FOAMGLASS (Cellular glass)
DESCRIPTION:
Foam glass (Cellular glass) is a kind of inorganic non-metallic glass material, which is made of broken glass, foaming agent, modified additive and foaming promoter, after fine grinding and uniform mixing, and then through high temperature melting, foaming and annealing. It is composed of a large number of uniform bubble structures with a diameter of 1-2 mm. The sound absorption foam glass is more than 50% open cell bubbles, and the adiabatic foam glass is more than 75% of closed cell bubbles. It can be adjusted according to the requirements of the production, through the change of production technology parameters.
FEATURES:
1. Keep heat insulation performance for a long time, used for roof insulation
2. Second waterproof function
3. Fire and corrosion protection
4. Good dyeing performance
5. Good sound insulation performance
