OmniTemp™ - Peterson Chemical Technology

OmniTemp™ is a new generation of Peterson viscoelastic
foams, designed to have a distinctively luxurious feel
while maintaining the high performance and durability
of Peterson CoolFlow™ visco technology. OmniTemp™
is formulated to have an exceptionally low Glass
Transition Temperature (Tg), which results in high
pressure-relieving capability across an extended
range of extremely low temperatures. For this reason,
OmniTempTM
Luxurious Open-Cell Visco
OmniTemp™ foam will never stiffen in a cool bedroom and some grades can be used even
at below freezing temperatures without becoming stiff. This is the next evolution of
conductive Peterson CoolFlow™ open-cell polymer technology, which produces
breathable and odorless foam with greatly enhanced heat flow. OmniTemp™ technology
magnifies these benefits of CoolFlow™ in an effort to maximize sleep comfort at an
extended range of cold temperatures.
Breathability and Temperature Control
The excellent air and heat flow of PCT
OmniTemp foams afforded by their
extremely open polymer structure can be
highlighted against standards of soft latex
and conventional visco at a similar
density and IFD.
A breathability
comparison against these standards, as
depicted in Figure 1, shows an air flow
improvement of up to 20 fold. This
essential property ensures a much cooler
and more comfortable sleep by enabling
excess body heat and moisture to be
quickly and effectively transferred away
from the body.

Thermal management in OmniTemp™
foams is achieved by efficiently
transferring heat through the open
cells of the foam and conductive struts
of the polymer, both of which rapidly
channel excess heat towards the
uncompressed parts of the mattress
where it can be liberated through
convection. Compared to conventional
visco and a soft latex foam described
above, OmniTemp™ visco transfers
heat significantly faster during the
Dynamic Thermal Conductivity (DTC)
test, in which pre-heated foam samples
are cooled under controlled conditions
(Figure 2).

Figure 2: Cooling Rate Comparison of Foams
Because the DTC measures how rapidly
certain foam types can transfer away
heat, it can be used to assess their
cooling capacity and efficiency. Based
on the rate of cooling, a heat flow value
is calculated according to the test
methods described in PCT-101A-01,
which represents how much heat the
foam can transfer over a set amount of
time. The calculated DTC values
presented in Figure 3 show that the
OmniTemp™ visco transfers heat more
than 13 times faster than conventional
memory foam and up to 16 times faster
than the soft latex foam sample.

Temperature Performance Range:
OmniTemp™
visco
foams
are
designed to perform over an
exceptionally wide temperature scale,
maintaining their soft and comforting
feel in any sleep environment.
Normally, memory foam gets firmer
in cooler environments, and some
bedding products even become
unpleasantly stiff in a slightly cool
bedroom.
Peterson
CoolFlow™
technology addressed that problem
and extended the low temperature
performance range significantly,
Figure 4: Effect of Cool Temperatures on Different Foam Types
while still remaining a product for
indoor use only. The OmniTemp™ technology takes viscoelastic foam to a whole new
temperature performance level, maintaining its luxurious and comfortable feel even at
below freezing temperatures. Figure 4 shows the extent to which different foam types, all
of which are 10(±1) IFD firmness at room temperature, respond to cold temperatures.
Figure 5 shows how the IFD curves of CoolFlow™ and OmniTemp™ foams change when the
samples are pre-conditioned to different temperatures before measuring their IFD’s,
demonstrating the OmniTemp™ as virtually unaffected by the freezing cold.
