1. Likopo:

The 1,2,4,5-cyclohexanetetracarboxylic dianhydride e fumana lits'ebetso tse pharaletseng ha ho etsoa li-polymer le li-resin tse sa keneleng mocheso.E fana ka botsitso bo botle ba mocheso, mocheso o phahameng oa phetoho ea likhalase, le thepa e ikhethang ea mochini, e e etsa khetho e nepahetseng bakeng sa lipolasetiki tsa boenjiniere, likoahelo, likhomaretsi le likhomphutha.Bokhoni ba eona ba ho mamella maemo a feteletseng, joalo ka mocheso o phahameng le lik'hemik'hale tse matla, bo thusa liindasteri tse fapaneng tse kenyeletsang likoloi, sebaka sa sefofane, lisebelisoa tsa elektroniki le tsa kaho.

2. Melemo:

Ka lebaka la sebopeho le thepa ea eona e ikhethang, CHTCDA e fana ka melemo e mengata e hlokomelehang.Ntlha ea pele, e fana ka khanyetso e phahameng ea mocheso le ho fokotseha ha lelakabe ho thepa, ho matlafatsa tšireletso le ho tšoarella ha lihlahisoa tsa ho qetela.Ntlha ea bobeli, botsitso ba eona bo ikhethang ba mocheso bo tiisa hore li-polymers le li-resin tsa ho qetela li lula li sa amehe ke mocheso o feteletseng o fumanoang nakong ea ho sebetsa le ho sebelisoa.Ho feta moo, k'hemik'hale ena e bonts'a thepa e ntle ea ho kenya motlakase, e etsang hore e tšoanele likarolo tsa elektroniki le tsa motlakase.

3. Litlhaloso:

The 1,2,4,5-cyclohexanetetracarboxylic dianhydride e fumaneha ka mokhoa oa granular, ka boemo ba bohloeki ba 99% kapa ho feta.E na le boima ba molek'hule ea 218.13 g/mol le ntlha e qhibilihang e ka bang 315.°C. K'hemik'hale ena e tsitsitse tlas'a maemo a tloaelehileng a polokelo 'me e lokela ho bolokoa sebakeng se pholileng, se omileng ho boloka botšepehi ba eona.

Qetellong, 1,2,4,5-cyclohexanetetracarboxylic dianhydride ke motsoako oa lik'hemik'hale oa bohlokoa haholo o sebelisoang haholo ho hlahisa li-polymers le li-resin tse sebetsang hantle.Thepa ea eona e ikhethang, e kenyelletsang ho hanyetsa mocheso, botsitso ba mocheso, le ho kenya motlakase, e etsa hore e be motsoako oa bohlokoa bakeng sa liindasteri tse fapaneng.Re u tiisetsa boleng ba boleng bo holimo, bohloeki, le ts'epahalo sehlopheng se seng le se seng sa CHTCDA seo u se fumanang ho rona.
