теплоизоляция из стекловолокна шерсти ролл

Applications It can be cut into any shape during execution of works. It is mainly used in the shock absorbing, sound deafening or noise reduction treatment in building inteiors,sound deafening vehicles,refrigerating plants and household electrical appliances,offering ideal effect. Production Technique The centrifugal glass wool felt is a product made in a process in which glass fiber is made from molten glass usingthe patented centrifugal method and processed with addition of environmental adhesive mainly omposed of ther-mosetting resin.It is an elastic felt-like mass piled up with glass fibers only a few im in diameter,with possibility ofapplying 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 temperatureworkshops,control rooms,inner wall,compartments and ceiling of equipmentrooms.
