Shenzhen Tunsing Releases Model Selection Guide for Flagship DS9164 and DS9166 Hot Melt Adhesive Films

Here is the English translation of the news release and product selection guide, complete with references to the technical datasheets:

[Shenzhen, China] As modern textile, apparel, and composite processing industries demand increasingly higher standards for seamless lamination, Shenzhen Tunsing Plastic Products Co., Ltd.—a leading provider of adhesive solutions—has officially released a comprehensive comparison and selection guide for its two flagship polyurethane-based hot melt adhesive films: DS9164 and DS9166.

Both products are crafted from high-grade polyurethane, supported by Glassine release paper, and designed to allow repeated heating and plasticization for durable bonding. They are widely used in seamless bonding applications across clothing, embroidery, footwear, luggage, handbags, and sporting goods. To help global manufacturers select the ideal film for specific tactile requirements, processing temperatures, and substrate properties, the Tunsing engineering team has provided a detailed technical evaluation comparing both models.

The table below summarizes the physical and thermodynamic differences between DS9164 and DS9166:

Based on empirical testing by Tunsing Laboratory, manufacturers can determine the right film according to three primary operational criteria:

• Rationale: DS9166 features a Shore hardness of 60 Shore A (compared to 96 Shore A for DS9164), delivering an exceptionally soft tactile feel and excellent elasticity.

• Recommended Applications: Seamless underwear, high-stretch sportswear, lightweight fabrics, and premium apparel where comfort is paramount.

• Rationale: DS9164 boasts a glass transition temperature (Tg) down to -45°C (peak -45.4°C), ensuring strong flexibility in freezing conditions. Furthermore, its activation temperature starts as low as 90°C, with a rheometer solid-to-fluid transition at 97.1°C.

• Recommended Applications: Outdoor cold-weather gear, ski apparel, rigid plastic substrates (PC, ABS), and heavy-duty footwear or bags.

• High Optical Clarity: Select DS9166 for transparent film finish.

• Edge Flow Control: Select DS9164 for low-flow properties that keep bonding edges neat and free from excess adhesive bleed.

Shenzhen Tunsing provides full dimension customization for both DS9164 and DS9166 to accommodate automated production setups:

• Standard Thicknesses: 0.05 mm, 0.08 mm, and 0.10 mm (Custom range: 0.03 - 0.15 mm).

• Roll Width: 1380 mm standard width (Slitting options available from 5 mm to 1480 mm).

• Standard Roll Length: 100 yards/roll.
