Applicable Processes
‑Extrusion Molding: Commonly used for films, sheets and wire‑cable sheaths. ‑Injection Molding: For toys, automotive parts and household‑appliance components. ‑Blow Molding: For hollow articles. ‑Foaming Molding: For foamed products such as shoe soles and padding materials. ‑Hot‑melt Processing: Suitable for preparation of adhesives and sealants. ‑Compression Molding, Structural Foam Molding and other processes.
Processing Characteristics
Drying: Drying is recommended before processing if the material absorbs moisture, to avoid bubbles or silver streaks in finished products.
Processing Temperature: It is critical for EVA processing. Melt temperature is generally recommended not to exceed 230°C. EVA resin has low thermal‑decomposition temperature; excessive temperature will easily cause material degradation.
Mold Temperature: Relatively low mold temperature is generally recommended.
Equipment Selection: Conventional thermoplastic‑processing equipment can be adopted, including ordinary extruders designed for polyethylene processing.
Cooling: Products usually require rapid cooling for setting.
