By comparing the oxygen index and vertical combustion grade, it can be seen that the flame retardant effect of magnesium hydroxide is significantly better than that of aluminum hydroxide, this is due to the thermal decomposition temperature of magnesium hydroxide is higher than that of aluminum hydroxide by 140 ℃, which avoids dehydration reaction occurring in advance due to the high temperature of the processing process, moreover magnesium hydroxide will form a layer of oxidized film A bɛ kɛ nɛgɛdaga sanfɛla la farikolojidɛsɛ kɔfɛ ani ka charbon dilan, o min bɛna kɛ bɔgɔlan gɛlɛn dɔ ye nɛgɛmafɛn sanfɛla la ka fara o kan, farikolojidɛsɛ kɔfɛ, idɔrɔkisidi magnɛsimu bɛna kɛ filimu oksidan ye min bɛ kɛ ka a kɛ fɛn ye min bɛ kɛ ni lastikuw ye, ka sɔrɔ ka oksizɛni gɛlɛn sɔrɔ, o cogo la, a bɛ kɛ ka ɲɛ ka ɲɛ, o cogo la, a bɛ se ka kɛ fɛn ye min bɛ se ka kɛ fɛn ye min bɛ se ka kɛ fɛn ye min bɛ se ka kɛ fɛn ye min bɛ se ka kɛ fɛn ye. Comparison of volume resistivity can be concluded, aluminum hydroxide on the EPDM insulation rubber Ethylene propylene rubber (EPR), including binary ethylene propylene rubber and ternary ethylene propylene rubber (EPDM) two categories, is a saturated rubber, with excellent electrical insulation, moisture, heat, cold and aging resistance, is widely used in the preparation of wires and cables, and has been a comprehensive alternative to the main farikolo min bɛ stirini-butadiyɛni lastikuw la i n’a fɔ kabali insulation material.
