Shenzhen Tunsing Release High-Performance DS9164 Hot Melt Adhesive Film rolls bonding cloth patch

[Shenzhen, China] As modern demands for high-quality, eco-friendly seamless bonding continue to grow across textiles, apparel, and composite processing, Shenzhen Tunsing Plastic Products Co., Ltd.—a leading supplier of adhesive solutions—has officially launched its flagship product: the DS9164 hot melt adhesive film.

Formulated with polyurethane, DS9164 is a thermoplastic film-like adhesive backed by release paper that supports repeated heating and plasticization for durable bonding. Designed specifically for seamless construction in garments, embroidery, footwear, bags, toys, hats, and sporting goods, it delivers a stable and efficient laminating experience for global manufacturers.

DS9164 combines exceptional physical performance with versatile processing adaptability:

• High Peel Strength: Provides excellent adhesion to textiles, TPU, PVC, PC, and ABS.

• Controlled Melt Flow: Features a low flow value to ensure clean edges without excess adhesive spill.

• Superior Cold Resistance: Maintains durability and flexibility in low-temperature environments.

• Easy Processing: Offers easy cutting and precise alignment, boosting production efficiency for both automated and manual setups.

To meet precise industrial specifications, Tunsing Laboratory evaluated DS9164 through Differential Scanning Calorimetry (DSC) and rotational rheometry:

• Appearance: Foggy translucent film (protected by Glassine release paper)

• Density: $1.20 \pm 0.02\text{ g/cm}^3$

• Hardness: $96 \pm 2\text{ Shore A}$

• Melt Flow Index (MFI): $3 \pm 2\text{ cm}^3/10\text{min}$ (ASTM D1238-04)

• Glass Transition Temperature ($T_g$): $-45 \pm 8^\circ\text{C}$ (ISO 11357 / GB/T 19466.2-2004) with a DSC test peak near $-45.4^\circ\text{C}$, ensuring excellent low-temperature flexibility.

• Melting Range: $35 - 55^\circ\text{C}$ (Activation Temperature: $90 - 150^\circ\text{C}$).

• Viscoelastic Transition Temperature: Rheometer dynamic testing indicates a storage modulus ($G'$) and loss modulus ($G''$) crossover near $97.1^\circ\text{C}$, where the material transitions from a viscoelastic solid to a viscoelastic fluid for optimal penetration.

DS9164 is available in versatile dimensions to fit varying machinery requirements:

• Conventional Thickness: $0.05\text{ mm}$, $0.08\text{ mm}$, and $0.10\text{ mm}$ (Custom range: $0.03\text{ mm} - 0.15\text{ mm}$).

• Conventional Width: $1380\text{ mm}$ (Custom range: $5\text{ mm} - 1480\text{ mm}$).

• Finished Roll Length: $100\text{ yards/roll}$ (Standard finished product size: $1380\text{ mm} \times 100\text{ yards}$).

1. First Lamination (Applying to substrate prior to peeling release paper):

   • Temperature: $130 - 180^\circ\text{C}$

   • Time: $5 - 15\text{ seconds}$

   • Pressure: $0.3 - 0.6\text{ MPa}$

2. Second Lamination (Final bonding after removing release paper):

   • Temperature: $140 - 180^\circ\text{C}$

   • Time: $8 - 25\text{ seconds}$

   • Pressure: $0.3 - 0.6\text{ MPa}$

(Note: Parameters should be tailored to specific equipment setups and material compositions.)
