Kusintha kwakuthupi kwa PBT kumatha kupititsa patsogolo ndikuwongolera mawonekedwe azinthuzo ndikuwongolera zomwe zimalepheretsa moto.Njira zazikulu zosinthira ndi: kusinthidwa kwa fiber, kusintha koletsa moto, mtundu wa aloyi (mwachitsanzo, PBT/PC alloy, PBT/PET alloy, etc.).

Padziko lonse lapansi, pafupifupi 70% ya ma resin a PBT amagwiritsidwa ntchito kupanga PBT yosinthidwa ndipo 16% amagwiritsidwa ntchito popanga ma PBT alloys, omwe amagwiritsidwa ntchito kwambiri m'mafakitale amagalimoto, zamagetsi ndi zamagetsi ndi zamakina.14% ina ya ma resin a PBT osalimbitsa nthawi zambiri amatulutsidwa m'ma monofilaments a nsalu zosefera ndi zosefera zamakina amapepala, matepi oyikapo, machubu achitetezo a zingwe za fiber optic ndi makanema wandiweyani aziwiya zotenthedwa ndi mathireyi.

Zosintha zapakhomo za zinthu za PBT zimayang'ana kwambiri kulimbitsa magalasi komanso kuletsa moto, makamaka PBT yomwe imagwiritsidwa ntchito ngati utomoni wapamwamba kwambiri wama fiber opangira chingwe chophimba zinthu ndi okhwima, koma pankhani ya kukana kwa arc, tsamba lotsika, kutsika kwamadzi, kuthamanga kwambiri. mphamvu, kukhazikika kwapamwamba kwambiri, modulus yopindika kwambiri, ndi zina zotero ziyenera kulimbikitsidwa.

M'tsogolomu, opanga zoweta akuyenera kukulitsa kutsika kwamadzi kuti apange ma PBT ndi PBT alloys osinthidwa, ndikulimbikitsa luso lawo la kafukufuku ndi chitukuko pakupanga kophatikizana, kusanthula kachitidwe ka CAD ndi kusanthula kwa nkhungu zamagulu a PBT.
