3.4 Polyacrylnitril

Organic synthetic polyacrylnitrile fibers (PAN-fibers) can be manufactured for technical applications with a diameter above 18 pm. They therefore lie outside the range penetrable to the lungs. A lengthwise splitting under mechanical wear is only conditionally possible. PAN-fibers are used for reinforcement in the areas of filtration, friction linings, structural elements and other construction products (as reinforcement up to 2 % in fibrous cement), etc..
