Maa'a'a foam mea autu Fa'atau oloa, atina'e ma fa'aoga fou ole polyurethane, phenolic resin, PET, PVC, SAN, PES ma isi mea foam.
O le fatu foam fausaga o se mea tu'ufa'atasi, e masani lava o se polymer thermoset (ae mafai ona avea ma se thermoplastic) tu'ufa'atasia ma se kesi fa'aletino (e pei o le nitrogen) po'o se vaila'au feula i le taimi o le fa'agasologa.O le taunuuga e le o se mea mautu, ae o se microcellular foam maualalo maualalo faʻatasi ma se atigi maualuga.
O le foam core e fa'aitiitia ai le mamafa atoa o le meafaitino, a'o le pa'u mautu e malosi ma fa'asa'o.O le fausaga o meafaitino e pei o se sanuisi, faʻatasi ai ma se pito maualalo maualalo o loʻo siomia atoa e se paʻu maualuga.Ona o lona uiga fa'apitoa, o 'a'ai fa'afu'a fa'amalo e masani lava e 20% i le 40% mama nai lo polymers mautu, alumini, sila, fa'ameamea fa'apipi'i, po'o isi mea e masani ona fa'aaogaina.Ona o lona natura itiiti le malosi, o mea faʻavae e faʻaaogaina e fai ai foam fausaga e masani lava o polymers thermoplastic nai lo thermosets.E masani ona fa'aaogaina thermoplastics e aofia ai, ae le gata i: polyurethane, polycarbonate, polyphenylene ether (Noryl), polybutylene terephthalate (Valox) ma le acrylonitrile butadiene styrene ma isi mea autu foam: polyurethane, phenolic Resin, PET, PVC, SAN, PES foam e fai ma sui. oloa, pisinisi ma talosaga fou.
Polyurethane foam core ua faia mai le CFC free foamed polyurethane, o se pupuni tapunia e mafai ona maua facestocks, laupapa ma oloa masani o densities eseese ma mafiafia, ae maualuga density, mu retardant malo polyurethane foam pepa Laau, poloka po o moldings o loo maua foi.Tau-lelei, fefiloi ma umi.E ui o mea faʻavae o le polyurethane foam cores atonu e le talafeagai mo faʻaoga sili atu ona manaʻomia, e faʻaaogaina lautele e faʻateleina ai le mafiafia, fatuina foliga faʻalava, faʻaogaina lelei, ma faʻafefe.
Polyurethane foam cores o se filifiliga autu maualalo tau mo tagata gaosi mea tu'ufa'atasi.O le foam polyurethane malosi e fa'aaogaina mo le fa'afefeteina, fa'a'ese'ese po'o le avea ma mea autu e pei o le fa'atuputeleina o le gataifale, fa'au'u ma isi fa'aogaina o le fa'aogaina o le gataifale.
