SAN polymer, with the chemical name styrene-acrylonitrile copolymer, is a versatile plastic that is characterized above all by its excellent transparency and chemical resistance. In addition, it has high stiffness and good dimensional stability which allow it to be used in demanding environments.SAN plastic components can be used with or without further surface treatment in visible areas, such as in the interior of vehicles. The transparency of the polymer is particularly effective in combination with fiber reinforcement, which makes it possible to produce high-quality components with excellent surfaces that also meet the highest visual demands
