Silicone foam strips provide reliable sealing against dust, moisture, air, and vibration while maintaining excellent flexibility over a wide temperature range. Their low compression set and weather resistance make them suitable for long-term industrial sealing applications.
At SENMA, we manufacture custom silicone foam strips in various densities, thicknesses, and adhesive configurations to support industries including electronics, automotive, battery energy storage systems (BESS), medical devices, LED lighting, and HVAC.
Provides effective protection against dust, air leakage, moisture, and environmental contaminants.
Operates continuously from -40°C to 180°C, with custom high-temp grades available upon request.
Maintains sealing pressure and structural resilience after long-term repeated compression, extending service life.
Performs reliably in harsh outdoor environments exposed to continuous UV sunlight, ozone, humidity, and thermal aging.
