Product Description Product DescriptionHigh-density micro-foamed silicone is a high-performance material engineered for applications requiring durability, thermal stability, and chemical resistance. Made from an extremely resilient silicone, this foam sheet demonstrates excellent resistance to heat, weathering, ozone, UV radiation, and a wide range of chemicals. It is non-toxic, chemically inert, and maintains its physical properties across a broad temperature range from -60°C to 230°C.Unlike traditional foam materials, high-density silicone foams do not dry out or degrade over time, ensuring long-term reliability. These characteristics make them ideal for applications where standard foams fail-particularly in high-temperature or chemically aggressive environments. HIGH DENSITY FOAMED SILICONE - KEY FEATURES1.
