General Characteristics

‘KURALON’ is a synthetic fiber made from polyvinyl alcohol polymer, which is normally a water soluble polymer. By use of a special spinning technology, Kuraray is able to supply both water soluble and water insoluble ‘KURALON’ fibers for paper industry. Water soluble types work  as a binder in the paper making process, and water insoluble types work as subject material or the matrix of paper. Water soluble types can be provided over a range of dissolving temperatures. The general characteristics that make PVA useful in papermaking applications include:

l        Good dispersion

l        Dissolves in water ( binder fiber )

l        Good bonding effect ( binder fiber )

l        Improves paper strength

l        Good resistance to alkaline conditions
