Plastic materials
The environmental aspects are in the
foreground at the choice of raw
materials. Provided the technical
conditions are met, the choice falls
on a raw material that is safe for the
environment. Recyclable polycarbon-
ate (PC) and acrylic butadien sty-
rene (ABS) are the raw materials
that Ensto has chosen for its en-
closures.
Polycarbonate (PC)
Polycarbonate, an excellent mate-
rial for instrument housing, is an
amorphous thermoplastic material
with high temperature endurance
and good technical properties. Poly-
carbonate is suitable for use indoor
as well as outdoor. It is weather re-
sistant, it has good electrical fea-
tures and is selfextinguishing.
Acrylic butadien styrene
(ABS)
ABS is an amourphous thermoplas-
tic material with good mechanical
properties and high chemical resis-
tance. ABS is a good choice for in-
door use also for severe surround-
ings.
Machining of PC and
ABS
Both materials are easy to machine
with normal hand tools. They can be
painted with suitable lacquers, and
they can be welved with ultrasonic
equipment.

Maintenance of PC and
ABS enclosures
Water and mild soap are enough for
cleaning the enclosures. Solvents
should not be used. No special
maintenance is needed.
