Carbide end mills
EMUGE Corp has introduced Top Cut™,
a new series of high performance carbide
endmills. Offered in awide range of metric
and inch sizes, styles and geometries,
Top Cut provides versatility in milling
a broad array of materials, including
hard steel at up to 55 HRC. Suitable for
mould and die as well as general milling
applications, Top Cut end mills feature a
new variable helix flute technology and a
newly developed variant of the high heat
resistant TiAlN coating. These features,
in addition to internal coolant capabilities,
enable efficient material removal with
minimal vibration and wear.

Polymers
and pests
POLYMERS and plastics are widely
used and form the base of a host of
materials. As large as their use is,
even larger is the threat they face
from rodents and pests. Rodents are
attracted by the sweet smell of polymers
and consequently rodent damage is one
of the most widespread complaints from
the pipe industry.
Gas pipelines, drip irrigation pipelines,
and tubing for wires and cables are
some of the most-affected by pests.
Damage to gas pipelines can have
adverse consequences. Damage to
drip irrigation pipelines by rodents and
subterranean termites not only defeats
the purpose of water conservation
but it is also expensive to replace the
pipe. Damage to the tubing and wiring
harness of automobiles by rodents can
cause thousands of dollars in losses.
Conventional methods of rodent and
termite control fall short, as they do
not effectively control the pests. Also,
being toxic they cannot safely be used
in all applications. It is imperative to
effectively solve the problem of polymer
piping damage by pests and also to
provide a long-term solution. With this
aim, and keeping in mind environmental
as well as safety aspects, Rodrepel® ™
and Termirepel®™ were developed by C
Tech Corporation.
Rodrepel and Termirepel are
patented non-toxic, non-hazardous
and environmentally friendly aversives
specially developed as a master
batch for use in polymeric and coating
applications. The products are RoHS-
and REACH-compliant, and FIFRA
exempted.
They deter the pests by making use
of the sensory mechanisms. They do
not interfere with the properties of the
polymer and are completely inert within
the polymer matrix, apart from acting as
an aversive. Rodrepel and Termirepel
do not volatilise and are compatible with
all kinds of polymers.
They have undergone extensive
testing at testing institutes like the BAM
Institute in Germany and the Haffkine
Institute in India.
