Izithethantonye
I-1,1'-dithiobis (n,n-dimethylthio-formamid; 1,1'-dithiobis(n,n-dimethylthio formamide); i-Aapirol; i-Accel TMT; i-Accelerator T; i-Accelerator Thiuram; i-accelerator; i-thiuram ye-accelerator.
Iipropati
Imveliso ecocekileyo yikristale engenambala kwaye ayinayo ivumba. Inyibilika ngokulula kwibenzene, chloroform (230g/L), iacetone (80g/L, carbon disulfide kunye nezinye izinyibilikisi eziphilayo, zinyibilika kancinane kwi-ether kunye ne-ethanol (<10g/L), enganyibilikiyo emanzini (30mg/L), ibolile ngeasidi, umbala umhlophe okanye umgubo otyheli okhanyayo.
Umsebenzi
I-TMTD ye-rubber ye-accelerator yi-accelerator yesibini ebalaseleyo yohlobo lwe-thiazole. Isenokusetyenziswa kunye nezinye ii-accelerators njenge-accelerators ye-vulcanization eqhubekayo yamasuntswana e-colloidal. Ngesiqhelo, isenokusetyenziswa ngokudityaniswa ne-accelerator MBT(M). I-vulcanization yerabha ye-butyl iyafana. I-accelerator isetyenziswa kakhulu ekwenzeni amatayara, iityhubhu zangaphakathi, izihlangu zerabha, izixhobo zonyango, iintambo, iimveliso zerabha zamashishini, njl. njl. Isetyenziswa njengeyeza lokungunda kunye nesibulali-zinambuzane kwezolimo, kwaye ingasetyenziswa njenge-lubricant additive.
