In order to guarantee the health of medicine and food, we need to produce according to the government standard strictly. However, for some products, some people may not know what is the criterion of acceptability, for example, the magnesium oxide for medicinal rubber stopper. This kind of product can be used in a lot of fields, therefore, they need to produce it according to the government standard of magnesium oxide for medical rubber stopper.
All the magnesium oxide manufacturers and suppliers should know that the executive standard of magnesium oxide for medical rubber stopper is HG/T3928-2007HG/T2573-2006. In the medical rubber stoppers, the magnesium oxide mainly used in butyl bromide rubber stopper and halogenated butyl rubber stopper. The main functions are vulcanization accelerator and acid-acceptor. Under normal circumstances, the light magnesium oxide and reactive magnesium oxide can be used. The requirements of light magnesium oxide: magnesium oxide is equal or greater than 93% to 95%, calcium oxide is less than or equal to 1.5%, the specific volume is equal or greater than 5 milliliter per gram, fineness should be 325 mesh, screenings is less than or equal to 0.01, and the insoluble matter in hydrochloric acid achieves premium grade of national standard.
There are some requirements which should be known by all magnesium oxide suppliers and manufacturers, and purchasers. The requirements of magnesium oxide for medical rubber stopper: iodine absorption value should be more than 120, other indexes are the same as the above. Generally speaking, for the domestic magnesium oxide, the better whiteness, the higher purity. Relatively speaking, the impurity is less. It has strict requirement for fineness, mechanical impurities and black and white point. In general, the black and white point should not exceed five points in each ten grams. The clarity mainly relates to insoluble matter in hydrochloric acid and purity. At the same time, it also relates to iron, chloride, sulfate and other impurities.
The magnesium oxide for medical rubber stopper produced by Meishen Technology takes soluble salt and ammonium bicarbonate as raw materials, and adopts advanced computer automated process. What’s more, it has complete raw material and semi-finished product detection means. The magnesium oxide quality is stable and the usability is better. Because different industries have different requirements for magnesium oxide indexes, it need professional customization and matching. Therefore, the magnesium oxide prices are also different. All the price just for reference, for the detail, you can contact with customer service to require magnesium oxide prices for different industries.
