Processing Technology
| Processing Method | Key Parameter | Recommended Range / Description | Important Reminder |
|---|---|---|---|
| Hot‑melt Adhesive Processing | Melt‑mixing Temperature | 150‑180℃ normally | Strict temperature control! Avoid long‑time high‑temperature residence (generally ≤4 h), to prevent oxidative degradation (yellowing, viscosity drift, pungent odor). |
| Application Temperature | Adjust by formula, normally 160‑190℃ | Temperature shall guarantee good flowability and wettability of hot‑melt adhesive, meanwhile avoid overheating. | |
| Equipment | Sealed melt‑mixing equipment (reactor) with inert gas (nitrogen) protection preferred | Minimize air contact, critical for stable adhesive performance. |
