Technical Data Sheet
TDS062713-LTE75
The Leading Edge in EMI Shielding Technology
Techsil Conductive Elastomer LTE-75
LTE-75 is a Shore A 45 durometer hardness silicone elastomer filled with silver particles as the conductive and
shielding media. This material has good shielding properties and conductivity and meets the requirements of MIL-
DTL-83528 type J. This material also requires a lower compressive force in order to reach the desired state of
compression. LTE-75 has excellent sealing properties at temperature extremes, is ozone resistant and has a long
shelf life if stored in the absence of moisture, light and sulfur. LTE-75 exhibits good performance in non-corrosive
environments. This material can be supplied as molded parts, die cut parts, extruded profiles, or as standard sheet
stock. Please contact Leader Tech for additional information regarding your specific application.
