Polyurethane foaming agents chigadzirwa chemuchinjika-kuisirwa fetireza tekinoroji yeaerosol nefoam tekinoroji yepolyurethane. Anogadzirwa ari ese machubhu nepfuti, achiratidza chipanje-sechimiro. Foaming agents anoshandiswa mukugadzira microporous foam mapurasitiki anowanzo kuiswa mumhando mbiri: yemuviri nemakemikari. Uku kupatsanurwa kunobva pakuti chizvarwa chegasi inzira yemuviri (kureva, kuvhuvhuta kana kuderedzwa) kana muitiro wemakemikari (kureva, kuparadzwa kwemakemikari zvimiro kana mamwe maitiro emakemikari).
Polyurethane foaming agent, inozivikanwawo se single-component polyurethane foam sealant, inowanzonzi foaming agent, foaming adhesive, kana PU sealant. Izwi rechirungu rekuti PU FOAM chigadzirwa chemuchinjiko-kubatanidzwa kwehunyanzvi hweaerosol uye tekinoroji yefoam yepolyurethane. Icho chinhu chakakosha che polyurethane chigadzirwa chine polyurethane prepolymer, foaming agent, catalyst, uye zvimwe zvikamu muakamanikidzwa aerosol can. Kana zvinhu zvacho zvapfapfaidzwa kubva mugaba reaerosol, iyo foamy polyurethane zvinhu inokurumidza kuwedzera uye inopindirana nehunyoro mumhepo kana substrate yainosangana nayo kuita furo. Iine huwandu hwakawanda hwekushandisa. Ine zvakanakira pre-kupupa furo, kuwedzera kukuru uye kudzikira. Iyo furo ine simba rakanaka uye yakakwirira kunamatira. Mushure mekurapa, iyo furo ine akawanda mhedzisiro senge kuzadza mapundu, kusungirira, kuisa chisimbiso, kupisa kupisa uye kunyudza inzwi. Inobatsira kwezvakatipoteredza uye ine simba{11}inochengetedza zvinhu zvekuvakisa zviri nyore kushandisa. Inogona kushandiswa kuisa chisimbiso uye kuvhara mavuza, kuzadza mapundu nekugadzirisa uye kusungirirana, kupisa kupisa uye kuvhara inzwi. Inonyanya kukodzera kuvhara uye kuvhara mavuza uye kudzivirira mvura pakati pesimbi yepurasitiki kana aluminium alloy magonhi nemahwindo nemadziro.
