Why is general insulation material considered fireproof? It's not always the case. Most traditional insulation materials contain a significant amount of organic components, especially polymers. These polymer chains are made up of many carbon atoms, which makes them highly flammable. This is similar to hydrocarbons, which are known for their combustibility. The more hydrocarbon molecules you link together, the more likely they are to catch fire and burn rapidly.
What about the fire performance of modified phenolic insulation material? Fire resistance is one of the most critical features of modern insulation products. Different materials have varying levels of fire performance, and the mechanisms behind this can be quite different. The Shangchun modified phenolic insulation material is classified as B1 grade, which means it is considered "difficult to ignite." In the event of a fire, it does not catch fire, melt, or spread the flames. It remains stable, doesn’t drip, doesn't emit smoke, and doesn’t release toxic substances. This makes it a safe and reliable choice for insulation. When exposed to fire, the surface of this material forms a carbonized layer, which helps to slow down the combustion process. According to fire protection regulations, materials with an oxygen index above 26% are considered non-combustible, while those below 26% are classified as combustible. The modified phenolic material meets high safety standards, offering excellent fire protection properties without compromising on thermal efficiency.
Steel Mesh Polyethylene Composite Pipe
Cross helically wound steel wires reinforced-polyethylene composite pipe (SRCP) is a kind of composite metal plastic pipe with excellent overall performance. With excellent pressure bearing performance, good flexibility, long-term resistance to acid and alkaline corrosion and abrasion, it is suitable for long-distance underground pipes for water supply and drainage, slurry transportation and the like, especially for subsidence region such as mining area, river channel.
