LATICONTHER®: HEAT TRANSFER AND DESIGN
PRELIMINARY REMARKS
LATICONTHER family provides the option
to manifacture products using thermally
conductive thermoplastic compounds.
The use of these materials allows a better
transfer of heat generated, for example, by
electronic devices due to the high thermal
conductivity provided by the special fillers
dispersed inside the thermoplastic matrix.
So, new interesting applications may be considered
for projects requiring the removal of locally
generated heat when conventional metal solutions
cannot be considered or are to be replaced with
simpler or more cost-efficient alternatives.
LATICONTHER products offer many advantages
compared to metallic materials:
a. lower weight,
b. high chemical resistance of the plastic
matrix in aggressive environments,
c. low thermal expansion values, compatible
with the different types of substrate,
d. possibility of combining thermal
conductivity with electrical insulation,
e. colourability without resorting to paints,
f. overall cost reduction for the
manufacturing process,
g. possibility to integrate complex
geometries made up of inserts or several
assembled parts in a single process
operation.
The great advantage of easy and clean
management of waste and scraps, which can be
easily recovered or disposed of, is also worth
mentioning, as well as the absence of washing or
cleaning cycles requiring the use of solvents or
acid baths, and the conversion at definitely lower
temperatures compared to metals.
For all these reasons, LATICONTHER is a
successful solution also in terms of health and
environment.
Thanks to these properties, LATICONTHER range is
a valid solution for encapsulation and overmolding
of electrical components such as inductors and
reactors, the manufacture of heat sinks for electric
motors, processors, active components (e.g. power
transistors), LED lamps, etc.

LATICONTHER®: HEAT TRANSFER AND DESIGN
HEAT TRANSFER
Energy transfer due to the relative temperature
difference occurs through three mechanisms:
conduction, convection and radiation.
•
Conduction: transfer due to the contact with
systems having different temperatures.
The amount of heat transferred (Q) is a function
of the geometry, properties of materials
involved, and temperature difference (ΔT)
where s is the thickness and A is the area of
heat exchange.
The thermal conductivity (K) describes the
material’s ability to transfer heat and is an
extremely variable measure:
Qconduction = −
K ⋅ A ⋅ ∆T
s
Fig. 3 - Example of natural and forced convection.
•
Radiation: energy emitted by a body in the
form of electromagnetic waves due to the
vibratory and rotatory motion of molecules,
atoms and electrons within a substance; they
are a function of material and temperature.
Fig. 4 - Example of electromagnetic radiation.
Fig. 1 - Materials with high and low thermal conductivity.
The overall phenomenon of heat transfer is often
simultaneously made up of the three above
mentioned mechanisms.
So the combined evaluation of the individual
contributions is crucial to optimize the overall
system efficiency.
Fig. 2 - Thermal conductivity of some substances.
•
Convection: energy transfer between a
solid surface and a fluid. The thermal power
transferred is a function of the exchange
surface A of the component and of the
temperature difference (∆T) between the two
systems:
Qconvection = h · A · ΔT
The convection coefficient (h) regulates the heat
exchange between the different systems, and is
not a property of material, but of the overall
system.
For example, the amount of heat removed from
a surface exposed to still air (natural convection)
is lower than that extracted from an airstream
(forced convection), the exposed surface area and
temperature difference being equal.
03
For example, in the case of a common heat sink
used for cooling a microprocessor or a LED lamp,
even though it is usually made of metal, in most
cases it may be replaced with a version entirely
molded in LATICONTHER.
In fact, it is often erroneously supposed that the
heat exchange capability primarily depends on the
intrinsic thermal conductivity of the material used.
Actually, the efficiency of the convective exchange
on the radiating surface (only influenced by
the geometrical properties of the body and the
surrounding air) greatly affects the overall balance.
For this reason, high thermally conductive metals
used, such as aluminium or copper, may be often
oversized, especially if the overall heat transfer
balance is jeopardized by other “bottlenecks”
involved in the heat transfer process, such as a
poor convective exchange due to a non-optimized
geometry.
LATICONTHER®: HEAT TRANSFER AND DESIGN
HOW TO CHOOSE?
After determining the product type, the specific
grade can be determined by selecting the most
suitable matrix based on application requirements.
When choosing a thermally conductive
LATICONTHER compound that best suits the
project’s needs, it has first to be determined
whether a material that is also electrically
conductive can be used or the use of an electrically
insulating material is definitely required.
LATICONTHER compounds are therefore divided
into two broad categories:
•
•
1. What temperatures are involved?
Heat may damage compound properties; an
evaluation of maximum and minimum project
temperatures is crucial.
2. In what environment will the product be
used?
Factors such as chemical etching, exposure
to sunlight, harmful weathering conditions or
atmospheric humidity play an important role in
the choice of polymers.
Electrically insulating: LATICONTHER CP
Electrically conductive: LATICONTHER GR
3. What mechanical performance is
required?
The presence of both static and dynamic
mechanical stresses is a decisive factor in the
choice of a compound.
4. Are self-extinguishing properties
required?
LATI also offers thermally conductive
compounds with UL-94 certifications.
If the project is not subject to explicit restrictions
concerning electrical insulation and the black
color is not a problem, the best choices in terms
of performance and price are certainly graphite
filled, electrically conductive LATICONTHER GR
compounds.
On the other hand, when project specifications
require electrical insulation and/or colors other than
black, the choice of LATICONTHER CP compounds
with special electrically insulating and colorable
fillers is recommended.

