Silicone-Loaded EMI / RFI Shielding
Through our Ronsil silicone rubber division, Reiss Manfacturing offers silicone-loaded EMI / RFI shielding, suppression, and absorption reduction product..
We formulate silicone rubber loaded with various types of metals and determine the loading percentage based on the shielding or suppression requirements. Some suppression materials that are avaliable are carbon black, silver coated sub-straights, graphite, and more.
We offer custom:
- Electrically conductive elastomers
- Shielding elastomers
- Suppression elastomers
- Absorption elastomers
Two main applications for microwave absorbing materials are EMI (electromagnetic
interference) and RCS (radar cross sections) reduction in military and
commercial electronics, such as high-frequency consumer electronics, notebook
computers, wireless LAN devices, network servers and switches, wireless
antenna systems and more.
Military: Surface ships
Today's military vessels are very complicated and utilize high-tech equipment in their electronics systems. Problems occur due to space constraints where many times a signal or harmonics from one piece of equipment will interfere with other electronic equipment.
This problem has become increasingly challenging with the powerful broadband
jamming equipment being used. Constructing absorber barriers can help
with this issue.
Automotive:
Microwave-absorbing elastomer can be used inside microwave housings such
as back-up or crash avoidance devices.
Commercial:
High-frequency wireless devices often have powerful transmitters and sensitive receivers in close proximity. Silicone elastomer absorbers are custom formulated and manufactured into a sheet and laminated with PSA (pressure sensitive adhesives). The material can be die cut and then placed in the housing of electronics to absorb unwanted reflections and is becoming a necessity as electronics move to higher frequency and speeds. (Material can be molded to custom shape.)
