Kemikoro siratigɛ la, alkili poliyetɛriw bɛ kɛ fɛn fɔlɔw ye poliyuritan fomuw, nɔrɔlanw, sigilanw ani elastomɛriw la. Poliyuritani fomu bɛ kɛ kosɛbɛ minɛnw na, matiriyaliw, mobili sigilanw ani sow kɔnɔfɛnw na. Poliyuritan nɔrɔlanw ni sirilanw bɛ kɛ ka sow, mobili ani ɛntɛrinɛti minɛnw lajɛ.
Furakɛcogo la, alkili poliyetɛriw bɛ kɛ dɛmɛnanw ni fɛnɲɛnɛmafagalanw ye furaw la, o bɛ dɔ fara u sabatili n’u wulicogo kan. U bɛ kɛ fana ka tulumafɛnw, farikolojidɛsɛ furaw ani jisumafɛnw dilan, u bɛ kɛ ka caya da la, nugu la, ɲɛdimifura la, tulo la, ani shampow la.
