Tunsing Releases DS6601 High-Performance Hot Melt Adhesive Film: A Professional-Grade Solution for Superior Bonding
[SHENZHEN, July 31, 2026] — Shenzhen Tunsing Plastic Products Co., Ltd., a leading manufacturer of adhesive materials, has officially released its core technical product: DS6601 Thermoplastic Hot Melt Adhesive Film. Formulated with polyurethane synthetic modification and supported by a release paper backing, the film features exceptional re-heatable plasticizing properties, designed to deliver high-reliability bonding for clothing, embroidery, luggage, handbags, and sports goods.
Core Performance & Technical Specifications
DS6601 hot melt adhesive film demonstrates top-tier professional standards across its physical properties and processing parameters:
1.
Physical Characteristics
-
Appearance & Density: Transparent in color, with a density of $1.18 \pm 0.02\text{ g/cm}^3$.
-
Hardness: Rated at $88 \pm 3\text{ Shore A}$, offering a balanced mix of flexibility and structural strength.
-
Melt Flow Index (MFI): $60 \pm 10\text{ cm}^3/10\text{min}$ (based on ASTM D1238-04 test standards).
-
Thermal Properties:
-
Melting Range: $35^\circ\text{C} - 55^\circ\text{C}$ (ISO 11357).
-
Glass Transition Temperature ($T_g$): $-35 \pm 8^\circ\text{C}$ (GB/T 19466.2-2004) , with DSC analysis confirming an endothermic $T_g$ event down to $-30.3^\circ\text{C}$ for excellent cold resistance.
-
Activation Temperature: $85^\circ\text{C} - 105^\circ\text{C}$.
-
Viscoelastic Transition Temperature: Rotational rheometer testing shows the crossover point between storage modulus and loss modulus occurs at approximately $96.1^\circ\text{C}$, ensuring controllable flow and adhesion under heat.
-
2.
Specifications & Structure
-
Release Protection: Utilizes Glassine Release Paper with a thickness range of $0.03\text{mm} - 0.15\text{mm}$.
-
Dimensions: Available in conventional film thicknesses of $0.05\text{mm}$, $0.10\text{mm}$, and $0.15\text{mm}$ ; configurable width ranges from $5\text{mm}$ to $1580\text{mm}$ (conventional width $1380\text{mm}$) ; finished roll size is $1380\text{mm} \times 100\text{ yards/roll}$.
