SHENZHEN, China – Shenzhen Tunsing Plastic Products Co., Ltd. has officially released the technical specifications for its latest engineering-grade bonding solution: the DS7161 Acrylic Pressure-Sensitive Adhesive (PSA) Film. Designed to meet the rigorous demands of modern industrial assembly, DS7161 combines high-strength adhesion with a low-temperature processing profile to optimize manufacturing efficiency across multiple sectors.
The DS7161 is a self-adhesive acrylic PSA supported by a release liner, exhibiting strong tackiness at room temperature. Its specialized chemical formulation allows for high-performance bonding across a diverse range of substrates:
Metals: Exceptional adhesion to copper, aluminum, iron, and stainless steel.
Plastics: Optimized for bonding PVC, PC, and ABS.
Textiles: Provides reliable structural bonding for various fabric materials.
The film features a sophisticated three-layer architecture:
Protective Film: Ensures the adhesive surface remains pristine until application.
Acrylic PSA: The core functional layer providing high-strength bonding.
Glassine Release Paper: High-quality liner for easy peeling and consistent processing.
Engineered for precision, the DS7161 offers stable physical and thermal properties to ensure reliability in sensitive environments:
Ultra-Thin Profile: Available in standard thicknesses of 0.05mm and 0.08mm, ideal for compact 3C electronics and precision instruments.
Thermal Stability: Features a glass transition temperature (Tg) of -22.8°C (as verified by DSC analysis), ensuring performance stability in low-temperature environments.
Activation Range: The adhesive activates between 70°C and 120°C, allowing for energy-efficient processing that protects heat-sensitive components.
Physical Density: Maintains a consistent specific gravity of 1.0±0.02g/cm3.
To achieve maximum bond strength, Tunsing recommends specific operational parameters tailored to high-speed production lines:
| Process Phase | Temperature | Time | Pressure |
|---|---|---|---|
| Initial Back-Adhesive (Flat Press) | 90°C | 5–15 seconds | 0.3–0.6 MPa |
| Final Bonding (Flat Press) | 110°C–150°C | 10–30 seconds | 0.3–0.6 MPa |
Due to its versatility and ease of processing, DS7161 is currently being integrated into high-growth industries, including 5G telecommunications, 3C electronics, automotive components, medical devices, and high-end luggage.
The product is now available in standard rolls of 500mm * 100 yards. For more technical inquiries or custom verification, please contact Tunsing Engineering at 0755-89960067 or visit
