Citric acid is a weak organic acid that is commonly found in citrus fruits. As a flame retardant, it works by releasing water vapor when exposed to heat, which dilutes the flammable gases and limits the spread of flames.
Yes, citric acid is considered to be a safe and environmentally friendly option for flame retardants. It is non-toxic, non-corrosive, and biodegradable.
Citric acid can be used on a variety of materials, including textiles, wood, and plastics. However, its effectiveness may vary depending on the material and the concentration of citric acid used.
Citric acid is generally considered to be less effective than traditional flame retardants, such as halogenated compounds. However, it is a more sustainable and environmentally friendly option.
One potential drawback of citric acid as a flame retardant is that it may not be as long-lasting as other options. It may also be less effective in high temperatures or for materials that are prone to dripping and smoldering.
