Elastomers are the key to providing effective sealing solutions for applications in outdoor, marine, medical and any environment where sealing stuff in or sealing stuff out is imperative. Elastomers are versatile materials typically composed of polymers, and manufacturers prize them for their ability to bend and stretch in a variety of ways before returning to their original shape.
However, not all elastomers are the same. Elastomers can incorporate a wide range of designs and materials depending on the needs of their intended application. More than 20 different types of standard elastomers exist, and each possesses unique functions in both process equipment and finished products.
Different elastomer formulations affect the physical properties, functions, and service life of your components and systems. This is why it’s essential to test a few different elastomers to determine the best one for your needs. In this post, we outline ways to evaluate elastomers for their capacity to perform well in your application, and we also describe some of the best uses of each different type of elastomer.
When you’re trying to determine the best kind of elastomer to use for your sealing or fastening application, keep the following few questions in mind:
Even though many differences exist between the types of elastomers on the market, they all bring unique advantages to injection molding processes and products. The injection molding process forces rubber compounds into a mold using high pressure. Elastomers perform well in this type of environment because they’re made of similar materials as those used in injection molding.
Compression molding is another area that benefits from the use of elastomers. The compression molding process takes high-viscosity compounds and processes them into a pre-form. It then compresses the pre-form into a mold before curing it.
Elastomers work well in a variety of hostile environments, such as:
Building quality sealing boots or fasteners involves accounting for many variables. Fortunately, we at APM Hexseal bring years of experience to the elastomer design process, helping customers across the globe find ways to get the most from their elastomer options.
