3.6 Polypropylene (PP)

Organic synthetic polypropylene fibers (PP - fibers) can be manufactured with diameters of 20 pm to 100 pm and are therefore not penetrable to lungs. Lengthwise splitting is not to be expected. The fibers are applied in the areas of gaskets and structural elements and other construction products, particularly fibrous cement. Trials with fiber mats and fiber fleeces showed, however, that due to the arising separation of layers between mats and cement paste, no satisfactory results could be achieved. In Europe only Moplefan (Italy) still manufactures fibrous cement sheets from short-fibered PP fleeces or PP - fiber and cement paste.
