Most unmanned aerial vehicles (UAVs) require communications with ground-based systems such as radio gateways. Electromagnetic interference (EMI) can disrupt these communications, degrade the quality of global positioning system (GPS) reception, and interfere with the drone’s onboard compass, which is calibrated according to the Earth’s magnetic field. The causes of UAV EMI are numerous, but electrically conductive gaskets made of shielding silicones are part of the solution.What [...]

Specialty Silicone Products (SSP) recently received a certificate of compliance (COC) from NAMSA, the world’s leading MedTech Contract Research Organization, for a 10-durometer silicone test article that passed USP Biological Reactivity Tests, In Vivo for USP Plastics Class VI.  This is the second material in our SSP2390 family of USP Class VI silicones to receive a NAMSA COC. The first was for a 50-durometer test article that passed this same group of tests, which are performed on [...]

Specialty Silicone Products (SSP) makes USP Class VI silicones for medical applications. The SSP2390 family of products isn’t new, but the marketplace for these materials continues to evolve. To keep up with the changes, medical device designers and manufacturers need elastomers they can trust. That’s especially important during the current supply chain crisis because silicone elastomers and their ingredients are in short supply. When you buy USP Class VI silicones from SSP, however, [...]

Specialty Silicone Products (SSP) makes conductive shielding elastomers, including five QPL listed products that meet MIL-DTL-83528 requirements. For engineers who need EMI/RFI gaskets for military applications, it’s important to know what MIL-DTL-83528 is and how it’s related to the QPL. It’s also worth learning about some other conductive shielding elastomers that are used in military projects.  What is MIL-DTL-83528?MIL-DTL-83528 is a detail specification from the U.S. [...]

Redesigning an EV battery box because of a gasket problem can be difficult and expensive. It’s better to account for EV battery box sealing up-front than to design the case and discover that a gasket won’t fit, or that a chosen material wasn’t the best selection. Along with low-temperature flexibility and high-temperature resistance, EV battery box gaskets need to provide shielding against electromagnetic interference (EMI). They also need to meet tough flammability [...]
