FB 4802 is a inherently fire retardant knitted fire barrier that facilitates compliance with open flame tests such as CA TB 129 ,CA TB 133 and CFR 1633 . Unlike competitive FR barriers, FB 4802 is easy to upholster because it stretches around corners and cuts easily with standard scissors . As a inherently FR barrier, working with FB 4802 will not cause irritation to upholsters’ hands.
The barrier’s knit construction provides a soft hand that will not compromise the performance of the foam. FB 4802 moves with the foam and fabric so they do not break down over time and will not cause irritation to upholsters’ hands.
