The features and main use ofile
glasswool products
Main features:
　The glasswool is the fiber of melted glass.It's chemical component is belongs to glass.It is a kind of inorganic fiber.It has many good characters as lower density lower heat conduction number ,good thermal insulation number and sound-absorbing ability ,anti-fire,endure high temperature,anti-freeze,anti-insect,anti-corrosion,better chemical stability.
The glasswool has the following features:
　1).It has good heat insulation ability both at high temperature and at low temperature .It's heat conduction number is low .at 70°C the heat conduction number of the products with density of 24kg/m3is 0.038W/m﹒k .That is tested by the national glasswool quality test centure.
　2).Uncombustible, doing not produce toxi-gas.according to the certificate of national anti-fire system and national quality test center, Huadeli glasswool products are A grade uncombustible.
　3).The products have good recovery ability.
　4). The products have good sound-absorbing noise-reducing ability at medium,low and high frequency.
　5).The products have low humidity absorbing rate.
　6).The products have low line-expansion coefficient.
　7).The product's aging time is long.After a long time of use, the products could still maintain the original feature.
　8).The products are easily to be used.
Main use
The glasswool products could be widely used in national defence,petrochemical, construction,metal melting, cold storage transportation and in other industry.
