Copolyamide Pellets For Hot Melt Filament Extrusion Virgin CoPA Granules For Hot Melt Yarn Production

• ✅ Virgin raw material, consistent quality, low impurity, less broken filament during customer’s high-speed extrusion
• ✅ Stable melt viscosity, excellent spinnability, suitable for customers’ long-run continuous hot melt yarn production
• ✅ Outstanding adhesion strength of final hot melt yarn to polyamide/nylon substrates, good flexibility after bonding
• ✅ Moderate melting point range, adjustable formulation to fit different heat press process requirements of finished yarn
• ✅ Solvent-free, eco-friendly, no volatile emission, meets textile and automotive environmental standards
• ✅ Good low-temperature toughness; composite parts bonded by resulting hot melt yarn will not turn brittle in cold environment
• ✅ Uniform pellet dimension, smooth feeding for automatic extruder system, no hopper bridging

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).

Bulk MOQ normally 1000KG. Small test sample (1~2KG) is available for lab extrusion and trial production.
