Using special nanotechnology, FMA650 combines a silica aerogel with reinforcing fibers to deliver very low thermal conductivity, low density and good flexibility in an environmentally safe product. FMA650 provides excellent properties of waterproof, sound absorption and shock absorption. FMA650 is an alternative to the common, environment unfriendly, inferior insulation products, such as PU, asbestos insulation felt, silicate fibers, etc.
