Conductive Silicone per MIL-DTL-83528 ( series 800 )

            Frequently your applications may require extremely high shielding effectiveness, environmental sealing, reliability, and durability. SAS’s conductive silicone elastomer family can fill these needs. These elastomers are a unique composite of high quality silicone and conductive microscopic particles manufactured to strict formulations, yielding gasketing materials that meet nearly every military and/or electronic requirement.
            SAS produces a wide variety these of conductive elastomers to choose from. This enables you, the user, to select the best suited compound for your application; keeping in mind not only performance characteristics, but economics as well. If you fail to find the perfect compound to fit your needs, within our current listing, we will create a custom compound tailored to your required specifications.
            The following part number creation system was devised to segregate the various types of conductive silicones available at SAS. The products beginning with 8xx- depict the use of microscopic particles to establish a conductive path within the silicone, yielding a highly versatile group of gasketing materials for use in EMI / RFI suppression. Each compounds has its own unique properties, therefore it is essential that a distinction be made.

The second digit in the 800 series specifies the type of silicone to be used:

80x

Standard Silicone

81x

Fluorosilicone


The third digit classifies the conductive filler type used in the compound. The different classes are as follows:

8x0

Gold Plated Nickel

8x1

Carbon

8x2

Nickel

8x3

Silver Plated Glass

8x4

Silver Plated Nickel

8x5

Silver Plated Aluminum

8x6

Silver Plated Copper

8x7

Sheet Size

The following represents available sheet sizes and thicknesses:

Available Sheet Sizes (in inches):

10" x 10", 12" x 12", 10" x 20", 12" x 18", 15" x 20"

Available Thickness (in inches):

.020", .027", .030", .032", .040", .047", .060", .062", .093", .125"

To request adhesive please add –A1 for Adhesive on 1 side and –A2 for adhesive on both sides.

Some examples of complete part numbers are:

815-1520-032 – This indicates a Silver Plated Aluminum filled Fluorosilicone sheet that is .032” thick measuring 15” x 20” without any adhesive.

815-1520-032-A1 – This represents a Silver Plated Aluminum filled Fluorosilicone sheet that is .032” thick measuring 15” x 20” with adhesive on 1 side.

803-1020-125 – This would represent a Silver Plated Glass Filled Silicone sheet that is .125” thick measuring 10” x 20”.
