Dynel is a trade name for a type synthetic fiber used in fibre reinforced plastic composite materials, especially for marine applications. As it is easily dyed, it was also used to fabricate wigs [1] [2]. A copolymer of acrylonitrile and vinyl chloride, it shares many properties with both polyacrylonitrile (high abrasion resistance, good tensile strength) and PVC (flame resistance). It is an acrylic resin.
Dynel was originally produced by Union Carbide corporation.
