Foam glass tube/sound insulation/heat insulation pipe

Foam glass description:

Foam glass is a new inorganic insulation material with glass as the main raw material, made through adding appropriate blowing agent, heating and roasting by high temperature tunnel kiln, and at last annealing and cooling process, which has uniform independent airtight air-gap structure.It complete retains the chemical stability of inorganic glass, with properties of low volume density, low heat conductivity, anti-moisture permeability, water repellence,non-combustibility, no virulence variation, rodent proof,high mechanical strenght, easy processing, capability of resistant all chemical erosion except hydrogen fluoride.
