Product Definition and Technical Advantages
The Ionoplast Interlayer is a polymer material based on an ethylene-methacrylic acid copolymer. It achieves strong bonding with glass through ionic bonds. It possesses characteristics of high transparency, strong weather resistance, and excellent mechanical properties. Its core advantages include:
1. Ionic Bond Bonding Technology: The bonding strength is five times that of traditional PVB film, the tear strength is five times that of PVB, and the hardness is increased by a hundredfold.
2. High Transparency and Weather Resistance: The light transmittance exceeds 90%, and it can endure a temperature range of -40℃ to 150℃ without yellowing or absorbing water and swelling over extended use.
3. Data Support: The equivalent thickness of laminated glass is reduced by 40%, the bearing capacity is doubled, and the bending deflection is reduced to one-quarter of that of PVB.
Target Customer Positioning and Scene Adaptation
1. Construction Field: High-rise and public buildings focus on curtain wall safety upgrades and promote the "safety performance improvement + cost optimization" solution. Case studies indicate that using SGP film can reduce glass thickness by 40% and decrease building loads.
2. Automobile Field: Light weighting of new energy vehicles. For electric vehicle windshields, the emphasis is on being "30% lighter than PVB, with 2 times more impact resistance," and expanding overseas customers in conjunction with EU ECE R43 certification.
Value-Added Services
We provide a one-stop solution of "materials + processing," such as supporting laminated glass production lines, shortening the customer procurement cycle, and ensuring a 24-hour technical team response to needs. Customized roll width and length options help customers reduce material waste during lamination and save costs.
Trend Response and Forward-Looking Layout
In 2025, the market size of ionic intermediate membranes in China is expected to exceed 8 billion yuan, with a compound annual growth rate of 18%. The recognition of domestic membranes in Southeast Asia and the Middle East has increased, and overseas revenue is expected to account for 30%. The country's "dual carbon" goals have promoted the development of new energy and green building materials, and ionic membranes have received key support. In the future, with the deepening of the "dual carbon" policy and the growth of new energy demand, the application of ionic membranes in energy storage and electronics will become a new growth point.
