Polarizer Manufacturers Explain: What Are The Materials Of Each Layer Of Polarizer

  Polarizer is an optical film made of high-tech polymer composite material. Usually, polarizer manufacturers have certain requirements for the material when producing polarizer. Polarizers produced by polarizer manufacturers usually have polarizing layer, TAC layer, adhesives, protective film and reflective film.

Polarizer manufacturers explain: What are the materials of each layer of polarizer?

1、The polarizing layer usually uses PVA (polyvinyl alcohol)

Polarizer manufacturers usually use PVA (polyvinyl alcohol) to make polarizing layer when producing polarizing film. This polarizing had been made by dyeing and stretching PVA film, which determines the transmittance and polarizing performance of polarizing film, and polarizing film manufacturers usually use dyeing method of dyeing and iodine system.

2、TAC layer usually uses TAC (cellulose triacetate)

Polarizer manufacturers are aware that the TAC layer is made of TAC (cellulose triacetate), because the PVA film in the polarizing layer tends to fade and absorb water, which affects the polarizing performance. The function of glare.

3. Adhesives, release films, protective films and reflective films usually use PET

  Polarizer manufacturers are aware of the use of adhesives, peel-off films, protective films and reflective films in the composition of polarizers. The main function of reflective film is to obtain the effect of mirror reflection, and protective film is needed to play a certain role in the protection of TAC film. The peel film is to protect the pressure-sensitive adhesive layer, while the adhesive is to ensure the adhesion performance of the polarizer. These important components are mainly made of PET (ethylene terephthalate) with silicon coating on one side.
