4oz fiberglass clothis often compared to asbestos as a fire-resistant insulating material. What is the difference? Is it 4oz fiberglass cloth or asbestos cloth?


4oz fiberglass cloth


1. Different materials:

4oz fiberglass cloth is an excellent performance of inorganic non-metallic materials, asbestos is a natural fibrous silicate mineral collectively.


2. Different acid resistance:

Asbestos has acid resistance, alkali resistance, and heat resistance, but also heat and electricity poor conductors. Serpentine asbestos of which the alkali resistance is good, almost no alkali corrosion, but poor acid resistance, very weak organic acid will be able to precipitate magnesium oxide in asbestos, asbestos fiber strength decline. 4oz fiberglass cloth is generally only corroded by concentrated alkali, hydrofluoric acid, and concentrated phosphoric acid.


3. Different tensile strength:

The axial tensile strength of the asbestos fiber is high, and it can reach 374 × 10 ^ 4 kg/m ~ 2 when it is made of asbestos fiber, but it is not crease-resistant. After several creases, the tensile strength decreases significantly. The greatest feature of 4oz fiberglass cloth is its high tensile strength. The tensile strength is 6.3-6.9 g/D in standard conditions and 5.4-5.8 g/d in wet conditions. The density is 2.54 g/cm3. It has a good heat resistance and has no effect on strength when the temperature reaches 300 °C.
