Blue Butyl Rubber Stopper
Products made of rubber and other materials with which rubber can be “strengthened” are widely used today. You can find them almost in any sphere – from the car industry to medicine and the pharmaceutical industry. Still, it is the medicine and pharmacy where butyl rubber has found its widest application. Butyl rubber stoppers are widely used as corks, caps for infusion bottles or test tubes, etc. Their high quality allows them to be used safely within the medicine and the pharmaceutical industry. And what exactly are the features of butyl rubber stoppers?
Today, butyl rubber stoppers are very often used in pharmacy and medicine. According to needs, they are produced in various sizes and colors, such as red, gray, or blue. Every size and every color has its purpose. Dimensions can also vary. So, for example, we know that a blue butyl rubber stopper is usually made in a thickness of 20mm – although this may not always be the rule. Still, the dimensions depend on the customers ordering. A product such as a blue butyl rubber stopper is primarily impermeable, which is of great importance for the pharmaceutical industry. Blue butyl rubber stopper is extremely resistant to high temperatures. Also, such stoppers are made with a special technology that allows them chemical stability in contact with both acidic and alkaline contents in the bottle.
Due to its characteristics, blue butyl rubber stopper has proven to be far better in practice than, say, plugs made of natural rubber. Namely, when we take into consideration the specificity of products such as drugs or infusions, salines, or similar – we must point out that blue butyl rubber stoppers far surpassed ordinary rubber stoppers both in function and in practical application and quality. Blue butyl rubber stopper is characterized by temperature resistance, biological and chemical stability – as well as strictly controlled production conditions and the quality of the product itself.
