Flame-retardant chemical protective clothing, also known as acid and alkali-resistant suits or toxic and chemical protective suits, is worn by workers during operations in hazardous chemical or corrosive material environments to protect themselves from the harmful effects of chemical hazards or corrosive substances.

The flame-retardant chemical protective suits are made with a main adhesive tape of aramid silk fabric treated with flame-retardant and adhesive, coated on both sides with flame-retardant and chemical-resistant surface glue. The main adhesive tape only carbonizes upon contact with fire, does not drip, and maintains good strength. The main adhesive tape is produced through a lamination-sewing-tabbing process, forming the suit's main body and gloves, complemented by flame-retardant, voltage-resistant, and puncture-resistant boots, or fire-resistant rubber boots, to complete the full suit set.
