What is the difference between Fiberglass Cloth and glass material?
Fiberglass Cloth and glass main material difference is not big, mainly because the production of material requirements are different, so there are some differences in formula. Flat glass silica content in the 70-75 around, glass fiber silica content generally under 60%.
Glass is a high-temperature melting of inorganic materials (more than 800 degrees, daily-use glass is generally in the 1100-degree melting. Below the softening point temperature, no chemical changes occur. Softening point temperature above, also only soften, melt or decompose, there will be no combustion phenomenon.
Fiberglass Cloth is to pull glass into a very fine glass wire, at this time the glass wire has a very good softness. The glass nes into yarn, and then through the loom can be woven into fiberglass cloth. Because the glass filament is very fine, the surface area of the unit mass is very large, so the temperature resistance performance decreases. It's like using a candle to melt a thin copper wire.
But the glass doesn't burn. What we can see is that the combustion is actually to improve the performance of the fiberglass cloth, and the resin material coated on the surface of the fiberglass cloth, or the impurities attached to it. Pure Fiberglass Cloth or coating some high temperature resistant coating, can make fire-resistant clothing, fire-resistant gloves, refractory blanket products. But if you contact the skin directly, the broken fiber will irritate the skin more.
