Zhejiang Tongdun New Materials Co., Ltd. is located in Tiantai County, Taizhou City, Zhejiang Province. It is a technology-based company that produces ionomer membranes. The company has established long-term cooperative relationships with Zhejiang University of Technology and the Wenzhou Institute of the University of Chinese Academy of Sciences, etc., and conducts long-term and in-depth research on the development, testing, and application of ionomer membranes.
The company covers an area of 5000 square meters. The existing ionomer membrane production line is designed with an annual production capacity of 1000 tons. It has a dust-free workshop and a first-class product quality monitoring and testing system, as well as a high-quality R & D and testing team. It strictly controls the quality stability from raw materials to finished products. The company is customer-oriented and quality-based. Through continuous in-depth research, it provides more efficient products and services to society.
Packaging and Storage of Tongdun Ionomer Interlayer Film
Packaging : The inner packaging uses aluminized film for vacuum packaging, and the outer packaging uses wooden boxes. Both the inner and outer packages are attached with product information certificates.
Storage: It should be stored in a cool and dry place at a temperature below 30℃, avoiding direct sunlight. If the package is opened or damaged, it should be placed in a constant temperature and dehumidified room at a temperature of 18 - 25℃ 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 normal storage shelf life is two years. After opening the package, it can be stored for 3 months in a constant temperature and dehumidified room at a temperature of 18 - 25℃ and a relative humidity of less than 25%.
Ionomer interlayer film is an ionic film of a copolymer of ethylene and methacrylate, containing a trace amount of sodium metal ions. The adhesion between this film and glass is mainly the result of the action of ionic bonds. Therefore, the adhesion between the ionomer interlayer film and glass is much higher than that between the PVB film and glass, and its hardness is 100 times that of traditional PVB interlayer materials, and its tear strength is 5 times that of PVB interlayer materials. The ionomer interlayer film developed by Tongdun has high adhesion, optical, and mechanical properties, which can fully meet the needs of the laminated safety glass industry for interlayer films. Compared with PVB films, ionomer membrane laminated glass has the following characteristics:
●Higher strength
Tongdun ionomer membrane laminated glass has higher flexural strength than PVB membrane laminated glass. Under the same glass structure and thickness, it has higher load and wind pressure resistance.
● Lower deflection and greater equivalent glass thickness
Due to its high strength, in architectural design, under the same deflection requirement, Tongdun ionomer film laminated glass can achieve this with a smaller glass thickness. It is beneficial to reduce the weight of the glass and the weight of the entire support system.
● Better post - breakage safety.
The ionomer film has higher tensile strength and tear strength, and its laminated glass still has strong support after being broken.
● Better optical performance.
The ionomer film has higher light transmittance, lower haze, and a low yellow index. After being compounded with ultra - clear glass, it has higher transparency and visual effects.
