Polyvinyl Alcohol

Description

Polyvinyl Alcohol (PVA) is a synthetic, biocompatible and toxicologically safe polymer.

Polyvinyl alcohol is used for mounting cells on slides for detection of cell-surface antigens by immunofluorescence. It is useful as an anti-fading agent. It has various pharmaceuticle applications. In tablet coatings it protects the tablet from environmental humidity, in eye drops it moistens the eye, and in cell fermentation processes Polyvinyl Alcohol prevents bubble rupture to protect cells from shearing. It is used in textile sizing, adhesives, polymerization aids, and paper coatings.
