GRANULATED
CORK
The
granulated cork is obtained through milling and grinding operations: shavings
and other wastes.
This
product is completely natural and does not involve any risks for the
environment, it can be used in a wide range of applications, according with its
specifications, and it is the base for all the agglomerated cork industry.
We
pawn in the rigorous selection and quality control of the raw material, in
order to obtain granulated cork of high quality.
In
its natural state, can be used as an incubator substance for certain types of
packages, like the ones that are used in the fruits and fragile articles; it
can also be used in the building construction and automobile industry, due to
its excellent properties of acoustic, as well as thermo and anti-vibration
insulation.
AGGLOMERATED
CORKS
We
are also producers of agglomerated corks, obtained by agglutinating granulated
cork (after a thermo-mechanical treatment) with food binders and additives,
using the method of extrusion, with calibres between 31x17 mm and 50x30 mm.
SOIGA's
corks can be commercialised without treatment or, optionally, with the
following:
Peroxide washing
(H2O2)
Surface coat with
CAF
Surface coat with
Silicone
Surface
coat with Paraffin
The corks
can also be marked (fire branding), according with the clients' request. Each
order is followed by a Quality Certificate.
The
corks may not have any kind of finishing or, may have the following options:
-
Chamfered
-
Polish on the
tops
-
Coloured
To
support our diversification policy we produce 1+1 corks (natural cork disks
that are glued on the tops of the body). We can also supply tapered
corks with diversified sizes for the most different usages.

General recommendation
1.
To choose the size of the stopper, it is very import to pay attention to
following items:
The
type of wine;
Model
of the bottle;
Conservation
time of the wine;
Others.
2.
The cork stoppers must be stored in
dry spaces. In spaces free of odours and must be keep faraway from spaces where
wood dealt with chlorinated products exist. Shall
note be stored also, nearby the susceptible products to cause microbiological
and chemical contamination.
3.
Must respect corrects bottling norms, namely, to respect the maximum pressing
of the maxillas which can not exceed 5 times less then the diameter of the
stoppers.
4.
Bags must be shed into the corking machine directly, for hygienic reasons.
The
compression of the corking machine does not to be made to values superior than
33% of the diameter of the stopper and should be 1,5 to 2 mm less than the
inside diameter of the bottle neck.
5.
A space between the agglomerated cork stopper and the wine of minimum 15 mm
(bottles of 75 cl). For the sparkling wines, this value must be respected.
6.
Waiting about 30 minutes before lying down the bottle.
7.
The remainder stoppers kept in the corking machine must be replaced in a closed
bag but they must be used with brevity.
8.
The transport of wine should be done in up right position.
AGGLOMERATED
CORK
COVERINGS
Developing
a cork flooring system of high quality is, since 1995, one of
SOIGA's major purposes.
To benefit
from the well-known cork performances, such as durability, impact resistance,
shock absorbing and sound isolating,
SOIGA
developed a wide range of products.
The agglomerated obtained through granulated cork is compressed with special binders, making the SOICORK material a natural and ecologically acceptable product.
In
order to cover a wide range of applications, SOICORK material is divided
in 3 types of densities:
High
Medium
Low
For the finishing surface we must point out the following:
Glossy
varnish
Matte
varnish
Wax
Wax-oil
Coloured
varnish
SOICORK material obeys to the Portuguese
standards and all the orders leave SOIGA with a quality
certificate issued by our laboratory.
SOIGA's coverings can
be commercialised as:
Parquet
Decoratives
Cork veneer
Soft
Floating
Skirting
boards
Cork Wall Tiles
(With
or without surface finishing)
The
parquet and the cork decoratives can have the following
dimensions (mm):
600 x
300 x e
300 x 300 x
e
The maximum dimensions ARE 945X635 mm.
The
cork veneers are made with two agglomerated cork sheets: one base and
one decorative sheet. The bases are
produced using the same method as the parquet, but are not commercialised in
the same way, the purpose is binding them with decorative sheets, in order to
make the cork veneers. The cork veneers can be produced with different
dimensions, according to the clients' request (it happens the same with the
parquet and with the cork decoratives).
The
soft material produced can have the maximum dimensions of 945x635 mm
and in any thickness . The soft can be used as "underlay", it has
many applications for the shoes industry (ex: insoles), for the production of
several objects (ex.: fishing rod, skis, cricket balls, ...).
The
cork floating is used as floor covering and its main advantage is the
easy application and ideal renovation.
This kind of
flooring isn't glued or nailed to the floor; its union is guaranteed by a
'tongue and groove' system, developed by our company.
SOIGA's floating can
have the following dimensions
(mm):
900 x 300 x
9.6
900 x 300 x
10.8
This
material has 3 layers:
Top
layer:
'Standard' parquet or decorative or cork
veneer
Middle
layer: HDF
Inferior
layer: Soft
(underlayment)
The
HDF used has low emission levels of formaldehyde and has a high resistance to
flexion; it can bear heavy weights and repetitive impacts.
The
skirting boards made by SOIGA can have several dimensions, according to
our clients' specifications. However, the most usual dimensions are (mm):
900 x 70 x
5
900 x 70 x
8
The
cork wall tiles can be cut in tiles or sheets with 3mm
(or similar thickness). Usually the agglomerated cork veneered
is glued in an agglomerated cork backing with higher
density.
Considering
our diversification policy, our company can
also supply the shoe industry (soles,
heels,...). We are also producing rubber cork and
gifts, but... FIND OUT MORE IN OUR ONLINE CATALOG
Cork
gifts can be used to stimulate children imagination, being a
funny and colourful way to decorate walls, doing manual
works with an ecological product and environment
friend.
For
the production of our agglomerated coverings, we rely upon sophisticated
equipment and daily control of technical personnel, duly specialized, which
assures a prestige quality.
