Production Technique
The centrifugal glass wool felt is a product made in a process in which glass fiber is made from molten glass using the patented centrifugal method and processed with addition of environmental adhesive mainly omposed of the mosetting resin.It is an elastic felt-like mass piled up with glass fibers only a few in diameter,with possibility of applying moisture-proof facing on the production line according to requirement.
Product Characteristics
It maintains the heat insulating and preserving function and has very good shock reducing and sound absorbingproperty.It especially effective for medium and low frequency shocks and noises and is a good product for reducingnoise pollution and improving work environment. Glass wool felt with aluminum facing has strong capacity to resistheat radiation and is an excellent material for the inner lining for high temperature workshops,control rooms,inner wall,compartments and ceiling of equipmentrooms.
