Glass Bottle Butyl Rubber Stopper
If you think that rubber plugs are just tiny parts that we can use for simple sealing – you are wrong. Rubber stoppers can actually be much more – especially if they are used in industries such as medicine, pharmacy, and sometimes even in the chemical and food industries. Today, rubber stoppers are no longer made of ordinary rubber – but materials that are representing a combination of rubber and other polymers. Why use other polymers? Because they will further strengthen the rubber and make its properties even better.
So, what are those other materials that we use for this purpose? One such material is butyl rubber. Products made of butyl rubber are often seen in the chemical, food, and pharmaceutical industries – as well as in medicine. As a rule, bottles containing infusions, medications, medical solutions, and the like – have a butyl rubber stopper. This type of rubber stopper is most often used on glass packaging for infusions or medical solutions. There is a very good reason for such a thing. Namely, the glass bottle butyl rubber stopper is primarily reliable due to its properties such as chemical stability – but also its impermeability and resistance to high levels of heat.
A glass bottle butyl rubber stopper provides, above all, impermeability as well as good biological and chemical compatibility with other substances contained in bottles – such as drugs and infusions. That way, it will not cause any biological or chemical reactions that could affect the content or efficacy of the drugs inside the infusion or medication bottle. For special production needs, especially in the pharmaceutical industry – there is an additional safety method. Then, during production, the glass bottle butyl rubber stopper is coated with a layer of inert soft coating – that will prevent the content of the bottle from penetrating the rubber stopper. That way, a glass bottle butyl rubber stopper will ensure the long-term stability of the infusion liquid or drug in the bottle.
