EMI shielding

The bi-material seal consists of an elastomer side filled with conductive particles and a silicone or fluorosilicone side. Its purpose is to isolate the conductive part of the corrosive environment (humidity, salt fog). It can also be manufactured in different grades of hardness as required. It can be co-extruded or moulded.
In contrast to an extruded gasket, a shaped seal can be installed very quickly.
In order to expand the field of use of these gaskets, STACEM has developed a moulding combination, of a filled silicone to an EPDM (resistance to Skydrol) or a fluorocarbon (resistant to NRBC).
The manufacturing method that has been developed offers a high chemical bond between the two materials.
Several grades of elastomers are possible, enabling the use in many applications (aircraft, military, nuclear, medical, food, chemical, ...).
