Tunsing High-Efficiency Bonding in Multiple Fields: DS7161 Self-Adhesive Acrylic Pressure-Sensitive Adhesive Film

SHENZHEN, CHINA —— Recently, Shenzhen Tunsing Plastic Products Co., Ltd. officially released its next-generation hot melt adhesive film product—DS7161 Self-Adhesive Acrylic Pressure-Sensitive Adhesive Film. With excellent physical properties, broad material compatibility, low processing temperatures, and easy processing characteristics, this product provides an ideal comprehensive solution for high-precision bonding needs in modern industrial manufacturing.

DS7161 is a high-performance, self-Adhesive acrylic pressure-sensitive adhesive film. Structurally, it features a scientifically engineered three-layer composite design consisting of a protective film, a core acrylic pressure-sensitive adhesive layer, and a release paper (Glassine release paper). Thanks to this configuration, DS7161 exhibits exceptional self-adhesive performance at room temperature, greatly simplifying preliminary assembly and positioning workflows.

As an industrial-grade high-performance adhesive film, DS7161 meets rigorous technical specifications across all core metrics:

In Tunsing’s laboratory testing—utilizing a NETZSCH DSC214 testing instrument at a heating rate of 10°C/min under a nitrogen atmosphere—the film demonstrated a clear endothermic effect near -22.8°C. This confirms its low glass transition temperature, ensuring the product retains outstanding flexibility and substrate conformity even in low-temperature environments.

To assist manufacturers in achieving optimal bonding strength, Tunsing’s engineering team recommends the following precise processing parameters:

• Initial Backing (Flat Pressing):

  • Mechanical Mold Temperature: 90°C

  • Hot Pressing Time: 5 - 15 seconds

  • Pressure: 0.3 - 0.6 MPa

• Secondary Lamination (Flat Pressing):

  • Mechanical Mold Temperature: 110°C - 150°C

  • Hot Pressing Time: 10 - 30 seconds

  • Pressure: 0.3 - 0.6 MPa

Technical Note: Bonding temperature, pressure, and time directly dictate the final bonding strength of the film. Because conditions will vary between different machinery and materials, the most ideal parameters should be established through tailored application testing.

DS7161 exhibits outstanding bonding affinity to textiles, metals (such as copper, aluminum, iron, and stainless steel), and plastics (including PVC, PC, ABS, etc.). Leveraging this versatile performance, it is widely utilized across the following key industries:

• 3C Electronics & 5G: Component bonding, housing assembly, and internal fixture attachment.

• Automotive & Precision Instruments: Interior trim bonding and micro-component stabilization.

• Medical Equipment & Sporting Goods: Safe, reliable, and durable structural or skin-contact laminating.

• Luggage & Traditional Manufacturing: Improving the fabrication efficiency of composite fabrics.
