This product is suitable for high-rise buildings, oil fields, power stations, mines, subways, control and monitoring circuits, and computer systems with high flame retardant requirements. The product is mainly developed and applied through oxygen isolation technology, filling a layer of inorganic metal compounds between cable insulation and outer protective layer. It is a non-toxic, odorless, and halogen-free gel like body. When the cable burns, the originally soft metal compound decomposes upon heating, releasing crystalline water and absorbing heat, and forming a covering layer on the insulation surface to isolate the combustion assisting effect of hot oxygen and protect the inner insulation layer; Crystalline water precipitation, water evaporation
The evaporation of steam absorbs a large amount of heat energy, greatly reducing the temperature of the outer combustible materials and the surrounding environment, causing the cable that is on fire to gradually extinguish on its own.
Production execution standards:
Adopting Q/TK. TY. J.04.15-2001 and GB/T18380.3-2001 standards.
