High Temperature Resistant EMI Gasket
This series is a HF shielding gasket with high shielding performance and extremely low closure force. This prevents deflection of doors/parts, which improves shielding effectiveness. It is very effective in combination with stainless steel and metals. The core consists of a high-grade FUBA foam which is an EPDM foam covered with high conductive wear & tear resistant metallized fabric. This EMI gasket is used in large scale in automotive production up to 125 °C.
FUBA foam general description
FUBA foam is a semi-closed cell EPDM foam with excellent sealing properties. The semi-closed cell structure combines the flexibility of open cell types with the excellent sealing capabilities of closed cell types (after compression). This unique foam can be laminated with advanced adhesive technology to seal (complex) gaps against water, wind, dust, noise and heat.
FUBA foam characteristics
Good resistance to UV, humidity, high and low temperatures and chemicals (such as acids and alkalis). The flexibility of the foam makes sure that the optimal sealing performance is obtained, even with expansion or contraction of the structure caused by temperature changes. Thanks to the low compression load the foam will never deform the structure after application.
Combined with advanced adhesive technology, the foam can be applied on greasy, rough, smooth, and low energy surfaces. No heavy metals (such as cadmium) or regulated substances (such as CFC’s and halogen gases) are used during the manufacturing process nor in the product itself. FUBA foam can be disposed of by incineration.
FUBA foam gaskets are specifially designed to seal (complex) gaps against electrical noise and heat. Depending on the applications, the EMI gasket needs to be compressed between 50-80% to activate its sealing properties. Automotive – sealing of HVAC unit, dashboard, air duct, glass run, fire wall. Building and construction – sealing of exterior panel joints, solar panels. Industrial – sealing of air-conditioners, mobile phones, refrigerators.
