New hi-tech compound
for sports & leisure applications
The development divisions of Geba Kunststoffcompounds GmbH and
Covestro recently developed the Desmovit® DP R CF series, a range of
ester-based, carbon-reinforced thermoplastic polyurethanes.

his new, hi-tech polymer has many
of the positive properties of unfilled
thermoplastic polyurethane (TPU).
Desmovit® DP R CF impresses with its
high abrasion resistance and is also resistant to various oils and fats as well as hot
air and hydrolysis.

Excellent mechanical properties
With its mechanical properties,
Desmovit® DP R CF stands out from the
existing glass fibre-reinforced TPU grades.
This hi-tech compound has very good
flexural and tensile properties. Its tensile
strength, depending on the level of reinforcement, lies between 70 and 135 MPa,
and values of up to 5700 MPa have been

achieved for flexural strength. Due to its
combination of excellent tensile strength
and high impact strength and notched
impact strength, this material is suitable
for parts exposed to knocks and blows.
It is also worth mentioning that the new
plastic only becomes irreparably damaged
after a yield strain of 17.5%.

Wide-ranging applications
With its low density and high mechanical
properties, this material is ideal for the
production of protectors as well as protective cases for tablets and smartphones.
It prevents penetration by sharp objects,
absorbs impact forces and optimally
reduces the remaining energy. This hi-tech
TPU can be used in diverse applications
in the field of sports equipment, as well as
in durable housings for various fields of

application such as watches, tools and binoculars. This will ensure, for example, that
the optical components of the binoculars
will not be damaged through shocks and
knocks. In addition to its sophisticated
mechanical values, this carbon fibre-reinforced TPU is antistatic after a certain level of reinforcement and thus lends itself to
use in rollers, wheels and housings where
electrostatic charges are to be avoided. It
can therefore be considered for use in the
mining or chemical sectors, as well as for
industrial gear wheels. Due to its heat and
cold stability, this material is also ideal for
use in various outdoor applications. n
