Techsil Conductive Elastomer LTE-85 Performance of conductive elastomers vary from one application to another. Leader Tech, Inc. cannot guarantee that the above specifications will be met in your specific application. If you need assistance in testing your application, please do not hesitate to contact Leader Tech for further information. Global EMI Shielding Technology Center 12420 Race Track Rd., Tampa, Florida 33626 www.LeaderTechInc.com Copyright© Leader Tech, Inc. 2013 LTE-85 is a Shore A 75 durometer hardness ethylene propylene diene monomer (EPDM) elastomer filled with nickel coated graphite particles as the conductive and shielding media. This material has good shielding properties and conductivity and is recommended in applications exposed to NBC (Nuclear Biological Chemical) wash-downs with DS- 2 and STB. LTE-85 has good sealing properties and is also resistant to steam due to its high impermeability elastomer base. LTE-85 has a shelf life of 5-10 years if stored in the absence of moisture, light and sulfur. LTE-85 exhibits good performance in moderately corrosive environments and has high physical strength and abrasion resistance. This material can be supplied as molded parts, die cut parts, select extruded profiles, or as standard sheet stock. Please contact Leader Tech for additional information regarding your specific application.
