Ethylene Acetate Sheet

Additional Details

We engaged in supplying Ethylene Vinyl Acetate

Density 0.92 – 0.94 g/cm^3

Gamma radiation resistance Fair

UV light resistance Poor

Max continuous Service temperature 45 – 70 C

Min continuous Service temperature 60 C

Sterilization insulation (Repeated) Poor

These resins are not hygroscopic and may be used as received without need for drying.

At temperature above 220 C, 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 – 40 C

Extrusion :-

A three- zone screw with a total L/D ratio of at lease 20 is recommended.

Melt temperature is, generally, in the overall range of 95 – 205 C.

The melt temperature depends upon the melt index of the resin, the % vinyl acetate and the part configuration

Strengths

    Highly flexible, even at low temperature (-25 C)

    Highly compatible with a lot elastomers, TP and other materials (SBr, EPDM, TDE, PE, PVC, asphaltum…..)

    Better tear resistance than LDPE

    Excellent resistance to environmental stress cracking FDA compliant

    Good UV and ozone resistance

Limitations

    Poor heat resistance

    Reduced barrier properties compared to LDPE.

    Attacked by polar solvents, hydrocarbons, oxidants and strong acids

    Reduced creep resistance, compared to LDPE
