Glass yarn plays a vital resistance role in fires

glass yarn has a very serious resistance in fire. The glass yarn material is that the glass yarn itself is not easy to burn, has good alkali resistance, glass yarn has good heat insulation properties, light, good hardness, and good dimensional stability. It is similar to aluminum. The expansion coefficient of bentonite is a flame retardant material. When burned, it produces only a small amount of toxic carbon monoxide gas. It produces a lot of smoke and won't melt due to its low price. It has no distilled content and its production cost is low. 1942,--Experiment made of 300g reinforced Fiber Glass phenolic foam. During World War II, the Germans used phenolic foam to replace light-colored wood in the early aviation industry. During the same period, the British Foam Rubber Company also developed phenolic foam, which was mainly used for flow.

Phenolic foam was used to heat the heads of early missiles and rockets. In recent years, high-rise buildings, transportation, ships, aviation, aerospace technology and other aspects have put forward strict requirements for synthetic foams with good thermal stability and flame resistance, which has led to widespread attention and rapid development of communication on phenolic foam. Now, as a new type of multi-functional phenolic foam, it has attracted people's great attention due to its fire resistance, flame retardant, self-extinguishing, flame retardant penetration, fire content and prevention of fire spread without distillation. People realize that the use of glass yarn to make thermal insulation materials have important practical value in the fields of high-rise buildings, heat insulation, and ultra-low temperature cold preservation.
For the various structures of human existence, security issues have been included in the first batch. --Phenolic foam is a high-performance fireproof, heat-insulating, sound-insulating and light-saving energy-saving product. It has low thermal conductivity and the lowest density of only 30~40 kg/cubic meter. The flame retardant degree of phenolic foam is the polystyrene widely used in buildings at present. Ethylene, such as polyurethane foam, is far inferior; after 1700°C flame spraying for 10 minutes on a 24 mm thick phenolic foam sheet, it was only slightly carbonized, but no surface was burned through, and it could neither attack nor emit smoke and gas.
The French Architecture Technology Center has a comprehensive inspection of phenolic foam, which proves that it is good. For example, the flame resists the flame exceeding 30°C sprayed by the welding gun and is aimed at the foam board. No obvious burns are recorded after two minutes. Come back, no high temperature pyrolysis fumes.
