Ojiji
Dioctyl terephthalate (DOTP) bụ ihe e ji plasticizer mee nke nwere arụmọrụ dị mma maka plastik polyvinyl chloride (PVC). Ma e jiri ya tụnyere diisooctyl phthalate (DOP) a na-ejikarị eme ihe, ọ nwere uru dị na iguzogide okpomọkụ, iguzogide oyi, mgbanwe siri ike, mgbochi mwepụta, ịdị nro, na ezigbo ihe mkpuchi eletriki. Ọ na-egosi ogologo oge dị mma, iguzogide mmiri ncha na obere nro okpomọkụ na ngwaahịa. N'ihi obere mgbanwe ya, ojiji nke DOTP nwere ike iru ihe achọrọ maka ọkwa iguzogide okpomọkụ nke waya na eriri, a pụkwara iji ya mee ihe nke ukwuu na ihe eriri na-eguzogide 70.° C (Ụkpụrụ IEC nke International Electrotechnical Commission) na ngwaahịa PVC ndị ọzọ dị nro.
Tinyere ọtụtụ ihe eji eme plastik maka ihe eji eme eriri na PVC, enwere ike iji DOTP mee ihe na mmepụta ihe nkiri akpụkpọ anụ arụ. Na mgbakwunye, DOTP nwere ezigbo ike ịgbaze n'oge ma enwere ike iji ya dị ka ihe eji eme plastik maka ihe ndị sitere na acrylonitrile, polyethylene, alcohol butyraldehyde, roba nitrile, nitrocellulose, wdg.
