Model：

The HI series thermal insulation silicone foam materials from Guangmai have all the excellent properties of silicone rubber at ambient temperature: excellent resilience, low thermal conductivity, good weather resistance, and long-term stability. What's more, even at temperatures as high as 500°C, the HI series thermal insulation silicone foam materials can maintain good rubber state, ensuring the material's consistency at high temperatures, and the thermal conductivity remains almost unchanged, making it have excellent thermal insulation performance.
