Shenzhen Tunsing Plastic Products Co., Ltd. Launches DS8166 High-Performance Polyurethane Hot Melt Adhesive Film

Shenzhen, 2026 — Shenzhen Tunsing Plastic Products Co., Ltd., a global leading provider of hot-melt adhesive material solutions, officially released its newly developed DS8166 High-Performance Polyurethane (PU) Hot Melt Adhesive Film today.

As a thermoplastic high-polymer bonding material supported by release paper, DS8166 offers exceptional adhesive performance, superior soft feel and resilience, and outstanding high and low-temperature resistance, delivering a high-reliability and cost-effective industrial bonding solution for apparel, embroidery, luggage, handbags, and sporting goods.

Using professional equipment such as the NETZSCH Differential Scanning Calorimeter (DSC) and Anton Paar Rotational Rheometer in the Tunsing Laboratory, strict physical and thermodynamic tests were conducted on DS8166 to ensure consistent product quality across various processing environments:

1. Strong Adhesion Across Wide Applications: DS8166 shows exceptional peel strength and adhesion to textiles as well as engineering plastics like ABS, PVC, and PC, solving industry challenges in bonding dissimilar materials.

2. Soft Hand Feel and High Elastic Resilience: The product retains the inherent soft texture and high elasticity of polyurethane, remaining stiffness-free after heat pressing and perfectly meeting ergonomic and wearing comfort standards.

3. Superior Weather Resistance and Wide Temperature Adaptability: Features good heat and cold resistance, maintaining sound toughness even at -20°C to prevent film cracking.

4. Repeatedly Heat-Plasticizable: Built with a thermoplastic polymer formula equipped with high-quality Glassine Release Paper, making it convenient for rewinding, cutting, and secondary processing while significantly boosting production efficiency.

To achieve optimal peel strength (reaching up to 80 - 100 N/25mm peel force on cotton), refer to the following processing parameters:

• Activation Temperature: 116°C - 168°C

• First Lamination: Mechanical mold temperature 150°C - 180°C, time 5 - 15 seconds, pressure 0.3 - 0.6 MPa

• Second Lamination: Mechanical mold temperature 150°C - 190°C, time 8 - 25 seconds, pressure 0.3 - 0.6 MPa

As a professional manufacturer integrating R&D, production, and sales of high-polymer hot-melt adhesive materials, Tunsing consistently safeguards clients with high-standard quality control and a comprehensive testing system:

• Precision Testing and Quality Assurance: Operates an in-house standard laboratory equipped with DSC thermal analyzers and rotational rheometers to rigorously monitor melting points, viscosity, and moduli across every production batch.

• Flexible Customization and Rapid Response: Supports custom slitting for various thicknesses (0.05mm - 0.15mm) and widths (5mm - 1480mm) to meet personalized client requirements.

• Factory-Direct Supply and Supply Chain Support: Factory direct sales eliminate intermediate links, providing global clients with highly competitive pricing and stable spot inventory supply capacity.
