Types and sizes of glass wool

Glass wool is divided into three types, glass wool board, glass wool tube, glass wool roll felt

1. Glass wool board is a plate-like material formed by applying phenolic resin adhesive to glass wool felt, pressurizing and heating, and the surface can be pasted with PVC film fabric or aluminum foil. The product has the characteristics of light capacity, large sound absorption coefficient, flame retardant, etc., and has good chemical stability.

Features: light bulk density, large sound absorption coefficient, small thermal conductivity, non-combustible and flame retardant, good chemical stability, good comprehensive characteristics, superior to other thermal insulation and noise reduction materials in the field of medium and low temperature.

Bulk density: 24-96kg/m3 Thickness: 15-100mm

Length: 600-2400mm Width: 600-1200mm

Uses: thermal insulation and cold insulation of roof buildings; entertainment venues, theaters, television stations, radio stations, laboratories, sound-absorbing treatment; insulation of air-conditioning pipes, refrigeration and refrigerated warehouses

2. Glass wool tube is a filamentous material made of molten glass by centrifugal blowing method, which is fiberized and sprayed with thermosetting resin, and then processed by thermal curing to make a series of products with various uses. It has many advantages such as flame retardant, non-toxic, corrosion resistance, small bulk density, low thermal conductivity, strong chemical stability, low moisture absorption rate, and good hydrophobicity. very wide range of uses. Plates, tubes and felts made of this material have been widely used for thermal insulation, sound absorption and noise reduction in the fields of construction, chemical industry, electronics, electric power, metallurgy, energy, transportation, etc., and the effect is very significant. This product is a glass wool with resin adhesive, heated and cured into a tubular thermal insulation material, and the surface can be pasted with aluminum foil, which has the characteristics of moisture-proof and radiation-proof.

Centrifugal glass wool tube is specially used for the insulation of various pipelines (including: freezing, hot water, steam) systems, and can work normally at an ambient temperature not higher than 454 °C, both exposed and concealed.

Because the pipe sleeve of this material has the characteristics of waterproof, anti-corrosion, mildew-free and insect-free, it can effectively prevent condensation and prevent pipeline freezing. It is widely used in civil buildings, thermal pipelines, air-conditioning and refrigeration equipment. , the energy saving effect can be increased by 15-30%. This product is a felt-like material formed by applying adhesive to glass wool and heating and curing. Its bulk density is lighter than that of plates, has good resilience, is cheap, and is easy to construct.

Bulk density: 30-80kg/m3

Inner diameter of tube shell: 22-1200mm

Thickness: 30mm-100mm

Uses: Mainly used for heat preservation and cold preservation in petroleum, chemical industry, electric power, industrial heating, civil heating, etc.

3. Glass wool felt is a coil material made to meet the needs of large-area laying. In addition to maintaining the characteristics of thermal insulation, it also has excellent shock absorption and sound absorption characteristics, especially for medium and low frequency and various vibration noises. All have good absorption effect, which is conducive to reducing noise pollution and improving working environment.

This material can be arbitrarily tailored according to needs during construction, and is mainly used for shock absorption, sound absorption and noise reduction in building interiors, noise reduction systems, vehicles, refrigeration equipment, and household appliances, and the effect is very ideal. The glass wool felt with aluminum foil veneer also has strong anti-heat radiation ability, which is a good lining material for high temperature workshop, control room, machine room inner wall, compartment and flat roof

Bulk density: 9-32kg/m3 Thickness: 15-100mm

Length: 3m-20mm Width: 1200mm

Uses: used for fireproof, heat insulation, sound-absorbing high-rise buildings and refrigeration and air-conditioning rooms, vehicles, ships, etc.
