Application

Kushandiswa mukugadzirira kwemishonga kana maitiro ekugadzirira:

Polyvinyl doro rinonyanya kushandiswa mumusoro uye ophthalmic kugadzirira;.

Polyvinyl doro inogona kushandiswa seyakagadzikana mu emulsions.

Polyvinyl doro rinoshandiswawo se tackifier mune viscous gadziriro senge ophthalmic zvigadzirwa.

Polyvinyl doro rinoshandiswa pakuzora mumisodzi yekugadzira uye yekusangana lens mhinduro, uye inoshandiswawo mumuromo inosimudzira-kuburitswa gadziriro uye transdermal zvigamba.

Polyvinyl doro rinogonawo kusanganiswa ne glutaraldehyde solution kugadzira microspheres.
