    General 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.  Less than 1.6 €/kg or 0.9 $/lbs
    2.  1.6 - 4 €/kg or 0.9 to 2.2 $/lbs
    3.  3 to 11 €/kg or 1.6-6 $/lbs
    4.  10 to 25 €/kg or 5.5 to 13.6 $/lbs
    5.  More than 25 €/kg or 13.6$/lbs
