Empowering Efficient Bonding in Textiles & Composites: Tunsing Plastic Releases Latest Technical Solutions for DS001TS and DS0012T Copolyester Hot Melt Adhesive Films
【Executive Summary】 Shenzhen Tunsing Plastic Products Co., Ltd. has officially updated and released the latest Technical Data Sheets (TDS) for its core copolyester hot melt adhesive films—DS001TS and DS0012T. Specially engineered for seamless garments, footwear, reflective materials, bags, and PC/PVC composite lamination, both products deliver outstanding washability, dry-clean resistance, and precise thermodynamic performance, offering global clients high-standard thermoplastic bonding solutions.
1. Product Overview & Key Benefits
Both DS001TS and DS0012T are thermoplastic copolyester hot melt adhesive films supported by a glassine release paper backing. Featuring a milky white, semi-transparent appearance, they allow repeated heating, plasticization, and solid bonding.
Excellent Substrate Adhesion & Environmental Resistance
- Broad Substrate Compatibility: Exhibits superior adhesion to textiles, PVC, and PC materials.
- Washing Durability: Capable of withstanding 40°C water washing and offers excellent dry-cleaning resistance.
Diverse Application Fields
Widely applicable across multiple industries:
- Garments & Footwear: Apparel lamination, seamless clothing, footwear uppers, and sole accessories.
- Luggage & Bags: Reinforcement and lamination for various leather and fabric bags.
- Reflective Materials & Embroidery: Reflective badges, embroidered patches, and handicraft bonding.

3. Advanced Thermodynamic & Rheological Analysis
Conducted using Netzsch DSC 214 instruments and Anton Paar rotational rheometers, Tunsing’s laboratory provides in-depth analytical insights:
- Differential Scanning Calorimetry (DSC):
- DS001TS: Shows a glass transition temperature (Tg) around 5.8°C and an endothermic melting peak at 95.1°C.
- DS0012T: Exhibits a Tg around 8.1°C with a melting peak at 105.4°C.
- Viscoelastic Transition Temperature:
- Evaluated by identifying the crossover point of storage modulus (G') and loss modulus (G''), marking the phase change from a viscoelastic solid to a fluid.
- DS001TS reaches its transition point at approximately 78.1°C, whereas DS0012T transitions at 113.1°C, giving manufacturers accurate temperature benchmarks for pre-heating and pressing operations.
4. Recommended Lamination Conditions
To achieve optimal peel strength, the following standard parameters are recommended for automated laminating machinery:
1. DS001TS Recommended Parameters
- First Lamination: Mechanical Mold Temperature 130–160°C, Time 5–15 seconds, Pressure 0.3–0.6 MPa.
- Second Lamination: Mechanical Mold Temperature 130–170°C, Time 8–25 seconds, Pressure 0.3–0.6 MPa.
2. DS0012T Recommended Parameters
- First Lamination: Mechanical Mold Temperature 140–180°C, Time 5–15 seconds, Pressure 0.3–0.6 MPa.
- Second Lamination: Mechanical Mold Temperature 150–190°C, Time 8–25 seconds, Pressure 0.3–0.6 MPa.
Notice: Actual lamination results depend heavily on material characteristics, pressure uniformity, and mold flatness. Detailed trial testing is recommended prior to mass production.
