansi), a ka gɛlɛn, a ka thermo insulation (sumaya) ani a ka jogo wɛrɛw de bɛ a jira.
