Hanjiang centrifugal glass wool of Chengdu Hanjiang New Building Material Co. Ltd is made from natural minerals such as quartz sand, dolomite, borax and other inorganic material. Mixed in accordance with the requirement of specific technological formula proportion, it can be used to produce a series of products of glass wool blankets and glass wool boards through advanced centrifugal fiber forming technology after high-temperature hot-melting at 1400oC.

Hanjiang glass wool eliminates harm to the human body because of hazardous substance such as formaldehyde in the places with a dense population where plenty of glasswool is used for heat insulation.

It is a kind of glass wool product with high water repellence. At the users different demands, glasswool can be used to produce glass wool series products with high water repellence so as to greatly reduce the possibility that heat insulation and service life of glass wool are reduced because of penetration of water vapor into the glass wool.

It has high resiliency. Glass wool adopts product formula and thermosetting resin with proprietary technology as well as its own good fiber performance makes sure that all the products have good resiliency and the products can recover to the designed thickness after packaging, storage, transportation, installation and use. In accordance with the formula thermal resistance=thickness coefficient of thermal conductivity, the thickness of the heat insulating material plays an important role in guaranteeing the performance of thermal resistance of the product.

It is with high tensile strength. Thinner and longer glass fiber makes the fiber more ductile, closer inter-fiber integration and further improves inter-fiber withdrawal resistance so as to make the product possess higher tensile strength and guarantee uniform distribution of fiber after installation and use without partial insufficient thickness.

It is with the compound moisture-proof facing material on the production line. All the products needing the facing material such as compound aluminum foil, polypropylene film and glass fiber blanket are all make composite molding with one-time pasting on the production line of glasswool. It guarantees sufficient conglutination of the facing material and glasswool and make the facing smooth and elegant.

The fire performance. More than 90% of the raw material of glass wool is natural inorganic minerals, so it possesses excellent fire resistance. Judged from GB8624-2006 of National Quality Supervision and Examination Center of Fire Proof Building Material, all the glass wool products belong to Class A.
