EVA Lotte Chemical VA900 Resin
EVA Lotte Chemical VA900 Resin
Material Introduction: EVA Lotte Chemical VA900 is EVA resin with VA content 28% and melt index up to 150 g/10min. High melt index delivers excellent melt flowability. It features outstanding adhesiveness, flexibility, oxidation resistance and environmental‑friendly performance, especially suitable for hot‑melt adhesive fields requiring rapid wetting and bonding.
Main Applications
Hot‑melt adhesives: Core application. ‑Book‑binding hot‑melt adhesive: perfect binding for books and magazines. ‑Packaging hot‑melt adhesive: carton sealing, food packaging, assembly of disposable articles. ‑Other bonding applications: furniture edge‑banding etc.

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. |
