Therma-Tech™ Solutions Brighten the Future
for LED Lighting Innovators
Transitioning from metal to a PolyOne solution meets performance
targets and improves manufacturing efficiency and sustainability.
Situ a tio n
The use of Light Emitting Diode (LED) technology in place of incandescent,
halogen and fluorescent lighting systems is rapidly emerging as an important new
trend in residential and commercial lighting. Factors driving the demand growth
of LEDs in these applications include the need for improved energy efficiency,
eco-conscious brand owners and legislators, and the widespread push to reduce
electrical consumption and greenhouse gas emissions.

Therma-Tech formulations provide designers with greater
freedom to achieve required thermal conductivity, and
also meet important dielectric, mechanical, flammability,
dimensional stability and creep resistance requirements.
Perhaps best of all, Therma-Tech material processes like
conventional thermoplastics, expanding part design freedom,
simplifying manufacturing, and reducing total systems cost.
T h e P o ly O n e D if fe r e n ce
Kruunutekniikka Oy, a Finnish manufacturer of lighting
components, sought a heat exchanger material solution that
would facilitate cooling of these components without the
need for aluminum. Coolics™ (www.coolics.fi), a patented new
thermal interface from Kruunutekniikka, has been developed
with the use of customized Therma-Tech materials that offer
thermal conductivity in plane from 2.7 to 21 W/m.K (ASTM
E1461).
Therma-Tech materials also provide the required flammability
performance with a glow wire resistance of 850°C/0.8mm (IEC
60695-2-12), plus the high dimensional stability necessary for

For an LED lighting system to be an effective alternative
to traditional lighting, it must be designed to dissipate the
excess heat generated by LEDs. Materials such as aluminum
have traditionally been used for this purpose, but cast
aluminum is both heavy and expensive to manufacture. In
contrast, Therma-Tech™ thermal management polymers from
PolyOne are formulated to meet the exacting performance
requirements of thermal interface components, including
sockets, heat sinks, transfer pads and trim, with improved
design and manufacturing flexibility.

them to be directly overmolded on LED packages.
PolyOne’s sales and technical team listened carefully to Kruunutekniikka’s stated needs and requirements for this innovative
thermal interface. Addressing the challenge, experts from PolyOne worked closely with Kruunutekniikka and proposed a
combination of two customized Therma-Tech grades offering the features required for the application.
Therma-Tech solutions also gave Kruunutekniikka an economic advantage versus the die-cast aluminum parts it had been
using for its lighting system heat exchangers and components.
D elivering a Value- A dde d So lu tio n
Close collaboration between PolyOne and Kruunutekniikka resulted in a thermoplastic solution that met critical performance
needs and optimized the manufacturing process, which resulted in cost savings of more than 10 percent.
Lower Material Usage: The selected Therma-Tech solutions are 33 percent less dense than die-cast aluminum, so the
amount of material required per unit decreased accordingly.
Improved Manufacturing: By using the injection moldable Therma-Tech formulation rather than traditional die-cast aluminum,
Kruunutekniikka was able to realize substantial cost savings during high-volume production. The process switch also
accelerated production startup time. In addition, die casting requires secondary steps to achieve net shape, and these steps
were eliminated by switching to the injection molding process.
Sustainability: Production scrap generated during injection molding of Therma-Tech can be fully recycled as part of an in-line
process, which helped Kruunutekniikka to meet its sustainability goals.
Working in close collaboration with PolyOne, Kruunutekniikka is able to drive growth in the emerging solid-state LED lighting
market with a cost-effective solution that meets its goal of enabling a lower environmental impact.
PolyOne offers specialized solutions that are targeted at helping customers meet performance and sustainability goals, improve
manufacturing efficiency, and maximize value in every way possible.
