EVA Yangzi‑BASF V5110J
EVA Yangzi‑BASF V5110J
Product Introduction EVA Yangzi‑BASF V5110J is a versatile ethylene‑vinyl‑acetate copolymer resin. It features excellent flexibility, aging resistance, chemical stability, high transparency, good surface gloss and compatibility with multiple processing methods including injection molding, extrusion and foaming, covering a wide range of applications.
Main Applications
Foamed Products ‑Shoe materials: mid‑soles for sports shoes, soles and inner components for slippers and sandals to achieve lightweight, soft and cushioning performance. ‑Padding materials: sound‑insulating boards, gymnastics mats and sealing gaskets.
Wire and Cable: Insulation and sheath layers for wires and cables, suitable for working conditions requiring weather resistance and chemical resistance.
Films and Hoses ‑Films: packaging films and agricultural greenhouse films. ‑Hoses: potable‑water delivery hoses and industrial drainage hoses by virtue of good flexibility and chemical resistance.
Industrial Injection‑molded Parts: Injection‑molded products such as industrial components and toys.

Processing Technology
| Processing Method | Key Parameter | Recommended Range / Description | Important Reminder |
|---|---|---|---|
| Injection Molding | Barrel Temperature | 165‑180℃, preferably not exceeding 200℃ | Strict temperature control; temperature is recommended not higher than 180℃ to prevent resin degradation. |
| Injection Pressure | Moderate, avoid excessively high or low value | Insufficient pressure causes molding defects; excessive pressure imparts poor product appearance. | |
| Mold Temperature | Matched with barrel temperature | Prevent product shrinkage and deformation. | |
| Extrusion Molding | Processing Temperature | 120‑200℃ | Applied to extruded products such as pipes, sheets and cable sheaths. |
| Foaming Molding | Processing Temperature | Adjust according to foaming agent type and product requirements | Excessively high temperature will trigger premature decomposition of foaming agent and resin degradation; the dosage of foaming agent shall be precisely adjusted. |
