IOTA-HT-820 High Hardness Silicone Foam sets a new standard for outdoor equipment protection with its exceptional mechanical strength and sealing performance. As a high-density silicone foam solution, it delivers superior durability and sealing capability, specifically engineered for outdoor communication cabinets, electronic devices, and lighting enclosures. It effectively blocks dust particles, rain intrusion, and enhances fire safety with inherent flame-retardant properties. Compared to low-density foams, it offers significantly higher tear and tensile strength, ensuring resistance to breakage under long-term high-stress conditions and extending equipment lifespan.

Key Features for Reliable Performance: The material exhibits excellent elasticity and low stress relaxation, maintaining stable compression deformation over time to minimize maintenance costs from gasket failure. Its UV resistance, ozone resistance, and wide temperature tolerance ensure consistent performance in harsh climates, including intense sunlight, high humidity, and extreme temperature fluctuations. The compact closed-cell structure further enhances sealing efficiency, providing IP-grade dust/moisture protection and airtightness for lighting, HVAC systems, and electrical control cabinets—ideal for applications requiring durable, high-closure-force gaskets.

Flexible Application & Easy Installation: Available in multiple thicknesses , it can be custom-cut to size for diverse sealing and cushioning needs. Single or double-sided pressure-sensitive adhesive options enable quick bonding to metal, plastic, and other substrates, streamlining installation and boosting productivity.

From base station antennas to industrial control panels, IOTA-HT-820 combines "high strength + long-term sealing" to deliver a robust protective barrier for outdoor equipment, helping clients reduce maintenance costs and enhance product durability.
