Precision Control & Low Flow: Tunsing Officially Releases DS6194 High-Performance Hot Melt Adhesive Film

SHENZHEN, March 5, 2025 —— Shenzhen Tunsing Plastic Products Co., Ltd., a leading global manufacturer of eco-friendly bonding materials, today announced the launch of its next-generation hot melt adhesive film product: DS6194. As an advanced upgrade to its product lineup, DS6194 delivers a unique low flow value processing characteristic, excellent cold resistance, and a highly customizable range of specifications, making it a powerful new tool for precision manufacturing in the apparel and composite materials sectors.

DS6194 is a thermoplastic, film-like hot melt adhesive derived from Polyurethane. Supplied with high-quality Glassine release paper, it supports repeated heating and plasticization for bonding. The product's formulation has been deeply optimized to offer several core advantages:

• Controlled Low Flow Value: It features a low flow value during thermal lamination, ensuring that the adhesive flow is highly controlled to prevent overflow from marring the appearance of substrates, providing greater processing tolerance.

• Excellent Material Compatibility: Delivers outstanding adhesion to textiles, TPU, PVC, PC, and ABS.

• Superb Cold Resistance: An exceptionally low glass transition temperature ensures that the film maintains outstanding crack prevention and flexible toughness even in freezing environments.

• Versatile Applications: It is widely used for bonding materials in clothing, embroidery, footwear, bags, handbags, toys, hats, and sporting goods.

To meet the stringent requirements of manufacturing enterprises for digital processing, flexible customization, and precise machinery matching, Tunsing Laboratory has comprehensively analyzed the thermodynamic and physical characteristics of DS6194 across recognized standards (such as GB/T, ASTM, and ISO):

Tested via a Netzsch DSC 214 instrument at a heating rate of 10°C/min under a nitrogen atmosphere, along with an Anton Paar rotational rheometer, DS6194 exhibits highly stable thermal performance:

• Activation Temperature Range: 90-150°C.

• DSC Thermal Behavior: A significant endothermic effect is observed near -45.4°C, identifying the precise glass transition temperature of the film. Meanwhile, a clear melting peak appears near 48.2°C.

• Viscoelastic Fluid Transition Point: Dynamic mechanical parallel plate testing shows that the storage modulus and loss modulus intersect at approximately 97.1°C. Above this temperature, the material transitions from a viscoelastic solid to a viscoelastic fluid, allowing it to thoroughly wet out and bond to substrates.

DS6194 delivers exceptional bonding strength under specified PU cloth and PC lamination tests. To assist manufacturers in achieving optimal peel strength, Tunsing recommends the following standard processing guidelines:

• First Lamination:

  • Mechanical Mold Temperature: 130°C-180°C

  • Time: 5-15 seconds

  • Pressure: 0.3-0.6mpa

• Second Lamination:

  • Mechanical Mold Temperature: 140°C-180°C

  • Time: 8-25 seconds

  • Pressure: 0.3-0.6mpa

Important Notice: Actual bonding conditions will vary depending on the specific machinery and materials used, as the conditions stated here are basic baselines. The bonding temperature must be close to the temperature set by the machine, the pressure must be uniform, and the mold and press rolls must be flat. Manufacturers must conduct detailed verification prior to volume production to establish the most ideal conditions for their unique applications.

Shenzhen Tunsing Plastic Products Co., Ltd. is dedicated to the R&D and manufacturing of high-performance, eco-friendly hot melt adhesive films. Grounded in rigorous scientific data and driven by quality, Tunsing provides reliable, efficient, and comprehensive bonding solutions to global industries.
