Recently, Wanhua Chemical, in collaboration with industry partners, has successfully launched a full MDI molding tray for display panels, achieving mass production application in leading domestic display panel enterprises. This marks a significant breakthrough for MDI molding trays in the high-end electronics manufacturing sector, providing the panel industry with high-performance, versatile green logistics solutions.
Display panels, as a core component of consumer electronics such as TVs, monitors, tablets, and smartphones, have stringent requirements for cleanliness, flatness, and environmental stability of packaging materials during production and transportation. Addressing the limitations of traditional Japanese-style wooden pallets used in the industry for a long time, Wanhua Chemical has jointly developed a specialized product for the display industry - the "Japanese-style double-sided MDI molding tray."
This tray uses Wanhua Chemical's innovative WANNATE® 9131FC eco-adhesive and WANALYST® KC201 efficient demolding agent, primarily made from recycled wood materials and wood processing residues, formed through high-temperature and high-pressure molding processes. Compared to traditional molding trays, MDI molding trays significantly enhance moisture resistance, structural stability, and cleanliness:
Excellent moisture resistance: Maintains excellent mechanical properties under extreme conditions such as high temperature and high humidity, and water splashing, with strong load-bearing capacity and resistance to deformation.
Clean and dust-free: Smooth surface with no debris, meeting the cleanliness requirements for display panel production.
Patented structural design: Innovative "flat panel + 15-foot support base" structure, balancing the extremely flat panel with the convenience of stacking with a nine-foot tray, significantly reducing logistics and storage costs.
Automation compatibility: Developed for various scenarios, compatible with automated transmission lines, vertical warehouses, and other intelligent logistics systems, empowering intelligent manufacturing upgrades.
Disassemblable design: Standardized screw interfaces for later disassembly, reuse, and recycling, reducing the total lifecycle cost.
The MDI molding tray not only performs exceptionally but also has significant environmental advantages: a wide range of raw materials, making full use of waste wood, forestry residues, and other renewable resources; high-temperature molding processes ensure product appearance and batch stability while meeting quarantine exemptions, export without fumigation.
Since Wanhua Chemical introduced the MDI molding tray solution in 2023, it has quickly gained market recognition for its high strength, high weather resistance, and green and low-carbon characteristics. The successful application in the display panel field is not only a significant expansion of the product application scenario but also sets a new benchmark for the high-quality development of the molding tray industry.
In the future, Wanhua Chemical will continue to work with ecological partners to develop specialized and customized tray solutions for more high-end fields such as photovoltaic, new energy, and precision instruments, promoting a new journey of green logistics with innovative material technology.
