Fire Retardant Tape
Fire Retardant Tape KC77

KC77 Fire Retardant Tape is a flexible tape with high expansion rate, fire prevention and heat insulation. It is mainly used for fireproof plugging of cracks around single or cluster cables, wind pipe, plastic pipe penetrations and metal penetrations. It has good water resistance, acid and alkali resistance, moisture and heat resistance, and freeze-thaw resistance. It is free of volatile organic matter, asbestos, fiber dust and other harmful substances, safety and environmental protection without pollution. It uses the combination of chemical expansion and physical expansion technology, rapid expansion in case of fire, with the rise of temperature formed with the strength of the carbonization layer tightly filled through the holes of the gap, block the spread of flame and smoke, with more than 3 hours of fire aging. At the same time, the product in the harsh, dirty and other outdoor environment, still can maintain the normal fire function.
