Dynel

Dynel is a trade name for a type of 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. 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.
