<input ... > <input ... > | EVA - Ethylene Vinyl Acetate | | | Cost Index*: 1 | | Strengths | Limitations |
- Highly flexible
, even at low temperatures (-25°C)
- Higly compatible with a lot of elastomers, TP and other materials (SBr, EPDM, TPE, PE, PVC, asphaltum ...)
- Better tear resistance than LDPE
- Excellent resistance to environmental stress cracking
- FDA compliant
- Good UV and ozone resistance
| - Poor heat resistance
- Reduced barrier properties compared to LDPE
- Attacked by polar solvents, hydrocarbons, oxydants and strong acids
- Reduced creep resistance, compared to LDPE

| ProcessabilityGeneral information | These resins are not hygroscopic and may be used as received without need for drying. At temperatures above 220ºC, EVA resins can evolve toxic fumes.
| Injection molding | Experience has shown screws normally used for injection molding of low density polyethylene to be satisfactory. Melt temperature : 150-200°C Mold temperature : 15-40ºC
| Extrusion | A three-zone screw with a total L/D ratio of at least 20 is recommended. Melt temperature is, generally, in the overall range of 95-205ºC . The melt temperature depends upon the melt index of the resin, the % vinyl acetate and the part configuration. | | *Cost Index | 1.
