Introduction to the performance of ionic interlayer
The ionic intermediate film is an ionic film of a copolymer of ethylene and methacrylate. It contains a small amount of sodium metal ions. The adhesion between the film and the glass is mainly the result of the ionic bond, so the ionic intermediate film and the glass The bonding strength is much higher than that of PVB film and glass, and its hardness is 100 times tougher than traditional PVB interlayer materials, and its tear strength is 5 times that of PVB interlayer materials.
The ionic interlayer film has high bonding properties, optical properties, and mechanical properties, which can fully meet the needs of the laminated safety glass industry for interlayer films. Compared with PVB membrane, ionic polymer membrane laminated glass has the following characteristics:
●Higher strength
Compared with PVB film laminated glass, Tongshi ionic polymer film laminated glass has higher bending strength. With the same glass structure and thickness, it has higher load and wind pressure resistance.
●Lower deflection, larger equivalent glass thickness
Because of its high strength, in architectural design, under the same deflection requirements, the same shield ion polymer film laminated glass can be realized with a smaller glass thickness. It is beneficial to reduce the weight of the glass and the weight of the entire support system.
●Better safety after crushing.
The ionic polymer film has higher tensile strength and tear strength, and its laminated glass has stronger support after being broken.
● Better optical performance.
The ionic polymer film has higher light transmittance and lower haze, and low yellow index. After being compounded with ultra-white glass, it has higher permeability and visual effects.
