Usage of the product

1. Cooling for LNG gas tanks and pipes
2. Construction material (keeping warm or cool)
   
   

This foam glass is manufactured using soda lime glass (Soda Lime Silicate Cellular Glass Block). It  has no absorption at all with high compressive strength. Thus, its effect is excellent at ultra low temperature and used to cool gas tanks and gas tubes.

In addition, its adiabatic feature at ultra low temperature is excellent, and it does not have heat decomposition at high temperature (about 450°C) to assure safety from noxious gas during fire. It can be applied to building materials, especially widely used in humid Southeast Asian countries.
