Low smoke halogen free flame retardant tape is a flame retardant tape material made of glass fiber cloth as the base material, dip-coated with configured metal hydrate and halogen-free flame retardant glue solutions in a certain proportion on its upper and lower surfaces, baked, cured and slit.
The low smoke halogen free flame retardant tape is suitable for use as wrapping tape and oxygen-insulation flame-retardant layer in all kinds of flame-retardant cable and fire-resistant cable. When the cable is burning, the low smoke halogen-free flame retardant tape can absorb a lot of heat, forming a heat insulation and oxygen resistance carbonized layer, isolating oxygen, protecting the cable insulation layer from burning, preventing the flame from spreading over the cable, and ensuring the normal operation of the cable within a certain period of time.
Low smoke and halogen-free flame retardant tape produces very little smoke when burning, and no toxic gas is produced, which will not cause ‘secondary disaster’ during fire. Combined with the low smoke and halogen-free flame retardant outer sheath layer, the cable can meet the requirements of different flame retardant grades.
Low smoke halogen-free flame retardant tape not only has high flame retardancy, but also has good mechanical properties and soft texture, which makes the cable core bind more firmly and maintains the stability of the cable core structure. It is non-toxic, odorless, non-polluting when used, does not affect the current carrying capacity of the cable during the operation, has good long-term stability.
Mainly used as core bundling and oxygen-insulation flame-retardant layer of all kinds of flame-retardant cable, fire-resistant cable.
