The Thermal conductivity of silicone sponge gel ranges from 0.8–12 W/mK (customizable gradient: 1/2/3/5/8 W/mK)

Temperature resistance: -60°C to 230°C; the Sanpu formulation withstands short-term exposure up to 315°C.

 

Thermal conductivity of polyurethane foam ranges from  0.5 to 4 W/mK

Temperature resistance: -40°C to 120°C; above 120°C, the material tends to age, become sticky, and release small molecules.

 

Thermal conductivity of Thermal-conductive EVA foam usually from 0.5–3 W/mK

The range of temperature resistance of thermal-conductive EVA foam is -30°C to 80°C; When the temperature above 80°C, the material of EVA Foam will soften and deform

 

The Thermal conductivity range of Thermal-conductive EPDM rubber foam is 0.6–2.5 W/mK

Temperature tolerance of EPDM foam range from -50°C to 150°C

 

The parameters of Thermal-conductive PE/XPE foam ranges from 0.4 to 2 W/mK

Temperature tolerance of PE/XPE foam  ranges from -20°C to 75°C
