Polyaramid Fiber (Polymetaphenylene isophthalamide), a fiber from Goodfellow's range, is a synthetic polymer with excellent strength-to-weight properties. With high tensile strength and thermal stability, polyaramid fiber maintains strength and stiffness at elevated temperatures. Common applications of polyaramid fiber include flame and cut-resistant apparel, rope and cable, sailcloth, and composites. The fiber's high strength and heat resistance make it ideal for protective gear and structures exposed to extreme conditions. Within Goodfellow's fiber inventory, polyaramid stands out for its exceptional mechanical performance.
