Not every gasket failure is a material problem.

Compression set, improper installation, chemical exposure, and extreme temperatures can all impact gasket performance over time. Small sealing issues can quickly turn into equipment reliability problems and costly downtime.

Stockwell Elastomerics breaks down common gasket failure modes, why they happen, and how proper material selection and gasket design can help reduce risk early in development.

EMI/RFI shielding plays a critical role in protecting electronics from unwanted electromagnetic interference — and ensuring systems meet EMC requirements.

Signal interference can impact performance, reliability, and compliance. Conductive silicone EMI gaskets help block external interference while containing internal emissions — all while providing environmental sealing against dust and moisture.

Learn how EMI/RFI shielding works, why conductive silicones matter, and how the right gasket design can improve enclosure performance.

Wondering what EMI/RFI Shielding is? Get the facts from the experts at Stockwell Elastomerics here or call for more information.
