Silicone Compression Set: What It Means for Gaskets and Seals

Compression set measures how well silicone rubber recovers after prolonged compression. In gasket and seal applications, excessive compression set leads to leakage and loss of sealing force. This guide explains silicone compression set, how temperature affects it, and how to select the right material for reliable long-term sealing performance.
