Butyl Ruber Applications: Seals and Gaskets

Learn about the properties of butyl rubbers and the applications for butyl rubber seals and gaskets.

Did you drive to work today? Maybe you took the bus instead. If your commute involved traveling on tires, then butyl rubber helped get you there. Tires are made of several different elastomers, but butyl plays a special role. Because this synthetic rubber resists the passage of gases, butyl is used for the inner liner, the part of the tire that holds the compressed air. Butyl also resists moisture, and that helps keep the steel belts that are embedded in car, truck, and bus tires from rusting. Butyl resists chemicals, too.

Cold Bonding for Custom Gaskets

Learn how to determine if cold bonding is the right joining or splicing technique for your custom gaskets.

Do you need a custom gasket that looks the corner of a picture frame? L-shaped rubber gaskets require more than just dimensional accuracy. Application requirements and cutting techniques are important to consider, but so is the splicing method. Gasket fabricators use different technologies to join cut lengths into corners, so it’s important to consider all of your available options. In most gaskets designs, the corners are more susceptible to leaks than other parts of the seal.

Cold bonding is a joining method that offers important advantages, but it’s not right for every sealing application. So how can you determine if cold-bonded gaskets are what you need? For starters, let’s define cold bonding and compare it to some “hot” splicing techniques. We’ll also consider cold bonding in terms of application requirements such as performance and cost, and examine how waterjet cutting supports this cost-effective joining method. Finally, we’ll look at gasket assembly.
