Flexible polyurethane thovu (FPF) ndi polima opangidwa kuchokera zimene polyols ndi isocyanates, ndondomeko mankhwala upainiya mu 1937. FPF imadziwika ndi ma cellular dongosolo kuti amalola mlingo wina wa psinjika ndi kulimba kuti amapereka zotsatira cushioning.Chifukwa cha malowa, ndizinthu zomwe amakonda pamipando, zofunda, mipando yamagalimoto, zida zamasewera, zonyamula, nsapato, ndi kapeti.Imagwiranso ntchito yofunika kwambiri pakuletsa mawu komanso kusefera.

Chithovu chimapangidwa nthawi zambiri m'mabanki akuluakulu otchedwa slabstock, omwe amaloledwa kuchiritsa kukhala chinthu chokhazikika chokhazikika ndikudula ndikuchipanga kukhala tizidutswa tating'ono ting'onoting'ono ndi masinthidwe osiyanasiyana.Njira yopangira slabstock nthawi zambiri imafanizidwa ndi kukwera kwa mkate-mankhwala amadzimadzi amawathira pa lamba wonyamulira katundu, ndipo nthawi yomweyo amayamba kuchita thovu ndikukwera m’bulu lalikulu (lomwe nthawi zambiri limatalika mamita anayi) pamene akuyenda pansi pa chotengeracho.

Zopangira zoyambira za FPF nthawi zambiri zimaphatikizidwa ndi zowonjezera zomwe zimapereka zomwe mukufuna.Izi zimachokera ku chitonthozo ndi chithandizo chofunikira pa mipando yokwezeka mpaka kugwedezeka komwe kumagwiritsidwa ntchito kuteteza katundu wopakidwa, mpaka kukana kwanthawi yayitali kwa abrasion komwe kumafunidwa ndi khushoni ya carpet.

Amine catalysts ndi surfactants akhoza zosiyanasiyana kukula kwa maselo opangidwa pa zimene polyols ndi isocyanates, ndipo potero amasiyana thovu katundu.Zowonjezera zingaphatikizepo zoletsa moto kuti zigwiritsidwe ntchito mundege ndi magalimoto ndi anti-microbials kuti aletse nkhungu panja ndi m'madzi.
