Antioxydant ihendutse EPPD (6PPD+7PPD) cas 793-24-8, 3081-01-4

EPPD ni imvange ya N-(1,3 - Dimethylbutyl)-N'-phenyl-p-phenylenediamine na N-(1,4 - Dimethylpentyl)-N'-phenyl-p-phenylenediamine mu rugero runaka. Iki gicuruzwa ntigitanga nitroso compound muri rubber, ni ubwoko bushya bw'icyatsi kibisi cyita ku bidukikije rubber isaza. Iki gicuruzwa gifite ubudahangarwa bukomeye kuri ozone na oxidation, bityo kirwanya umunaniro mwinshi n'ubushyuhe bwinshi. Gushonga ni byiza iyo ukoresheje rubber. Guhindagurika guke kandi kugenda buhoro. Bishobora gukumira umuringa, manganese n'ibindi byuma byangiza kwangirika. Iki gicuruzwa kiba gifite amazi ku bushyuhe bw'icyumba, bityo biroroshye gutegura no gukoresha iyo gikoreshejwe nyuma yo kuvura rubber ya sintetike. Igipimo muri rusange ni 0.3 kugeza 0.5%.
