Polyacrylonitrile is an acrylic homopolymer, known as acrylic in filtration, is made from 100% acrylonitrile.
The main advantage of acrylic fiber (polyacrylonitrile) is its excellent resistance to hydrolysis, its low cost compared to high-performance fibers and relatively high thermal stability. Acrylic is not hydrolyzed, many applications use water repellent treatments to reduce tendencies of adhesion of moisture or rainfall.
