Butyl stopper

Our butyl stopper is a product that ensures an air-tight and clean container environment. The purpose of a butyl stopper is to be used with glass containers of all sizes to prevent contamination. Our butyl stopper is a product that will keep any container clean and airtight. Butyl stoppers are excellent for preventing gasses from entering a container. With use across many industries, our products will ensure a safe and clean container environment. 

Butyl is a material with mechanical properties, but excellent impermeability to gasses, chemicals, water, and air. Because of that, a butyl stopper is best used as a sealant for a glass container. Due to the air-tight nature of the material, you will have no trouble keeping containers airtight. Even if there are dozens of industries that require our products, we don’t exclusively sell to one. Any company that requires a stopper that can prevent air tightness and good heat will benefit from our product. But not only has that, but the high alkali and chemical resistance prevents the risk of potential spills. Simply said, our product does have a particular use case. Since we make our butyl stopper using the finest materials, we can vouch for the quality of the stopper. With our product, our clients should know that air won’t get in where it doesn’t need to. Also, with our stoppers, the container won’t be compromised and instead remain clean.

We make butyl stoppers in many sizes. Due to the increasingly flexible nature of rubber, forming stoppers in different diameters isn’t a difficult job. What this tells you is that we have a butyl stopper in nearly every size. From 5 mm diameter to 20mm diameter, all you need to do is figure out the right diameter size. We are more than happy to assist you with any questions you might have.
