Why Are the Best Medical Grade Silicones Platinum-Cured?
SSP’s medical grade silicones are platinum cured for purity and comply with USP Class VI, FDA, and RoHS requirements. Specialty Silicone Products (SSP) supplies medical grade platinum-cured silicones in durometers ranging from 10 to 80 (Shore A). These ultra-clean, high-purity silicones are part of the SSP2390 series and meet stringent FDA CFR 177.2600, USP Class VI*, and […]
FDA Silicone
FDA‑compliant silicone is a high‑purity elastomer formulated to meet the material safety requirements of 21 CFR 177.2600, the U.S. Food & Drug Administration regulation governing rubber articles intended for repeated food contact. These materials are used in food processing equipment, beverage systems, dairy operations, pharmaceutical manufacturing, and hygienic sealing applications where cleanliness, durability, and regulatory […]
Is an EMC Gasket an EMI Gasket?
EMI Gasket Illustration 1 This image shows an EMC gasket used in a complete system with EMI, ESD, and environmental concerns. Its function is to help meet full EMC compliance (limits emissions and resists external EMI, plus sealing against dust/moisture). EMC Gasket Illustration 2 This image shows an EMC gasket used in a complete system […]
MIL-DTL-83528/4 EMI Connector Gaskets
EMI connector gaskets provide environmental sealing and shielding against electromagnetic interference (EMI) in electrical and electronic connectors. They are cut or molded from electrically-conductive elastomers and designed to fill small gaps between uneven connector surfaces. EMI silicones for connector gaskets are soft enough to support compression and can provide proven levels of EMI shielding while […]
Conductive Gaskets and EMI Shielding
Conductive gaskets can provide electrical and/or thermal conductivity. Electrical conductivity is a measure of the amount of electrical current that a gasket material can carry. The unit of measure is Siemens per meter (S/m). Thermal conductivityis a measure of the amount of thermal energy (i.e., heat) that a gasket material can carry. The unit of […]
Electric Vehicle EMI Shielding for EV Cars
SSP makes electric vehicle EMI shielding for cars, e-bikes, and other forms of transportation.  The EV industry needs EMI gaskets that combine proven environmental resistance with reliable shielding against electromagnetic interference (EMI) and radio frequency interference (RFI). Electric vehicle (EV) manufacturers and gasket fabricators have a choice of materials, but EMI/RFI elastomers from Specialty Silicone […]
