Tunsing NewDS8111 Polyurethane Hot Melt Adhesive Film: Leading Efficient Bonding Solutions with Exceptional PerformanceT

Recently, Shenzhen Tunsing Plastic Products Co., Ltd. officially released its high-performance hot melt adhesive film product, DS8111. As an eco-friendly polymer bonding material primarily composed of Polyurethane, DS8111 is becoming an indispensable bonding solution for textiles, footwear, and apparel manufacturing industries due to its excellent physical characteristics, processing adaptability, and wide material compatibility.

• Multi-Material Excellent Bonding: DS8111 demonstrates outstanding adhesion to a variety of substrates, including textiles, TPU, PC, and PVC.
• Superb Physical Performance: Once bonded, this hot melt adhesive film gives composite materials a good soft feel and excellent resilience.
• Great Cold Resistance: The product features good cold resistance, ensuring that the finished products maintain a stable bond even in low-temperature environments.
• Repeatable Heating and Plasticizing: Supported by a release paper, DS8111 is a thermoplastic hot melt adhesive film that can be repeatedly heated and plasticized, significantly enhancing production flexibility.
• Wide Range of Applications: This product is widely used for bonding materials in clothing, embroidery, footwear, luggage, handbags, toys, hats, and sporting goods.

To meet the precise processing demands of industrial manufacturing, DS8111 provides strictly verified physical and thermal performance parameters:

• Color: Completely transparent.
• Proportion: 1.18 ± 0.02 g/cm³.
• Hardness: 75 ± 2 (Shore A).
• Melt Flow Index: 10 ± 5 cm³/10min (Test Standard: ASTM D1238-04).
• Melting Range: 80–110°C (Test Standard: ISO11357).
• Glass Transition (TG) Temperature: The standard parameter is -28 ± 10°C (Test Standard: GB/T 19466.2-2004), and a distinct endothermic effect appears near -25.8°C in Differential Scanning Calorimetry (DSC) analysis.
• Activation Temperature: 102–142°C.
• Flow Transition Characteristic: Rheometer dynamic mechanical measurements show that the transition temperature from a viscoelastic solid to a viscoelastic fluid is approximately 105.1°C.

DS8111 provides great production flexibility in terms of product specifications to fully match various processing equipment widths and thickness requirements:

• Release Protection Layer: Utilizes high-quality Glassine Release Paper.
• Thickness Range: Custom production ranges from 0.03mm to 0.15mm, with conventional thicknesses of 0.05mm, 0.08mm, and 0.10mm readily available.
• Width Range: Custom widths range from 5mm to 1480mm, with a conventional standard width of 1380mm.
• Conventional Length: Standard roll length is 100 yards.
• Finished Product: Standard finished roll specification is 1380mm * 100 yards/roll.

According to Tunsing Laboratory tests, to achieve the ideal peel strength, a two-step lamination process is recommended:

• First Lamination: Recommended mechanical mold temperature is 130°C–170°C, time is 5–15 seconds, and pressure should be maintained at 0.3–0.6 MPa.
• Second Lamination: Recommended mechanical mold temperature is 140°C–180°C, time is 8–25 seconds, and pressure should be kept at 0.3–0.6 MPa.

Notice: Bonding temperature, pressure, and time are closely related to the final bonding strength. Since bonding conditions vary across different machinery and materials, the parameters provided here are only basic guidelines. Manufacturers are strongly encouraged to conduct detailed verification and establish the ideal bonding conditions for their specific applications before large-scale production.
