Main Use: As the pesticide intermediate, the dibromomethane is the main raw material for synthesizing new type highly effective and broad-spectrum bactericide, it also is the raw material of large tonnage acaricide. Dibromomethane is a kind of good fire retardant, when add it into the polymer, it can effectively reduces the combustion heat when the plastic's burning.
