Polyurethane maualuga fa'afuga meafaigaluega.O le umi lava o lepolyurethanemea mata'ina vaega (vaega isocyanate ma vaega polyether polyol) fa'ailoga fa'atinoga e fetaui ma mana'oga fua.E ala i nei meafaigaluega, e mafai ona gaosia toniga ma oloa foam agavaa.O le polyether polyol ma le polyisocyanate o loʻo faʻafefe e ala i vailaʻau i le i ai o ni vailaʻau faʻapipiʻi eseese e pei o le faʻafefe, faʻamalosi ma emulsifier e maua ai.polyurethanepua'a.
E mafai ona faʻaaogaina le masini faʻafefe o le Polyurethane mo le teuteuga o totonu o le taʻavale, faʻafefeteina puipui puipui, gaosiga o paipa faʻafefeteina, uila uila ma uila afi omomi, ma isi.

Vaega

1.O meafaigaluega e masani ona faʻaaogaina mo le gaosiga o paipa faʻafefete vevela, laupapa faʻamalama vevela, pusaaisa ma isi oloa e maualuga le PU i totonu.put.
2. O meafaigaluega nei ua faʻapipiʻiina ma faʻaulufaleina mai le pamu mita faʻapitoa, faʻapipiʻi maneta ma Siamani maualuga-saʻo flowmeter, faʻatasi ai ma le maualuga o le tui saʻo ma toe fai.
3.O meafaigaluega e faʻaaogaina le PLC ma faʻapipiʻiina i se tagata-masini faʻaoga, lea e mafai ona mataʻituina le faʻaogaina o meafaigaluega uma, faʻamasino aunoa pe a le masani, ma tuʻuina atu faʻamatalaga faʻamaonia;e faʻaaogaina le faiga faʻatonutonu saogalemu Siamani ma faʻapipiʻiina i galuega faʻamaumauga o gaosiga.
4.E mafai ona faʻalauteleina lenei meafaigaluega i se faiga faʻapipiʻi tele-tip e faʻaitiitia ai tau faʻaoga.

Polyurethane earplugs e lelei lemu le toe fa'aleleia o uiga, lea e mafai ona fetaui lelei ma alavai taliga o tagata ma fa'atino ai le fa'aitiitia o le pisa.E mafai lava ona e faia se su'ega toe fa'agesegese i luga o fusi taliga, oomi fa'amalosi taliga, ma mata'ituina le toe fa'asolosolo malie o fusi taliga pe a uma ona tu'u.E mafai ona faʻalauteleina ma toe faʻaleleia i se taimi puupuu.O lona malu ma le manava e sili atu, ma e sili atu le faʻalelei e ofuina.
