Plastics from GEHR
Founded in 1932 and family-owned ever
since, GEHR Plastics is a leading
worldwide manufacturer of semi-finished
thermoplastics, primarily in rods and
sheets. The headquarters for this
medium-sized company is Mannheim,
located in southwestern Germany. For
25 years GEHR has had an American
subsidiary and production facility near
Philadelphia.
GEHR also operates several sales offices
in France, Italy, PR China and Japan.
GEHR remains committed to
these important principles
Long-term independence
The independence of this third-generation, family-owned company, as well
as its focus on solid, long-term planning
and development remains of essential
importance to us.
Partnership
We view ourselves as a loyal partner
with our customers, and we live the
values of reliability and fairness with
regards to our customers, suppliers and
employees. Correspondingly, our friendly
and competent service is acknowledged
in our industry, assisted by the longstanding personal relationships that exist
between our customers and their longterm contacts here at GEHR. A wide
range of seminars, workshops and
symposiums enhances our service as
well.
Quality leadership
GEHR is certified ISO 9001, and we
continue to strive for excellence in
product quality by generally exceeding
our customers’ requirements. Over time,
our products will receive additional
approvals and certifications, as
exemplified by the recent approval by
the German Water Quality Regulation for
PVC-U.
Versatility
We continue to expand our product
range for extruded rods, sheets, profiles
and tubes, extending our position as one
of the leading worldwide companies for
semi-finished plastics, which are used
in countless global applications, with
rods in large diameters being among
our specialties. Of course, we will
continue to produce custom products
on demand.
Innovation
Sustainability is not just a buzz word for
us. Together with Fraunhofer Institut, we
are exploring the possibility of extruding
wood. At present, we are extruding
biopolymers into semi-finished products
(PLA-L). Our R & D substantially benefits
from our know-how as a supplier of highquality tubes for the pen and cosmetic
industry, as well as the medical industry.
New developments are taking place all
the time. In addition to this catalogue,
we recommend that you regularly visit
our website for updates, as well as
subscribe to our quarterly newsletter,
where you will also be informed of all the
latest news from our company.

GEHR ECTFE (Halar®)
Ethylen-Chlortrifluorethylene exhibits an extraordinary impact strength at temperatures
ranging from -104 °F to +302 °F. A great part of the product properties attributes to
the very smooth surface and differentiates HALAR® from other fluoropolymers. Due
to the fact that E-CTFE is very pure, this material is being used to process chemicals
and ultrapure water for the semiconductor industry.
Also the permeation resistance to oxygen, carbon dioxide, chlorine gas and
hydrochlorid acid is 10 to 100 times better than PTFE.
Characteristics:
• extremely high impact strength (up to
-105 °F) no break on notched or
unnotched IZOD impact test
• very good weather resistance
• high resistance to radiation
• very high chemical resistance
• much more dimensional stability
than PTFE
• very good sliding properties
• food safe
• high density
• limited protection against stress
cracking at temperatures > 284 °F
• very low moisture absorbtion at < 0.1%
Applications:
Parts which come in contact with aggressive materials (machinery building industry),
lining of tanks, pumps, flanges, fittings, parts in centrifuges and control engineering
industry etc...

The metalloid (hard metal) or HSS (high performance superspeed steel) cutting tools should be used only sharpened.
Due to the danger of stress cracking we do recommend to use no cooling agents oil based
(or to clean the parts well after machining).
Amorphous materials should be annealed during machining.
(ABS, PMMA, PC, PPO, PSU, PPSU, PEI)
To avoid treatment problems we recommend a heating up of the materials on approx. 250 °F.
Use only sharpened tools with small feed.
(PEEK, PEI, PPSU, PSU, PA, PET, reinforced materials)
With these materials we should be paid attention to a good exhaust of the machining area.

Annealing guidlines of different thermoplastics
Despite all precautionary measures an uneven cooling speed in the
production process of the semi-finished material might not be avoidable;
in this case internal tensions might occur. Likewise tensions can be
conferred into the part by the machining process into the part. These
tensions can lead to the distortion and in the worst case even to the
breaking of the part. To reduce the danger from distortion or breaking
an annealing e.g. in air or in nitrogen is recommended, with an annealing
time of min. 2 hours (4 hours are better) for each 10 mm wall thickness.
To avoid additional tensions in the part by heating and/or cooling, these
processes which must be added to the annealing time and should be
persecuted slowly.

Since almost any material is subject to aging, therefore is only a limited life the expectancy.
Following factors have influence on the chemical stability: Temperature, duration, concentration, tension level of the part, mechanical strength, etc.
From the data of the list of the chemical stability the suitability of a material cannot be judged without above mentioned restrictions.
In special applications it is up to the user to determine the suitability of the plastic by running trials in real time.
