Tunsing DS6191 Hot Melt Film: Achieving High-Strength Bonding Across Diverse Substrates

SHENZHEN —— As global manufacturing increasingly demands higher efficiency, lower energy consumption, and eco-friendly materials, Shenzhen Tunsing Plastic Products Co., Ltd. has officially introduced its star hot melt adhesive film, DS6191, to the European and American markets. Engineered as a low-temperature bonding solution for modern industrial upgrades, DS6191 stands out as an ideal choice for high-end European and American manufacturing, fashion apparel, and outdoor sports equipment due to its exceptional physical properties and broad material compatibility.

DS6191 is an eco-friendly hot melt adhesive film developed from premium Polyurethane material. It not only delivers outstanding performance in traditional applications like clothing, embroidery, luggage, and handbags, but also demonstrates exceptionally high bonding strength on challenging industrial substrates such as fiberglass sheet, TPU, PVC, PC, and ABS, perfectly solving cross-material lamination challenges.

In alignment with the European and American manufacturing focus on "energy saving, cost reduction," and "automation compatibility," DS6191 offers breakthrough performance:

• Lower Operating Temperature: The activation temperature of the product is only 68°C - 110°C. In actual processing, the recommended mechanical mold temperature for the first lamination requires only 80°C - 120°C, effectively protecting heat-sensitive substrates from thermal deformation.

• Ultra-Fast Curing Efficiency: The first lamination time requires only 5 - 15 seconds at a pressure of 0.3 - 0.6 mpa. This extremely short pressing cycle allows it to fit seamlessly into automated production lines, significantly reducing cycle times.

Thanks to its advanced molecular structure design, Differential Scanning Calorimetry (DSC) testing shows that the glass transition temperature (Tg) of DS6191 is as low as approximately -45±7°C. This ensures that the finished products maintain excellent flexibility and structural integrity even in the freezing winter outdoor environments of Europe and North America, preventing brittle cracking.

To meet the stringent manufacturing standards of European and American industries, DS6191 offers highly diverse specification options:

• Color: Milky translucence.

• Conventional Thickness: Available in multiple standard sizes including 0.05mm, 0.08mm, 0.10mm, and 0.15mm, with a total thickness range of 0.0125mm - 0.15mm.

• Conventional Width & Length: Features a conventional width of 1380mm and a conventional length of 100 yards per roll. It supports precise slitting within a width range of 5mm - 1580mm to flexibly match different molds and roller equipment.

DS6191 is rigorously tested and verified by the Tunsing Laboratory. Various thermodynamic indicators are evaluated through international standard testing methods, such as ISO11357 (Melting Range: 40-55°C), ensuring stable and reliable product quality.

Addressing the rigorous demands of European and American clients regarding manufacturing processes, Tunsing emphasizes that due to physical variations in machinery and substrates, the conditions indicated are basic guidelines. Manufacturers are encouraged to establish the most ideal, customized construction conditions through actual sampling and testing to achieve the finest final bonding quality.
