product description
Cellular Glass is a rigid inorganic thermal insulating product, composed of uniform closed cells. It is made from pure glass and foaming agents, through high temperature foaming and annealing. It reserves the chemical stability of glass, and characterized by low density, low thermal conductivity, impermeability, no water absorption, incombustibility anti-mildew/rat, high mechanical strength but easy to cut. It can bear all kinds of chemical erosion except the hydrofluoric acid.

Product Application
It is mainly applied to the insulation for low temperature/cryogenic pipes, vessels, tanks and equipment. It can also be used in dual temperature system.
Packing and Storage
(1) Carton packing, special packing is available on request.
(2) During shipment, keep cartons tightly closed, keep stacks upright to protect from collision. If necessary, reinforcement can be applied.
(3) Store in weatherproofing, dry and ventilated environment, no more than 6 layers stack is preferred.
Application and Cautions
(1) Cellular Glass is fragile, shall be handled gently, avoid rolling or collision.
(2) Fix cellular glass segments by stainless steel band when applied in pipe/equipment insulation.
(3) Cut it with saw during application.
