SSP supplies low durometer silicones for EMI shielding and medical, military, and aerospace gaskets. Learn more.
Specialty Silicone Products (SSP) supplies low-durometer silicones for medical, military, aerospace, and other demanding applications. These softer elastomers are available in durometers ranging from 10 to 30 (Shore A). Products include platinum-cured, medical-grade silicones; various military and aerospace silicones; and a 30-duromter EMI shielding silicone that’s filled with silver-aluminum particles.
SSP supplies these and other silicone elastomers as continuous rolls, molded sheets, and ready-to-mold compounds. Depending on your application requirements, rolls and sheets with custom thicknesses and widths are available. SSP’s softer silicones can be reinforced for additional strength, and are available in a variety of colors to support your product designs.
Low Durometer Medical Silicones
The SSP-2390 family of products includes platinum-cured silicones in 10, 20, and 30 durometer (Shore A). These translucent, heat-cured elastomers are FDA CFR 177.2600, USP Class VI, and RoHS compliant. Tensile strength, elongation, Tear B, and specific gravity vary with durometer.
Because SSP-2390 silicones are platinum-cured, these specialty elastomers have lower levels of extractables – chemical compounds that migrate under conditions such as elevated temperature or surface exposure. Compared to peroxide-cured elastomers, platinum-cured silicones also offer greater control over cure rates and crosslinking. They’re more consistent in terms of physical appearance, too.
Low Durometer Military and Aerospace Silicones
In addition to medical devices and equipment, SSP-2390 softer silicones can be used in military or aerospace applications that require high-purity compounds. Two additional products for military and aerospace applications are also available.
SSP-390 is a 25-durometer, peroxide-catalyzed, heat-cured silicone that meets the requirements of A-A-59588, Class 2A and 2B, Grade 25
SSP-1850-C-30 is a 30-durometer, thermally-conductive silicone elastomer for heat transfer applications.
Low Durometer EMI Shielding
SSP also supplies a softer, particle-filled silicone for EMI shielding. SSP-2426-30 is a 30-durometer, electrically-conductive elastomer that’s softer than many other EMI materials. Filled with silver-aluminum particles, this shielding silicone proves that metal-filled conductive silicones don’t have to be “too hard”. Plus, this ultra-soft silicone is a true 30-durometer (Shore A) product.
