Environmental glass wool

  • Introduction
  • Parameters

FUERDA glass wool is made by adopting unique centrifugal technology and adding environmental adhesives of thermosetting resins-based into molten glass fibrosis. It is a kind of elastic glass fiber product made of glass fiber with diameter of only a few microns, and we can also choose moisture-proof facing on-line compound according to customers' requirements. Because of a large number of tiny air interspaces, it has the functions of heat insulation, sound absorption, safe guarding and etc, so it is the best materials of heat insulation and sound absorption in construction.


Distinctive advantages: 
 •  It is tasteless, nontoxic and harmless without formaldehyde, ammonia or benzene, which completely improves our working environment.
 •  Sound absorption and noise reduction; it can effectively prevent sound from spreading.
 •  Soft and long glass fibers can maximally lessen flying catkins in the construction.
 •  Grade A1 incombustible materials.
 •  Antisepsis, ageing resistance, and anticorrosion, ensuring a healthy environment.
 •  Low moisture absorption; stable physical properties.


Scope of application:
It is widely used for heat insulation and sound absorption in fans, ovens and other equipments' interlining.


Packing:
FUERDA environmental glass wool adopts transparent water-proof packing. To meet the need of requirements of logistics distribution, the products adopt new technology in compression and packing strength and etc. Compression ratio is 1:5.
