Tšebeliso
Dioctyl terephthalate (DOTP) ke plasticizer e ka sehloohong e nang le ts'ebetso e ntle haholo bakeng sa polasetiki ea polyvinyl chloride (PVC). Ha e bapisoa le diisooctyl phthalate (DOP) e sebelisoang haholo, e na le melemo ea ho hanyetsa mocheso, ho hanyetsa serame, ho thatafalloa ke ho fetoha ha mocheso, ho thibela ho ntšoa ha metsi, bonolo le thepa e ntle ea ho thibela motlakase. E bontša ho tšoarella ho hoholo, ho hanyetsa metsi ka sesepa le bonolo ba mocheso o tlase lihlahisoa. Ka lebaka la ho feto-fetoha ha eona ho tlase, ts'ebeliso ea DOTP e ka fihlela ka botlalo litlhoko tsa maemo a ho hanyetsa mocheso tsa lithapo le likhoele, 'me e ka sebelisoa haholo thepa ea cable e hanelang ho fihlela ho 70° C (tekanyetso ea IEC ea Khomishene ea Machaba ea Botekgeniki ba Motlakase) le lihlahisoa tse ling tse bonolo tsa PVC.
Ntle le palo e kholo ea li-plasticizer bakeng sa thepa ea cable le PVC, DOTP e ka boela ea sebelisoa tlhahisong ea lifilimi tsa letlalo la maiketsetso. Ho phaella moo, DOTP e na le ho qhibiliha ho babatsehang ha mekhahlelo 'me e ka boela ea sebelisoa e le li-plasticizer bakeng sa li-derivatives tsa acrylonitrile, polyethylene, alcohol butyraldehyde, rabara ea nitrile, nitrocellulose, jj. E ka boela ea sebelisoa e le li-plasticizer bakeng sa rabara ea maiketsetso, li-additives tsa ho koahela, li-lubricant tsa lisebelisoa tse nepahetseng, li-additives tsa lubricant le li-softeners bakeng sa pampiri.
