I-PBT isifinyezo sePolybutylene Terephthalate. Kuhlukaniswa ochungechungeni lwe-polyester. Ihlanganiswe nge-1.4-Burylene Glycol ne-Teerephthalic acid (TPA) noma i-Teerphthalate (DMT). Kuyi-Milky Translucent ku-Opaque, i-crystalline thermoplastic polyester resen eyenziwe ngenqubo ehlanganisiwe. Ngokubambisana nesilwane sasekhaya, kubhekwana ngokuhlangene njenge-thermoplastic polyester, noma i-polyester egcwele.
Izici zamapulasitiki we-PBT
1. Ukuguquguquka kweplasitiki ye-PBT kuhle kakhulu futhi kuyamelana kakhulu nokuwa, futhi ukumelana kwaso okugqamile kuqinile.
2. I-PBT ayisho ukuthi ivutha amapulasitiki ajwayelekile. Ngaphezu kwalokho, umsebenzi wayo wokuzichaza kanye nezindawo zikagesi ziphakeme kakhulu kulepulasitiki ye-thermoplastic, ngakho-ke intengo iyabiza kakhulu phakathi kwamapulasitiki.
I-3. Ukusebenza kokutholwa kwamanzi kwe-PBT kuphansi kakhulu. Amapulasitiki ajwayelekile akhubazwa kalula emanzini ngamazinga okushisa aphezulu. I-PBT ayinayo le nkinga. Ingasetshenziselwa isikhathi eside futhi ilondoloze ukusebenza okuhle kakhulu.
I-4. Ingaphezulu le-PBT libushelelezi kakhulu futhi ukungqubuzana kwengxabano kuncane, okwenza kube lula ukusebenzisa. Kungenxa yokuthi i-coefflent yayo yokungqubuzana incane, ngakho-ke kuvame ukusetshenziswa ngezikhathi lapho ukulahlekelwa kwengxabano kukhulu.
I-5 Ngisho nasemakhemithini esikhathi eside, kungagcina isimo saso sokuqala kahle, ngaphandle kwezinto ezithile ezinjengama-acid aqinile nezisekelo eziqinile.
I-6. Amapulasitiki amaningi aqiniswa ikhwalithi, kepha izinto ze-PBT azikho. Izakhiwo zalo zokugeleza zinhle kakhulu, futhi izakhiwo zayo zokusebenza zizoba ngcono ngemuva kokubumba. Ngoba yamukela ubuchwepheshe be-polymer fusion, yanelisa ezinye izakhiwo ze-alloy ezidinga i-polymer.
Ukusetshenziswa okuyinhloko kwe-PBT

2. Izicelo ze-elekthronikhi nezenzi zikagesi
3. Izinkambu zohlelo lokusebenza zezingxenye ze-auto: izingxenye zangaphakathi ezifana namabakaki we-wiper, ama-valves okulawula, njll; Izingxenye ze-elekthronikhi nezenzi zikagesi ezinjengezimoto ezilahla amapayipi asontekile kanye nezixhumi zikagesi ezihlobene.
