Freudenberg Sealing Technologies Process Seals Introduces Food-Grade Material
for Guide Bands
New PTFE compound increases service life for valves

PLYMOUTH, Mich., Sept. 5, 2013 /PRNewswire/ -- Freudenberg Sealing
Technologies Process Seals will introduce its new polytetrafluoroethylene
(PTFE) compound Y005 at Drinktec 2013 in Munich (Sept. 16-20, 2013, Hall A 4,
stand 441). Developed especially for use in guide bands on valves that come
into contact with foodstuffs, the material complies with the regulations of
the FDA and European Union (EC Regulation 10/2011) and also prolongs service
Guide bands compensate for lateral forces and extrusion in valves, which means
that the materials used must be extremely pressure-resistant. At the same
time, the guide bands must have a certain degree of flexibility in order not
to be damaged during assembly. The previously used combinations of carbon and
PTFE achieved good service life but were not recommended for food device
engineering. A benchmark test of comparable guide bands showed that they were
not capable of withstanding great force in valves; the direct consequence
being greater wear and thus shorter service life.
The main reasons for developing the special PTFE compound Y005 were therefore
to achieve a targeted balance between pressure resistance and flexibility,
authorization for contact with food, and resistance to CIP (Cleaning-In-Place)
and SIP (Sterilization-In-Place) cleaning products. Both at 80 degrees C and
120 degrees C Freudenberg's special PTFE compound displays up to 75 percent
less tendency to extrusion than other materials authorized for food contact.
The preliminary introduction of Y005 guide bands in series production of
valves has shown outstanding results. Device manufacturers confirm that this
special PTFE compound has a very good price / performance ratio because of the
long service lives achieved. These food-grade guide bands are currently
available as standard products in over 40 different sizes, with diameters from
19 to 100 mm and a variety of widths.
Drinktec 2013, which takes place at the Messe Munchen exhibition center in
Munich, is expected to attract over 1,400 exhibitors from more than 70
countries. For more information on Freudenberg products, including the Y005
compound, please visit the company's booth in Hall A4, booth 441 or visit our
