Isicelo

Ukusetshenziswa ekulungiseleleni imithi noma ezinqubweni zokulungiselela:

I-Polyvinyl alcohol isetshenziswa kakhulu ekulungiseleleni okufakwe ngaphakathi nangaphandle kwamehlo;

I-polyvinyl alcohol ingasetshenziswa njengesiqinisi kuma-emulsion.

I-polyvinyl alcohol isetshenziswa futhi njenge-tackifier kumalungiselelo aqinile njengemikhiqizo yamehlo.

I-Polyvinyl alcohol isetshenziselwa ukugcoba ezinkingeni zokwenziwa kanye nezixazululo ze-contact lens, futhi isetshenziswa nasezilungiselelweni zomlomo ezikhishwa njalo kanye nama-transdermal patches.

I-polyvinyl alcohol ingaxutshwa nesisombululo se-glutaraldehyde ukuze kwakhiwe ama-microspheres.
