Low-Temperature Bonding Technology! Launches DS9164 High-PerformancePolyurethane Hot Melt Adhesive Film

Shenzhen — Shenzhen Tunsing Plastic Products Co., Ltd., a global leading manufacturer of hot-melt adhesive materials, has officially announced the launch of its new-generation DS9164 High-Performance Polyurethane (PU) Hot Melt Adhesive Film.

As a thermoplastic film-like hot melt adhesive supported by release paper that can be repeatedly heated and plasticized for bonding, DS9164 delivers an efficient and reliable industrial-grade bonding solution for industries such as clothing, embroidery, footwear, bags, handbags, toys, hats, and sporting goods, thanks to its unique low melt flow index, outstanding cold resistance, and superior adhesion to textiles, TPU, PVC, PC, and ABS.

Using professional equipment such as a Differential Scanning Calorimeter (DSC) and a rotational rheometer, the Tunsing Laboratory conducted rigorous testing on DS9164, yielding impressive core physical and thermodynamic performance indicators:

1. Strong Adhesion to Multiple Heterogeneous Materials: DS9164 exhibits extremely high peel strength on textile fabrics as well as hard-to-bond substrates like TPU, PVC, PC, and ABS (for instance, a 0.08mm film laminated on PU cloth, peeled, and then laminated onto PC can achieve an exceptional peel strength of approx. $155\text{ N/25mm}$).

2. Low Flow Value and Easy Processing: Equipped with a lower melt flow index and stable rheological characteristics, the product effectively prevents adhesive overflow and seepage during heat pressing, keeping product appearances refined and clean.

3. Extreme Low-Temperature Resistance: Benefiting from a glassion transition temperature of $-45.4^\circ\text{C}$, the adhesive film resists embrittlement and cracking in harsh outdoor supplies, winter sports equipment, and cold storage environments.

4. Repeatedly Plasticizable and High-Quality Release: Supported by high-grade Glassine Release Paper, it supports repeated heat plasticization and secondary processing, making operation convenient and efficient.

To achieve ideal bonding strengths, it is recommended to adopt the following baseline construction conditions tailored to different production stages:

• Activation Temperature: $90^\circ\text{C} - 150^\circ\text{C}$

• First Lamination: Mechanical mold temperature $130^\circ\text{C} - 180^\circ\text{C}$, time $5 - 15\text{ seconds}$, pressure $0.3 - 0.6\text{ MPa}$

• Second Lamination: Mechanical mold temperature $140^\circ\text{C} - 180^\circ\text{C}$, time $8 - 25\text{ seconds}$, pressure $0.3 - 0.6\text{ MPa}$

Note: Due to variations in mechanical equipment and specific materials, customers are advised to conduct targeted process verification prior to formal mass production.

As an original source manufacturing enterprise integrating R&D, production, and sales of hot-melt adhesive materials, Tunsing remains committed to providing global clients with stable, high-performance material support:

• Rigorous Quality Control Systems: The factory is equipped with advanced experimental testing instruments, and every batch undergoes precise rheological and thermodynamic performance testing prior to shipment to ensure consistent quality.

• Empowering Diverse Industry Applications: Products widely serve traditional garments, footwear, luggage, and handbags, while deeply penetrating modern industrial sectors such as consumer electronics accessories, toy manufacturing, and high-end sporting goods.

• Efficient Supply Chain Services: Headquartered in Pingshan District, Shenzhen, Tunsing relies on mature automated production capacity and spot inventory reserves to provide global clients with highly competitive factory-direct pricing and high-response services.
