    It is mainly used in butyl bromide rubber stopper and halogenated butyl rubber stopper. Major function is vulcanization accelerator and acid-acceptor.

The requirements for magnesium oxide: Under normal circumstances, both the light magnesium oxide and reactive magnesium oxide can be used.

It has strict requirements for light magnesium oxide’s calcium oxide, apparent specific volume, fineness and screenings. The insoluble matter in hydrochloric acid should up to standard of national standard premium grade.

The requirements for reactive magnesium oxide: iodine absorption value is more than 120. Other indexes are the same as the above.

As a general rule, for Chinese magnesium oxide, the better whiteness, the higher purite. Relatively speaking, the impurity is less.

In the aspect of index, Hebei Meishen Technology Co., Ltd is one of the drafter of magnesium oxide national standard, and a professional magnesium oxide manufacturer. The magnesium oxide quality is worth to trust and can meet the requirements from various customers.

Matters need attention: it has very strict requirements for fineness, mechanical impurities, black and white point. The clarity is mainly affected by insoluble matter in hydrochloric acid and purity. At the same time, it is affected by iron, chloride, sulfate and other impurities.
