LTE-20 is a Shore A 65 durometer hardness silicone elastomer filled with silver plated aluminum particles as the

conductive and shielding media. This material has excellent shielding properties and conductivity and meets the

re-quirements of MIL-DTL-83528 type B. This material 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-20 provides

good corrosion resistance with aluminum and other substrates. It is recommended for applications where there

are dissimilar mating surfaces, the presence of salt fog or in uncontrolled environments. This material can be

supplied as molded parts, extruded shapes, die cut parts, or as standard sheet stock. Please contact Leader Tech for

additional information regarding your specific application.
