DS2405 vs. DS002: A Strategic Guide to Selecting PA Films Based on Washability and Processing Efficiency hot melt film
2026/04/15
SHENZHEN, China – April 23, 2024 – Shenzhen Tunsing Plastic Products Co., Ltd., a global leader in thermoplastic adhesive technology, is proud to announce the latest technical advancements for its premier Copolyamide (PA) hot melt adhesive film series. With the release of updated Technical Data Sheets (V1.4 for DS2405 and V1.3 for DS002), Tunsing provides garment, footwear, and industrial manufacturers with unprecedented data transparency and bonding precision.
Both the DS2405 and DS002 are thermoplastic hot melt films supported by high-quality glassine release paper, designed for repeated heating and plasticization. While both are engineered for superior adhesion to textiles, clothing, embroidery, and luggage, they offer distinct advantages tailored to specific manufacturing requirements.
The DS2405 is the definitive choice for products requiring maximum resilience against environmental factors and rigorous cleaning cycles.
-
Ultimate Wash Resistance: Specifically engineered to withstand dry cleaning and high-temperature washing at 60°C.
-
Cold-Weather Reliability: Features a low glass transition temperature (Tg) of -5.4°C, ensuring material toughness and preventing brittleness in freezing environments.
-
Stable Processing: Operates within a melting range of 100-120°C, providing a consistent bonding window for technical textiles.
The DS002 is optimized for high-speed production lines and general-purpose textile bonding where flow and penetration are paramount.
-
Enhanced Flow Dynamics: Boasts a higher Melt Flow Index (45 ± 25 cm³/10min) and a lower transition temperature of 94.1°C, allowing the adhesive to penetrate fibers rapidly.
-
Standard Durability: Provides reliable resistance to dry cleaning and home laundering at 40°C.
-
Invisible Aesthetics: Features a unique pale blue transparent finish, maintaining the visual integrity of premium substrates.
