BASF now offers a new and patented
version of the foam Neopolen P (EPP: expanded polypropylene) for
devices used in heating, ventilation and sanitary systems. The
metallic-gray Neopolen P 9335 mg is noted for its thermal
insulation which is 10 percent better than standard EPP.

insulation which is 10 percent better than standard EPP. The foam
serves as packaging for transportation, supports the device as
constructive carrier and replaces the metal housing because it can
be processed into thermally insulating housings with an aesthetic
surface (see insert). Photo: BASF - The Chemical Company,

Thanks to the versatile properties of the new product, foamed
Neopolen P molded parts are able to perform several functions at
the same time: The foam serves as efficient shock-absorbing
packaging for transportation, supports the device as constructive
carrier and replaces the metal housing because it can be processed
into thermally insulating housings with an aesthetic surface.
Neopolen P 9335 mg thus helps to meet the energy standards of
low-energy houses and for the renovation of older buildings.
Several functions in on
This presents new design options for devices such as heat
exchangers and solar storing units. Neopolen P 9335 mg can be used
to foam highly resilient, elastic molded parts which replace
conventional metal or injection-molded housings. Without any
elaborate mold design, undercuts can be produced in the foam
component easily and cost-effectively. This provides new options
for integrating additional functions into the housing such as
airflow channels or assembly fixings. As a result, the required
number of components can be reduced to a minimum. The thermal and
electronic units are fastened directly into the viscoplastic
Neopolen P housing. Thus, they cannot be damaged during
transportation.
When in use, the device is also thermally insulated in an
efficient way. The polymer matrix of Neopolen P 9335 mg contains
infrared absorbers which reflect thermal radiation like a mirror
and thus considerably reduce the heat transfer compared to
conventional EPP. Neopolen P is temperature-resistant from
-40°C to +100°C.
Designed surfaces
Thanks to new tooling technologies, the foam can be processed in
such a way that high-quality surfaces are produced without the
typical particle foam look and without nozzle imprints. The foam
beads which expand uniformly adapt to the modified mold surface and
as a result generate a homogeneous, aesthetic designed surface, for
example with a leather look.
Neopolen P - versatile and environmentally friendly
Neopolen P 9335 mg is a specialty foam from the tried-and-tested
Neopolen P product range. The expanded polypropylene (EPP) is noted
for its very good shock absorption characteristics, low weight and
high temperature resistance. The particle foam combines high energy
absorption - even after several impacts - with excellent resilience
and isotropic deformation performance. This interesting combination
of properties, which also includes low water absorption and good
resistance to chemicals, opens up a broad range of applications:
from vehicle construction, packaging and transport containers to
sports and leisure applications. Neopolen P is 100 percent
recyclable. It is manufactured and processed without any CFCs
(chlorofluorocarbons).
