The fully-sealed chemical protective suits, also known as acid-base-resistant work clothes, fire protection chemical suits, and thermal insulation protective suits, are worn by workers in environments with hazardous chemicals or corrosive materials to safeguard themselves against chemical dangers and corrosive substances.

The main body of the fully-sealed chemical protective suit is made from aramid fabric treated with flame-retardant and adhesive, coated with flame-retardant chemical-resistant surface adhesive on both sides. The main body of the adhesive only carbonizes upon contact with fire, does not drip, and maintains excellent strength. The main body adhesive 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 chemical-resistant boots, to complete the full suit set.
