Para-aramid felt is a high-performance industrial felt made from para-aramid 1414 fiber using a needle-punching process. Its natural color is golden yellow.
Kevlar felt offers ultra-high tensile strength, superior wear resistance, and cut resistance, with better high-temperature performance than Nomex felt. It is widely used for high-temperature conveying, heat insulation, and wear-resistant protection.
