RTP Company Introduces New Series
of Highly
Conductive TPEs With Lower Durometer

WINONA, MINNESOTA, USA -- (July
9, 2008) --
 The
TPE Division of specialty compounder RTP Company has introduced
a new series of electrically conductive TPV-based thermoplastic
elastomer compounds - ESD C 2800 B Series . TPE materials combine
the functional performance and properties of thermoset rubbers with
the processability of injection moldable thermoplastics. These new
grades offer a Shore A hardness as low as 55, making them ideal
candidates to displace conductive EPDM rubber.
According to Paul Killian, Technical Marketing Manager - TPE Division,
"The addition of conductive fillers raises the modulus and
viscosity of materials, thus negatively affecting both flexibility
and processability. Historically, this has made it difficult to
obtain flexibility and feel similar EPDM rubber. These new compounds
achieve our goal of a highly conductive TPV material with good flexibility
and elastomeric feel, high tear strength and easy moldability."
ESD C 2800 B Series grades feature a volume resistivity of 100 ohm-cm
and consistent wide processing window across a Shore A hardness
range of 55-85. Compared to conductive EPDM rubber, conductive TPEs
offer a major manufacturing advantage because they are processable
by thermoplastic injection molding methods. The ability to injection
mold TPEs allows for design and fabrication freedoms that thermoset
rubber does not offer.
"Although targeted as a replacement for conductive EPDM rubber,
these products also provide a significant reduction in viscosity
versus previous conductive TPVs in the marketplace," said Killian.
"Injection molders will find these products much easier to
work with than conductive TPEs of the past. They are an ideal drop-in
replacement for applications where ESD protection with TPE properties
is needed."
RTP Company formulated the ESD C 2800 B Series in response to growing
market demand for softer TPV-based conductive TPEs. "Providing
a high degree of electrical conductivity while maintaining elastomeric
properties was a challenge," explained Killian. "RTP Company's
strength's are its strong engineering capabilities and expertise
with conductive and additive technologies that comes from being
a specialty compounder. We have combined that with our TPE Division's
knowledge base to create highly conductive TPEs without sacrificing
processing and performance advantages associated with TPEs."
