Isicelo

Ukusetyenziswa kwiinkqubo zokulungiselela amayeza okanye zokulungiselela:

I-Polyvinyl alcohol isetyenziswa kakhulu kwizithako zamehlo nezokucoca amehlo;

I-Polyvinyl alcohol ingasetyenziswa njengesiqinisi kwi-emulsions.

I-Polyvinyl alcohol ikwasetyenziswa njengesithambisi kwizithako ezixineneyo ezifana neemveliso zamehlo.

I-Polyvinyl alcohol isetyenziselwa ukuthambisa kwizisombululo zokwenziwa kwe-drains kunye ne-contact lens, kwaye ikwasetyenziswa nakwizinto zomlomo ezikhutshwa rhoqo kunye nama-transdermal patches.

I-Polyvinyl alcohol ingaxutywa nesisombululo se-glutaraldehyde ukuze yenze ii-microspheres.
