They are used in a wide array of products including electronics (circuit boards, casings), textiles (furniture, curtains, children's nightwear), building materials (insulation, upholstered furniture), and transportation (car seats, aircraft interiors).

While most are chemical additives, some physical mechanisms (like intumescent coatings that swell to form an insulating char) also act as flame retarders. The term broadly encompasses any agent that retards flame.

Certain chemical flame retarders, particularly some brominated and chlorinated types, have been linked to environmental persistence, bioaccumulation, and potential health risks, leading to regulatory restrictions and a push for greener alternatives.
