Set of plastic samples
For differentiating the physical and chemical
characteristics of altered natural substances
and plastics. The set consists of a storage tray
with approx. 50 samples made of 8 different
types of plastic.
Dimensions: 300 x 300 x 50 mm
Weight: 1.0 kg
664 703
Miniature plastic press
A small-scale press used to manufacture plastic
laminates. The press may be used to make
metal-coated boards from phenol resin plastics,
similar to those used as printed circuit
boards in the electronics industry.

DIN A4 volume of transparencies with
explanations and master copies for students
work-sheets.
· 18 three coloured basis transparencies
without text which illustrate the technologies
and production methods for the manufacture
of plastics.
664 700
Reel
For winding up synthetic fibres produced by
precipitation polymerization, interfacial polymerization
or produced in a precipitation bath.
The spool can be attached to a stand without
difficulty.

· 18 Overlays with text giving solutions.
· 18 Master copies
for students work-sheets.
· 2 Transparencies "Polymerisation,
Polycondensation and Polyaddition".
· 2 Transparencies "The Chemical Structure of
the most important Plastics".
special topics
Plastics have influenced and changed our lives
and environment considerably. These materials,
once described as “substitute materials” and
“disposable materials”, have acquired considerable
influence on modern technical processes,
which would be inconceivable or impossible
without these plastics. Therefore, it is no surprise
that the topic “plastics” is an integral part of
modern, environment-related chemistry
instruction. Chemistry instruction in the Federal
Republic of Germany has adapted its curriculum
to incorporate the chemistry of plastics.
664 701
Spinning nozzle
For the production of synthetic fibres by means
of precipitation reaction. The substance is filled
into the container and pressed through the
nozzle into the precipitation bath. Complete
set, comprising material container, nozzle plate
and seal.
Length: 150 mm
Diameter: 20 mm
Weight: 0.1 kg

Casting mould
664 701
Negative mould for preparing a plastic model.
This mould can, for example, be used to
produce samples of artificial glass from
methacrylic acid methyl ester polymers.
664 705
Plastic processing and vacuum forming device
Combination device used to process plastics
(e.g. cutting, bevelling, bending, turning and
deep drawing). The compact design keeps
material consumption to a minimum. It is
possible nonetheless to cut expanded
polystyrene ("Styrofoam") parts up to 190 mm
high and 370 mm wide, for instance. When
bevelling thermoplastics, parts up to 190 mm
long and 3 mm thick may be used. The heating
zone permits flexibility in bending, allowing for
free-hand shaping. The unit also makes it
possible to turn mouldings and balls. The
vacuum moulding unit included in this set
makes it possible to deep draw polystyrene
panels up to 1 mm thick.
Dimensions: 720 x 410 x 610 mm
Weight: 10.4 kg
