DOTP

Plasticizer ea DOTP ke mofuta o mong oa li-plasticizers, sehlahisoa sena ke mokelikeli o batlang o se na 'mala o tlase oa viscosity. Viscosity 63mPa.s (25°C), 5mPa.s (100°C), 410mPa.s (0°C). Sebaka sa leqhoa -48°C. Sebaka se belang ke 383°C (0.1)MPa.s (0°C). Sebaka sa ho hotetsa ke 399°C. Lebitso la mahlale: dioctyl terephthalate. Ka tloaelo, re ne re e bitsa DOTP.

Ntle le palo e kholo ea li-plasticizers tse sebelisoang ka thepa ea cable le PVC, DOTP e ka boela ea sebelisoa ho hlahisa lifilimi tsa maiketsetso tsa letlalo. Ntle le moo, e na le tšebelisano e ntle haholo 'me e ka sebelisoa hape e le polasetiki bakeng sa lihlahisoa tsa acrylonitrile, polyvinyl butyral, rabara ea nitrile, nitrocellulose, joalo-joalo.
