Supporting continuous operating temperatures of 1800°F (980°C) with peak temperatures to 2300°F (1260°C), Jorhom provides superior protection from sparks and slag and is ideal for stress relieving, stainless steel welding, and equipment protection. The yarn is composed of more than 96% silica for superior temperature resistance. It is then treated with an inorganic coating that improves abrasion resistance and remains with the fabric even at high temperatures.
