Para Aramide p-AR

Para-aramids are often blended with other fibers to impart some of their high strength properties to the blend or mix. A 60/40 blend of para-aramide and PBI, is the most widely used material for firemen's premium turn out coats. Para-aramide helps overcome some of the "textile" deficiencies (processing, strength) in the PBI; the PBI's softness, moisture regain, and high temperature properties improves the performance characteristics of para-aramide. And it reduces the cost of the otherwise expensive PBI fiber.

Such synergy is often utilized in high performance fiber blends - one fiber contributing unique properties or improving characteristics of specialized materials - such as improved processing of otherwise difficult-to-handle fibers, or to reduce overall cost.
