Flexible polyurethane foam (FPF) ipolymer inogadzirwa kubva pakuita kwe polyols uye isocyanates, chemikemikari yakatanga muna 1937. FPF inoratidzirwa ne cellular structure inobvumira imwe dhigirii yekumanikidza uye kusimba iyo inopa cushioning effect.Nekuda kweichi chivakwa, chinhu chinofarirwa mufenicha, yekurara, zvigaro zvemotokari, midziyo yemitambo, kurongedza, shangu, uye kapeti cushion.Inoitawo basa rinokosha mukudzivirira inzwi uye kusefa.

Furo rinonyanya kugadzirwa mumabhanzi mahombe anonzi slabstock, anotenderwa kurapa kuita chinhu chakatsiga chakasimba obva acheka nekuumbwa kuita zvidimbu zvidiki muhukuru hwakasiyana uye magadzirirwo.Iyo slabstock yekugadzira maitiro inowanzofananidzwa nechingwa chinokwira-makemikoro emvura anodirwa pabhandi rinotakura zvinhu, uye anobva atanga kupupuma furo uye osimuka mubhandi hombe (kazhinji anenge mafiti mana kureba) sezvaanofamba achidzika nemudziyo.

Iwo ekutanga mabidhi eFPF anowanzo kuwedzeredzwa nezvinowedzerwa izvo zvinopa zvinhu zvinodiwa.Izvi zvinobva pakunyaradza uye kutsigirwa kunodiwa pakugara kweupholstered kusvika kune shock-absorption inoshandiswa kuchengetedza zvinhu zvakaputirwa, kusvika kune refu-refu abrasion resistance inodiwa nekapeti cushion.

Amine catalysts uye ma surfactants anogona kusiyanisa saizi yemasero anogadzirwa panguva yekuita kwe polyols uye isocyanates, uye nekudaro kusiyanisa furo zvinhu.Zviwedzerwa zvinogonawo kusanganisira zvinodzoreredza murazvo zvekushandisa mundege nemotokari uye anti-microbials kuvharidzira mold mune zvekunze uye zvemugungwa application.
