1.PVB resin
PVB interlayer film is mainly made of PVB resin. PVB resin is a polymer compound obtained by reacting polyvinyl alcohol and butyraldehyde under the catalysis of strong acid.
PVB resin is non-toxic, odorless, non-corrosive and non-flammable. It has good light transmittance, insulation, weather resistance, wear resistance, water resistance, oil resistance and aging resistance. It has special bonding with inorganic and organic glass. properties and light transmittance. It can be used as a laminated material for safety glass and other transparent materials.
2.Plasticizer
The plasticizer 3G8 used in the production of PVB interlayer film has good compatibility with PVB resin, and has good cold resistance, heat resistance and other characteristics.
3.Additives
In addition to the above two main raw materials, the PVB interlayer film also adds additives such as adhesion regulators, antioxidants, and ultraviolet absorbers in order to adjust the adhesion, improve weather resistance, and isolate ultraviolet rays.

Advantages of Resin: Safety glass produced using all-resin PVB film has superior optical properties, higher light transmittance and lower haze, making the glass product more transparent. For example, using multiple layers of PVB to make laminated glass, all-resin PVB The advantages will be more obvious. Secondly, the yellowing value of the film is very low and the film is whiter, so that the finished glass will not turn yellow and is suitable for ultra-white laminated glass.
The all-resin film is more durable and can withstand the sun and rain. It will not cause degumming, bubbles, aging and other undesirable phenomena after long-term use.
Raw materials are the main elements that affect the light transmittance and durability of PVB film. Because our film is produced from full resin, the polymer substances in the film are not easy to age, which greatly improves the purity of the production materials.
