Thickness Tolerance, Die-Cut, and Waterjet Cut Tolerances for Sponge/Foam Gaskets
Standard Thickness and Cutting Tolerances for Sponge Rubber Gaskets When designing with sponge rubber, engineers need to account not only for material properties like density and compression but also for thickness and cut tolerances. These tolerances directly impact...
FOD Gaskets; Gaskets to Prevent FOD: Silicone Rubber, Poron®, Silicone Foam, and Silicone Sponge
In industries where reliability and cleanliness are paramount—such as aerospace, defense, electronics, and medical devices—the risk of foreign object debris (FOD) is never taken lightly. A single loose particle, shaving, or improperly selected material can jeopardize...
Compression Rates in Rubber Gaskets : Solid vs. Foam/Sponge for Air & Water Sealing
Why Compression Rate Matters When designing with gaskets, compression isn’t just about fit—it directly determines sealing performance, stress relaxation, and gasket life. Compress too little, and you get leaks; compress too much, and you risk tearing or losing...
Gaskets in Medical Devices: Silicone Rubber, Expanded PTFE, and Viton®