CONDUCTIVE AND
ELECTRICALLY
INSULATING
LATICONTHER 47/1 CP/80
PPc-based compound featuring excellent flexibility
and impact resistance, so particularly suited to
refrigeration applications even for extremely low
temperatures (e.g. liquid gas).
This material is also suitable for the extrusion of
simple profiles.
LATICONTHER CP and CP1 provide excellent
thermal conductivity without giving up the
prerogative of the polymers, namely the electrical

using special ceramic fillers ensuring effective heat
transfer as well as excellent electrical insulation.
The materials thus obtained are also colorable,
compatibly with the high amounts of ceramic
powder based on the formulation.
If a thermal conductivity of 1-2 W/mK is
satisfactory, then LATICONTHER CP compounds
may be the response to the project requirements.

LATICONTHER®: HEAT TRANSFER AND DESIGN
LATICONTHER GR:
THERMALLY AND
ELECTRICALLY
CONDUCTIVE
LATICONTHER GR products allow to reach higher
thermal conductivity values, thus providing much
better performance compared to conventional
thermoplastic compounds.
These compounds are filled with high percentages
of special graphite providing the material with
both longitudinal thermal conductivity with values
ranging between 10 and 15 W/mK and low surface
electrical resistivity.
Regardless of the base polymer matrix,
LATICONTHER GR products are not colorable, as the
used filler necessarily features black color.
Graphite used shows geometric anisotropy due to
the asymmetrical shape of the particles it is made
of.
Despite the high graphite content (up to 70% by
weight), LATICONTHER GR products do not require
special equipment for transformation; in fact, the
compound formulation was optimized to allow the
filling of even very thin walls.
LATICONTHER 52/11 GR/70
PPh based compound with excellent chemical
inertia, light weight, electrical and thermal
conductivity (more than 15W/mK), and outstanding
price/performance ratio.
This grade can be also used for the extrusion of
appropriate profiles.
LATICONTHER 62 GR/50 n
PA6 based compound with excellent both
longitudinal (more than 10W/mK) and transverse
thermal conductivity and good use properties at
high temperatures.
The high fluidity of the melt allows the filling of
even thin sections.
So even better thermal properties may be obtained
if filler is appropriately oriented:
conductivity will be higher in the direction parallel
to the feed direction of molten material flow filling
the product cavity.
Fig. 9 - Vossloh Schwabe heat sinks in
LATICONTHER 62 GR/50.
LATICONTHER 62 GR/50-V0

