Driving Innovation in Seamless Bonding & Industrial Lamination: Tunsing Plastic Releases Technical Data Solution for DS0012T Copolyester Hot Melt Adhesive Film
【Company News】 Recently, Shenzhen Tunsing Plastic Products Co., Ltd. officially released the updated Technical Data Sheet (TDS V1.2) for its high-performance copolyester hot melt adhesive film—DS0012T.
Engineered specifically for seamless garments, footwear accessories, luggage, reflective materials, and PC/PVC composite materials, DS0012T provides global industrial clients with a highly stable, eco-friendly, and durable bonding solution backed by rigorous thermodynamic and rheological analysis.
1. Key Features & Industrial Applications
DS0012T is a thermoplastic film-like adhesive composed of premium copolyester with a glassine release paper backing. Featuring a milky white, semi-transparent appearance, it allows for repeated heating, plasticization, and solid bonding.
Superior Substrate Adhesion & Washability
-
Broad Substrate Compatibility: Delivers outstanding peel strength and adhesion to textiles, PVC, and PC materials.
-
Excellent Washability: Built to withstand $40^\circ\text{C}$ water washing and offers exceptional dry-cleaning resistance, ensuring a long service life for finished products.
Wide Range of Applications
-
Garments & Footwear: Seamless clothing lamination, apparel accessories, shoe uppers, and sole reinforcement.
-
Bags & Luggage: Lamination and structural reinforcement for leather and fabric bags.
-
Reflective Materials & Embroidery: Reflective badges, embroidered patches, heat transfer emblems, and handicraft bonding.
-
Electronics & Plastics: Thermal lamination for PC and PVC plastic sheets and films.
2. Technical Specifications & Product Parameters
Tunsing's engineering team has defined precise physical and flow characteristics for DS0012T to ensure high-precision processing:
| Parameter | Specification | Testing Standard / Remark |
|---|---|---|
| Composition | Copolyester | Structure: Release Paper + Adhesive Film |
| Color | Milky white, semi-transparent | Supported by Glassine Release Paper |
| Density (Proportion) | $1.15 \pm 0.02 \text{ g/cm}^3$ | — |
| Conventional Thickness | 0.06mm, 0.09mm | Customizable |
| Width Range | 5mm – 1480mm | Conventional Roll Width: 1000mm |
| Melt Flow Index (MI) | $20 \pm 10 \text{ cm}^3/10\text{mins}$ | ASTM D1238-04 |
| Melting Point (DSC) | $85\text{--}115^\circ\text{C}$ | ISO 11357 (Peak Temp: ~$105.4^\circ\text{C}$) |
| Activation Temperature | $108\text{--}153^\circ\text{C}$ | Tunsing Standard |
3. In-Depth Thermal & Rheological Analysis
To assist manufacturers in accurately setting mold temperatures and processing parameters, Tunsing R&D conducted advanced testing using Netzsch DSC 214 and Anton Paar rotational rheometer equipment:
-
Differential Scanning Calorimetry (DSC):
-
Glass Transition Temperature ($T_g$): Approximately $8.1^\circ\text{C}$.
-
Endothermic Melting Peak: Located at $105.4^\circ\text{C}$ with a melting range of $85\text{--}115^\circ\text{C}$, demonstrating strong thermal stability during elevated processing temperatures.
-
-
Viscoelastic Transition Point:
-
Evaluated by identifying the crossover point of storage modulus ($G'$) and loss modulus ($G''$), marking the transition from a viscoelastic solid to a viscoelastic fluid.
-
Testing charts indicate that the transition temperature of DS0012T is approximately $113.1^\circ\text{C}$. This higher transition point ensures optimal melt viscosity during hot-pressing, effectively preventing glue seepage and satisfying high-heat bonding requirements.
-
4. Recommended Lamination Parameters
To achieve optimal peel strength and lamination quality, Tunsing recommends the following parameters for automated hot-press machinery:
| Processing Stage | Mechanical Mold Temperature | Time | Pressure |
|---|---|---|---|
| First Lamination | $140\text{--}180^\circ\text{C}$ | 5 – 15 seconds | 0.3 – 0.6 MPa |
| Second Lamination | $150\text{--}190^\circ\text{C}$ | 8 – 25 seconds | 0.3 – 0.6 MPa |
Note: Actual bonding results are influenced by substrate properties, pressure uniformity, and mold flatness. Trial testing is recommended prior to mass production.
