Advantages    Application:
1. These products are widely used for wrapping material of all kinds of

heat source (coal, electricity, oil, and gas) and heat-presentation of

central air-conditioning pipelines.
2. It can be used as the materials for heat-isolation and fire-

resistance.
3. It can be used as the materials for seal, sound absorption filtering

and insulation.
4. Excellent material for heat-conducting, heat-presentation.
5. It can be used as materials for sound isolation, heat insulation and

heat-
6. It can also be used for touching fire and all kinds of flue in which

the temperature is less than 600.
Product Description
Fiber made from melted glass that is drawn into a thin fiber less than a

thousandth of an inch in diameter. The fiber may be spun into threads

and woven into fabrics which suitable for many applications ,such as

removal of micron and submicron size particulates from both liquids and

gases,or used in an acoustic, electrical, or thermal insulating

material.

Feature:
1. Lightness, heat resisting, low thermal capacity and low thermal

conductivity, soft and excellent fire-isolation.
2. Anti-heat energy and heat stability.
3. Anti-mildew, anti-insect, un-scattered and good stretching

resistance.
4. Excellent anti-ageing.
5. Excellent sound absorbability, adsorption and filtering.
6. It can be cut, sewn according to requirements and it's also easy to

construct.
