Polyvinyl butyral (PVB) is abbreviated as PVB.

1) PVB resin
PVB interlayer is mainly made of PVB resin.
PVB resin is non-toxic, odorless, non-corrosive, non-flammable, has good light transmittance, insulation, weather resistance, wear resistance, water resistance, oil resistance, aging resistance, and has special adhesion and light transmittance to inorganic and organic glass. It can be used as an interlayer material for safety glass and can be used as other transparent materials.
2) Plasticizer
Plasticizer 3G8 used in the production of PVB interlayer has good compatibility with PVB resin and has good cold resistance and heat resistance.
3) Additives
In addition to the two main raw materials mentioned above, PVB interlayer also contains additives such as adhesion regulators, antioxidants, and UV absorbers in order to adjust adhesion, improve weather resistance, and isolate UV rays.
