Extrusion
Using OCEANEX, blown films can be extruded at low temperature and low pressure, increasing the linear output for a lower energy cost.
The semi-matt finish is ideal for printing in fine detail and films require less or no electrical corona treatment.
Chemical consumption is also reduced. The natural frosted colour of the supplement extends and brightens pigments which means that less coloured masterbatch is required to create coloured films.
The CaCo3 dispersed in the film creates a natural anti-blocking property which means that less, or no release agent is required.
Injection Moulding
For injection moulding and thermoforming OCEANEX adds properties typically found by the addition of mineral based fillers. Treated products benefit from lower shrinkage and better structural stiffness and impact resistance.
As with blown films the natural whiteness of OCEANEX allows it to function as a white pigment, helping to reduce and in certain cases completely avoid the addition of expensive coloured masterbatch.
OCEANEX is particularly suited for products such as HDPE bottles and polypropylene caps and closures where loading levels can reach nearly 50%.
