INDURA FRC flame resistant coveralls offers a 100% cotton fabric that is engineered to provide optimum performance for industrial thermal protective clothing. To achieve flame resistance, a proprietary treatment process includes applying a flame retardant chemical to the cotton which then forms a long chain flame retardant polymer impregnated into the core of each cotton fiber. The FR Cotton remains soft and comfortable, even after the FR process is achieved. INDURA FRC provides a cost effective alternative to traditional durable FR fabrics, with excellent protection against flame and electric arc.
