Flame resistant sleeves are typically constructed from inherently flame resistant materials, such as Nomex, Kevlar, or PBI, which can withstand high temperatures and resist ignition.

Flame resistant sleeves are essential for industries where workers are exposed to potential heat or flame hazards, such as welding, chemical processing, firefighting, and manufacturing.

The level of protection offered by flame resistant sleeves varies depending on the materials used and design. They are typically rated according to standards such as NFPA 70E or ASTM D6413, which specify their resistance to specific heat levels and flame durations.

Proper care and maintenance are crucial to ensure the effectiveness of flame resistant sleeves. They should be regularly inspected for any damage or wear, laundered according to the manufacturer's instructions, and stored in a dry and clean environment.
