Fim ɗin PBT ɗaya ne daga cikin finafinan polyester na thermoplastic, wato fim ɗin butylene terephthalate. Density ne 1.31-1.34g/cm ³, The narkewa batu ne 225 ~ 228 ℃, da gilashin miƙa mulki zafin jiki ne 22 ~ 25 ℃. Fim ɗin PBT yana da kyawawan kaddarorin idan aka kwatanta da fim ɗin PET. PBT yana da kyakkyawan juriya na zafi, juriya mai, ƙanshin ƙanshi, da kaddarorin rufe zafi, yana sa ya dace da buhunan marufi da ake amfani da su wajen samar da abinci na microwave. Fim ɗin PBT yana da kyawawan kaddarorin shinge kuma ana iya amfani dashi don shirya abinci mai ɗanɗano. Fim ɗin PBT yana da kyakkyawan juriya na sinadarai.
(4) Fim ɗin TPX
An kafa fim ɗin TPX ta hanyar copolymerization na 4-methylpentene-1 tare da ƙaramin adadin 2-olefin (3% ~ 5%), kuma shine mafi ƙarancin filastik tare da takamaiman nauyi na 0.83g/cm ³ kawai m. Bugu da ƙari, TPX yana da kyakkyawan juriya na zafi kuma shine mafi yawan zafin jiki a tsakanin polyolefins. Yana yana da wani crystallization narkewa batu na 235 ℃, mai kyau inji Properties, high tensile modulus da low elongation, karfi sinadaran juriya, mai juriya, high jure acid, alkali, da ruwa, da kuma juriya ga mafi hydrocarbons. Yana iya jure yanayin zafi har zuwa 60 ℃, ya zarce duk sauran robobi masu gaskiya. Yana da babban nuna gaskiya da watsawa na 98%. Siffar sa a fili take, kayan ado, kuma tana da karfin shigar microwave.
Idan kuna da wasu buƙatun buƙatun jaka, zaku iya tuntuɓar mu. A matsayin mai ƙera marufi mai sassauƙa sama da shekaru 20, za mu samar da mafita na marufi daidai gwargwadon buƙatun samfuran ku da kasafin kuɗi.