self-extinguishing and outstanding dimensional
stability.
Excellent chemical inertia and resistance to
aggressive environment.
07
LATICONTHER®: HEAT TRANSFER AND DESIGN
The development of LATICONTHER range coincided
with the emergence of LED as a new light source
with high efficiency and low environmental impact.
The need to ensure a good cooling of LEDs and
enclose its control electronics has been met with
radiating elements acting at the same time as
container, avoiding metal items where allowed by
operating parameters.
The thermal performance of thermally conductive
compounds, although not numerically comparable
with that of metals, is often widely sufficient for
proper LED operation, especially in the presence
of natural convection, i.e. in the absence of forced
ventilation.
LATICONTHER 87/28 GR/50
Project requirements:
The LED lamps for swimming pools developed
by BVR Electronic require maximum waterproof
properties and dimensional stability. The PCbased thermally conductive compound allows
proper cooling of LEDs, water tightness, and
welding of graphite filled base to the clear lens.
LATICONTHER 62 GR/50
Project requirements:
A complete range of sinks for LED lamps of
various power ratings, also suitable for flush
mounting. With this business card, VOSSLOH
SCHWABE relies on radiators molded in thermally
conductive resin for the cooling of its spotlights.
If properly designed, the polymer sink can keep the
LED temperature far from the junction threshold.
So sinks can be manufactured by injection molding,
even colorable or paintable, weldable, safe and
reliable, without having to accept compromises and
costs of metal processing.
For this reason their use is desirable at relatively
low powers, e.g. interior lighting, but cases where
high power has to be dealt with should be carefully
checked, such as in the case of headlights or street
lighting.
LATICONTHER 62 GR/50
Project requirements:
LUCEPLAN aims at the development of lighting
products featuring a unique and innovative design.
The radiator for the LED lighting element becomes
an integral part of the Tivedo lamp, finally in
plain sight thanks to the hand of the designer
who also dresses the technical parts.
LATICONTHER 52/11 GR/70
Project requirements:
The presence of potentially explosive atmospheres
can lead to the formation of electric discharges
and sparks that act as a trigger. To cool the LEDs of
professional torches, FANTON has chosen the thermally
conductive and antistatic compound instead of metal.

LATICONTHER®: HEAT TRANSFER AND DESIGN
MEASUREMENT OF
THERMAL CONDUCTIVITY
Polymer melt
The thermal conductivity measured in
LATICONTHER compounds may not be perfectly
identical in the directions of space, especially
if high-efficiency but geometrically distinctly
anisotropic fillers are used, such as, for example,
graphite and boron nitride.
The thermal conductivity values on the plane (Kx
and Ky) and through the plane (kz) are determined
by the feed direction of the molten compound.
The structure of these ceramics is almost two
dimensional, and for this reason the orientation of
conductive particles in the product may be quite
marked due to stresses to which they are subjected
during the injection molding process.
The motion and position of these particles are
determined of course by the molding parameters,
but especially by the wall thickness and the position
of the feeding point.
It can be easily understood that the ability to
transport heat along the orientation plane and
transversely to it is determined by the arrangement
of conductive fillers in the molded part.

LATICONTHER®: HEAT TRANSFER AND DESIGN
E1530 and E1461-92 standards.
Typically, very similar values are observed in
the two directions Kx and Ky of the plane, but
the conductivity through the Kz plane may be
significantly lower.
The data sheet attached to LATI materials shows
a value obtained by the elaboration of Kx, Ky and
Kz, and is intended to represent approximately the
thermal performance of the material.
Thermal conductivity is measured by LATI for its
compounds in the three directions of space using a
LASER-Flash Netsch LFA device according to ASTM
Fig. 10 - LFA 467 HyperFlash®, Light Flash Apparatus.
