Transportation:Avoid sunlight, rain, heavy pressure, and severe vibration during transportation.

Shelf life:The normal storage shelf life is two years. After unpacking, it can be stored for three months in a constant temperature dehumidification room with a temperature of 18-25 ℃ and a relative humidity of less than 25%

Introduction to the Performance of Ionic Intermediate Membranes with the Same Shield

Ionic intermediate film is an ionic film made from a copolymer of ethylene and methacrylate, containing trace amounts of sodium metal ions. The bonding force between the film and glass is mainly the result of ion bonding, so the bonding strength between the ionic intermediate film and glass is much higher than that of PVB film and glass. Moreover, its hardness is 100 times stronger than that of traditional PVB interlayer materials, and its tear strength is 5 times higher than that of PVB interlayer materials. The ion type intermediate film developed by Tongdun has high adhesion, optical, and mechanical properties, which can fully meet the needs of the laminated safety glass industry for intermediate films. Compared to PVB membrane, ion polymer membrane laminated glass has the following characteristics:

● Higher strength

Compared with PVB film laminated glass, the same shield ion polymer film laminated glass has higher bending strength. It has higher load and wind pressure resistance performance under the same glass structure and thickness.

● * * * deflection, greater equivalent glass thickness

Due to its high strength, it can be achieved in architectural design with the same deflection requirements, and the same shield ion polymer film laminated glass can be achieved with a smaller glass thickness. It is beneficial for reducing the weight of glass and the weight of the entire support system.

Better safety after crushing.

Ionic polymer membranes have higher tensile and tear strength, and their laminated glass also has strong support after crushing.

● Better optical performance.

Ionic polymer membranes have higher transmittance, * * * haze, and lower yellow index. Composite with ultra white glass has higher permeability and visual effects.
