3.5 Polyvinylalcohol (PVA)

Organic synthetic polyvinylalcohol fibers (PVA - fibers, PVA fraction at least 85%) can be made water insoluble through combination with aldehydes. The fiber diameters typically lie between 10 pm and 20 pm and are therefore not penetrable to lungs. Data on the lengthwise splitting do not exist, however it may be assumed that this does not occur. PVA- fibers are applied in the building area for reinforcement of fiber cement products (Fraction 2 %).
