Features
nomacorc® is a co-extruded cork for quiet wines, very elastic formed by polymeres, with medium density and chemically motionless.
-
It does not produce bad flavours, it doesn't break and it doesn't desintegrate.
-
Solid insertions and clean process.
-
Long term excellent bottle sealing , with no leaks.
-
Storage can be faced up or down after 24 hours bottled.
-
Traditional appearance and sensation.
-
Smooth and calm drawing.
-
Inorganic materiales unable to lodge TCA.
Foam- How to make a good foam?
A constant and controlled casting temperature.
Constant and controlled pressure.
A constant pore size and density.
Foam co-extrusion (ex.: nomacorc)
Nomacorc uses a two phase co-extrusion process.
The temperature and pressure are constant during the process.
The controlled growth of the cells have as a result a foam with its cells distributed evenly.
The sides and the size of the cells are even and predictable.
It easens the use of different types of materials, both for the outer layer as for the nucleus.
The process creates a protection for the controlled O2 evaporation.
The tops offer the closest behaviour possible to a traditional cork without getting contaminated with TCA, and without producing an incontrolled oxidation.

Thermic processing cycle of temperature changes, from hot to cold.
Great pressure variations ( included inside a small batch).
As a result: great variations in cell dispersion and size.
A foam that looks like “gruyere” cheese.
Limited options in material selection to improve the features performance.
The process is NOT constant in the O2 evaporation protection.
There is NO guarantee of protection in presence of incontrolled oxidation.
Extraction strength is higher.
