Le film optique PVA est un film polarisant compos\u00e9 de r\u00e9sine PVA, de plastifiant, d'antioxydant et d'autres additifs dissous dans l'eau, puis coul\u00e9 et s\u00e9ch\u00e9 par une extrudeuse. Le film optique PVA est le mat\u00e9riau de base pour la fabrication des polariseurs, et ses performances d\u00e9terminent directement la qualit\u00e9 des polariseurs. Selon les donn\u00e9es du r\u00e9seau d'information de l'industrie, le co\u00fbt du film optique PVA repr\u00e9sente environ 12% du co\u00fbt total des polariseurs.
