Tube-shaped Cellular Glass

1. Product Introduction

Tube-shaped 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.

3. Product Application

It is mainly used for tank bottom support and thermal insulation, pipe support and thermal insulation where high fire-proof property is required.

4. Packing & 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.

5. Application and Considerations

(1) Cellular Glass is fragile, shall be handled gently, avoid rolling or collision.

(2) Cut it with saw during application.

(3) For tank bottom application, leveling the base with fine dry sand.
