1. Nnukwu iguzogide ịka nká
Nguzogide ozone magburu onwe ya - EPDM ka amara dị ka "roba na-adịghị agbawa", ma nwee nguzogide ozone kacha mma n'etiti rubbers izugbe.
B Nkwụsi ike okpomọkụ ka mma.
C magburu onwe ya ịka nká - enwere ike iji ogologo oge na 130 ℃, enwere ike iji ya mee ihe n'oge ma ọ bụ obere oge na 150 ℃ ma ọ bụ elu okpomọkụ.
D Nguzogide ihu igwe dị mma - na-ezo aka na ịka nká nke ihe jikọtara ọkụ, okpomọkụ, oyi, ifufe, mmiri ozuzo, ozone na oxygen na gburugburu ebe obibi.
2.
