Purchasing considerations for magnesium oxide

Because many of the details in their production process is not known, so at the time of purchasing magnesium oxide, the product may be not suitable for use.
First of all, for the tire industry, the content of magnesium oxide needs between 90-95. Loss on ignition＜0.5, Water solubles＜0.5, bulk density(g/ml) is also a important index. In the conveyor industry, we need to focus on the content and indicators of magnesium oxide. General the active content between 40-60 is well. Calcium can be controlled within 1.5. This is according to most of manufacturers, not suitable for everyone. We need concrete analysis of concrete conditions, or you can inquire directly our online customer service.

In the cable industry, the content of calcium not too much, otherwise the rubber sheath of electric cables will become brittle and appear leakage current and other dangerous situations, then influence the service life of products. The content of water solubles can not to much, or blisters will appear on the cable epidermis. If the content of screenings is too much, there will appear trachoma, leakage current and other situation. Generally light magnesium oxide should be used, but the active content between 40-60 is well. In the adhesive industry, pay attention to the iron content, iron content is too easy to change color. Calcium content not to expect too much, screenings and calcium content is too high to appear stratification phenomenon. The content of active between 120-150 is well.
