Copolyamide Pellets For Hot Melt Filament For Flyknit Shoe Vamp Bonding CoPA Granules

• ✅ Custom formulation targeting flyknit vamp filament spinning, good melt elasticity to mitigate filament thinning and breakage at high spinning speed
• ✅ Narrow melt viscosity window, stable output consistency for continuous multi-hour extrusion
• ✅ Excellent interfacial adhesion on nylon-based flyknit fabrics, delivers reliable peel strength after heat pressing
• ✅ Adjustable activation temperature, compatible with low-to-medium heat molding commonly adopted by shoe factories
• ✅ Bonded flyknit vamp retains softness and breathability, no rigid hardening after repeated heat cycles
• ✅ Low odor, non-toxic and solvent-free, meets global footwear eco compliance standards
• ✅ Well-screened pellet geometry, good free-flow property to avoid feeding interruption in extruder hopper

1. The surface should be clean, dry and free from solvent or grease. Low surface/environment temperature of the substrate may cause early adhesive condensation, open time shortening and even adhesive falling off. If necessary, preheat the adhesive.
2. Operate above 140°C with 1-3 kg pressure to the substrate for 10-20 seconds to complete the bonding.
3. After bonding, it will achieve the final strength after complete crystallization at room temperature (25°C).

Yes. It is optimized for hot melt filament extrusion. Please refer to our TDS for recommended drying protocol and barrel temperature profile before formal trial spinning.
