Hl series (generation ll) heat-insulating silicone foam material. lt owns all the characteristics of silicone rubber atroom temperature, such as excellent resilience, low thermal conductivity, good weather resistance, and stability forlong-term operation. At a high temperature of 500 'c, the product can still maintain rubber state, the thermalconductivity is almost unchanged, and it still has good resilience to ensure good thermal insulation effect. Hl-520can be compounded with substrates for integrated production, making it an ideal selection as fire-retardant andflame-retardant foams in rail transportation, industrial enyironments, and electronic equipment.
Stable performance can still be maintained in extreme environments, with extremely high weather resistance and durability
UL94 V-0 flame retardant, the smoke after combustion meets strict requirements for smoke, fire, and toxicity
From room temperature to 500 ℃, its thermal conductivity remains around 0.08 W/(m · K)
Maintaining good rubber state and resilience at temperatures as high as 500 ℃
