The temperature ranges presented above are approximations for dry air service only and should not be used to determine design specifications or end-use temperature limits. Actual temperature range of a compound in an end-use application is highly dependent on part type, hardware configuration, applied forces, chemical media, pressure and thermal cycling effects, and other factors. The most practical way of determining an end-use temperature range is testing in the actual application conditions. Consult a Marco Engineer for more details.



Ohmerics® Compound Summarized Descriptions:

Ohmerics® S1104 : Black, 70 Durometer, Carbon in a silicone binder. This material should be used in a commercial ESD or grounding application only. When coupled between two aluminum Flanges in a salt air environment this material will create galvanic action where corrosion will occur. Do not use for outdoor military applications. Compares to Chomerics® CHO-SEAL® 6600 and CE-005 and Ja-Bar series 801.

Ohmerics® S1081 : Dark Gray, 65 Durometer, Nickel Plated Graphite in a silicone binder. This material will provide good shielding in a wide range of applications. This material should be used in Commercial applications and comes in a wide variety of shapes and sizes. Compares to Chomerics® CHO-SEAL® S6305, EcE 93 and CE-007 and Ja-Bar series 804.

Ohmerics® S1106 : Tan, 65 Durometer, Silver Plated Glass in a silicone binder. This material is to be used in commercial applications where there will be little shock and vibration present. This material can be used in such commercial applications as, servers, towers and communications equipment. Compares to Chomerics® CHO-SEAL® 1356, Ja-Bar Series 803.

Ohmerics® F1015 : Dark Gray 65 Durometer, Nickel Plated Graphite in a Fluorosilicone binder. This material will provide good shielding effectiveness `and can be used in the presence of jet fuels, fuel oils and solvents in a flight line environment. This material will stand up well in a corrosive environment and can be manufactured in many different profiles. Compares to Chomerics® CHO-SEAL® L6303, EcE 92 and Ja-Bar series 812.

Ohmerics® S1097 : Blue, 65 durometer Silver Plated Aluminum filler in a silicone binder. This compound provides high shielding effectiveness and can be used in most military or commercial application where fuels and chemical fluids are not present. This material can be used in a broad range of applications. Compares to Chomerics® CHO-SEAL® 1285, EcE 81 and CE-009 and Ja-Bar series 805.

Ohmerics® F1013 : Blue, 70 durometer Silver Plated Aluminum filler in a Fluorosilicone binder. This material provides high shielding effectiveness, but more importantly you can use this material in applications where the equipment will be in severe environments. This is very good material that will withstand being in a corrosive environment as well as being subjected to jet fuels and fuel oil type fluids. Compares to Chomerics® CHO-SEAL® 1287, EcE 89 and CE-006 and Ja-Bar series 815.

Ohmerics® S1100 : Tan, 65 Durometer, Silver Plated Copper filler in a silicone binder. This material provides very high shielding effectiveness, however this material should not be used in a tropical environment. This gasket material should be used in an application where the equipment will not be subjected to corrosive salt air. Compares to Chomerics® CHO-SEAL® 1215, EcE 80 and CE-001 and Ja-Bar series 806.

Ohmerics® F1016 :  Blue 70 Durometer, Passivated Silver Plated Aluminum in a Fluorosilicone binder. This material was developed primarily for use in military applications. This material will provide excellent shielding in a harsh environment. Can be used on shipboard and military aircraft applications. Compares to Chomerics® CHO-SEAL® 1298 and CE-016.

Ohmerics® E1077 : Black, 75 durometer Nickel Plated Graphite in a ethylene propylene diene Monomer (EPDM). This material provides good shielding effectiveness and is primarily used in military applications where Nuclear, Biological, Chemical (NBC) equipment wash downs are possible. Compares to Chomerics® CHO-SEAL® E6306 and CE-010 and Ja-Bar series 822.
