Ukuguqulwa komzimba kwe-PBT kungathuthukisa futhi kuthuthukise izakhiwo zemishini yento futhi kuthuthukise izici ezivimbela ilangabi.Izindlela eziyinhloko zokuguqulwa yilezi: ukuguqulwa okuqiniswe kwefayibha, ukuguqulwa kwe-flame retardant, uhlobo lwe-alloy (isb. i-PBT/PC ingxubevange, i-PBT/PET ingxubevange, njll.).

Emhlabeni jikelele, cishe amaphesenti angu-70 ezinhlayiya ze-PBT asetshenziselwa ukukhiqiza i-PBT eguquliwe futhi i-16% isetshenziselwa ukukhiqiza ama-alloys e-PBT, asetshenziswa kakhulu ezimbonini zezimoto, zikagesi kanye neze-electronic kanye nemishini.Omunye u-14% wezinsalela ze-PBT ezingaqinisiwe ngokuvamile zikhishwa zibe yi-monofilaments yezindwangu zokuhlunga nezisefo zemishini yamaphepha, amateyipu okupakisha, amashubhu esikhumulo sezintambo ze-fiber optic namafilimu awugqinsi eziqukathi namathreyi afakwe thermoformed.

Ukuguqulwa kwasekhaya kwemikhiqizo ye-PBT kugxile kakhulu ekuqiniseni i-fiber yengilazi kanye ne-flame retardant, ikakhulukazi i-PBT esetshenziswa njenge-resin ephezulu ye-viscosity ye-optical fibre cable sheath impahla yokumboza ivuthiwe, kodwa mayelana nokumelana kwe-arc, i-warpage ephansi, uketshezi oluphezulu, umthelela ophezulu. amandla, ukuqina kwe-dimensional ephezulu, i-modulus egobayo ephezulu, njll. idinga ukuqiniswa.

Ngokuzayo, abakhiqizi basekhaya kufanele bakhuthalele ukunweba ezansi nomfula ukuze bathuthukise ama-alloys e-PBT ashintshiwe kanye ne-PBT, futhi baqinise amakhono abo okucwaninga nokuthuthukiswa enqubweni yokubumba eyinhlanganisela, ukuhlaziywa kwesakhiwo se-CAD nokuhlaziywa kokugeleza kwesikhunta kwezinhlanganisela ze-PBT.
