Tongdun SGP Ionic Interlayer Film
Packaging and Storage of Tongdun Ionic Interlayer Film
Packaging : The inner packaging uses an aluminum-plated film for vacuum packaging, and the outer packaging uses a wooden box. Both the inner and outer packaging are accompanied by a product information certificate.
Storage: It should be stored in a cool and dry place at a temperature below 30°C, avoiding direct sunlight. If the packaging is opened or damaged, it should be placed in a constant temperature dehumidification room at a temperature of 18 - 25°C and a relative humidity of less than 25% and used as soon as possible.
Transportation: During transportation, avoid sunlight, rain, heavy pressure, and severe vibration.
Shelf life: The shelf life under normal storage conditions is two years. After unpacking, it can be stored for 3 months in a constant temperature dehumidification room at a temperature of 18 - 25°C and a relative humidity of less than 25%.
Performance Introduction of Tongdun Ionic Interlayer Film
The ionic interlayer film is an ionic film made of a copolymer of ethylene and methacrylate, containing a trace amount of sodium metal ions. The bonding force between this film and glass is mainly the result of ionic bond action. Therefore, the bonding force between the ionic interlayer film and glass is much higher than that between the PVB film and glass. Moreover, its hardness is 100 times that of traditional PVB interlayer materials, and its tear strength is 5 times that of PVB interlayer materials. The ionic interlayer film developed by Tongdun has high bonding performance, optical performance, and mechanical performance, fully meeting the requirements of the laminated safety glass industry for interlayer films. Compared with PVB films, laminated glass with ionic polymer films has the following characteristics:
● Higher strength
Laminated glass with Tongdun ionic polymer film has higher bending strength compared with laminated glass with PVB film. Under the same glass structure and thickness, it has higher load-bearing capacity and wind pressure resistance.
● Lower deflection and larger equivalent glass thickness
Due to its high strength, in architectural design, under the same deflection requirements, laminated glass with Tongdun ionic polymer film can be achieved with a smaller glass thickness. This helps to reduce the weight of the glass and the entire support system.
● Better post-breakage safety.
The ionic polymer film has higher tensile strength and tear strength. The laminated glass still has strong supportability after being broken.
● Better optical performance.
The ionic polymer film has higher light transmittance, lower haze, and a low yellow index. When combined with ultra-clear glass, it has higher transparency and visual effects.
