Protak Group - Manufacturers of adhesives and suppliers of furniture
fitting to the manufacturing industry.
Protak was established in 1988 with a commitment to service and
excellence. This has led to steady growth, initiating rapid expansion,
to the point where Protak are one of only a small number of adhesive
manufacturers producing both water based and hot melt adhesives in the
UK.
The range of adhesives were, in the early years, imported from Europe.
In 1995 production was set up in the UK. During the first year after
the dispersion plant (Factory No1) was formed, the sale of these
products doubled which led to the decision two years later to set up
the hot melt unit (Factory No2). This new factory development utilizes
some of the most modern production techniques in Europe, enabling
Protak to supply exactly and promptly a complete range of industrial
adhesives.
Quality has always been of paramount importance to us, but it has also
been the flexibility in our manufacturing process that has enabled
Protak to fine-tune our products, so that each customer can receive
precisely the type of product required.
Housed in Factory No.1 is is our purpose built laboratory. Having
achieved ISO 9002, the laboratory services the research, development
and the quality control requirements of our adhesives. It is
impressively equipped and includes rotary viscometers, to measure
viscosities, thermocell units for viscosities at high temperatures,
and ring and ball apparatus for testing melting points. There are two
ovens, one for low temperature work, the other a muffle furnace for
ash value testing. Determinations of this type call for precise
weighing so there are two electronic balances ~ one to an accuracy of
0.001 gm, the other to high precision weighing down to 0.0001 gm. The
ovens are also used for ageing, creep, peel and other tests on glues.
Factory No.1 also houses the dispersion plant which comprises of two
complete units, one for vinyl emulsion adhesives and the second for
polyurethane dispersions. To cope with waterborne products, the entire
plant is made from stainless steel, including the valves, pumps,
filters and begins with vertical storage tanks for the base emulsions
with connections for road tankers. The daily output of finished
product in a single shift, is around 5000 litres.
Factory No.2 produces hot melt adhesives. The old methods of making
hot melt products ~ dictated by the supply of raw materials in chopped
ribbon form ~ entailed blending in a heated Z-blade mixer followed by
discharging onto a chill table and cutting into granules on a kibbler.
This has been superseded by a modern method (Protak being one of only
two adhesive installations in the UK using this system) which is
faster and ensures better blending.
With the raw materials supplied in the form of powders, fine granuals
or pastes, the procedure now is to blend them in a single mixer, then
transfer the mix to a screw extruder which heats the powder blend to
melting point and forces it through the extrusion chamber ~ thus
ensuring intimate mixing. Finally, the hot mix is chilled and passed
through a pelletising head which forms it into round pellets.
A typical production line requires two operators which can produce
about 3000kg per single shift or something approaching 1000 tonnes per
year. The compact plant is easy to run and is ideal for making trial
batches of only 200-300kg as well as for large scale production.
The range of adhesives we can offer covers many different fields of
industry and comprise some 200 formulations,with at least 50% of these
in regular use.
