Injection bottle rubber stopper aluminum cap

Europe and the United States are accustomed to using bromobutyl rubber to make medicinal bottle stoppers. In the early days of Asia, most of them were chlorinated butyl rubber. So far, more than 90% of medicinal butyl rubber stoppers in Japan and Taiwan are still processed using chlorinated butyl rubber. . Nowadays, the international community prefers chlorination. Because bromine is more active than chlorine, the stability and safety of chlorinated rubber stoppers are relatively high. In the past, most freeze-dried varieties used bromobutyl rubber stoppers, which were sterilized at 121 degrees. There was no problem. If the temperature is higher, you should consult the rubber stopper manufacturer. However, when brominated rubber stoppers are used, the clarity of the product is likely to be poor after it is reconstituted after acceleration or placement. Pay attention to this impact. Chlorinated rubber stoppers have better product re-dissolution clarity and have not yet been found to affect product quality.
