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
