Butyl rubber stopper

Butyl rubber stopper

Our butyl rubber stopper is a product that exhibits high durability, despite butyl being a material not known for strength. Our butyl rubber stoppers are a best-selling item when needing to plug holes. The best use case for our product is for sopping gasses and steam. Naturally, there are many industries out there that require a stopper impermeable to gasses and steam. We pride ourselves as the best when it comes to producing butyl rubber stoppers. The poor mechanical properties of butyl rubber make it a poor choice for our stoppers to be used in the traditional sense. Thus, our products are most commonly used in packing. With our product, you will stop oxidation by preventing air from getting into the container. This is quite possibly the best use case of our butyl rubber stoppers. But with all that said, our stoppers can be used across many industries. 

Airtightness and good heat resistance are big strengths of butyl rubber. But not only that, this material has high acid and alkali resistance. What this tells us is that butyl rubber stoppers do have a particular use case. Our products are made using the finest of materials to make sure these properties last. With our product, you can rest assured knowing that the container will be kept clean, air-tight, and functional for your needs. Our butyl rubber stopper comes in many sizes. Depending on your needs, we can find a stopper that fits the diameter requirements. Since rubber is quite a flexible material, producing butyl rubber stoppers in different sizes provides our customers with options. From 5 mm diameter to 20mm diameter, we have all kinds of butyl rubber stoppers. 

If you have any questions on the matter, feel free to contact us. We are more than eager to answer any question and help you pick the right size of rubber stopper.
