Heat Dissipating Plastic suits LED applications.
September 12, 2008 -
With inherent EMI/RFI shielding characteristics, non-corrosive CoolPoly® thermally conductive plastic provides low CTE and thermally conductive mass to help transfer/dissipate heat close from LEDs with no secondary interfaces at die level. At board level, it provides 3D molded substrates that transfer LED energy similar to ceramic boards and metal backed boards, and can be injection molded to net shape that serves as heat sink and mechanical enclosure at enclosure level.

LED Lighting Can Now Benefit from Latest Cool Polymer Technologies to Dissipate Heat, Increase Life of Units
WARWICK, RI (September 5, 2008) - A new thermally conductive plastic, CoolPoly® has been developed by Cool Polymers, Inc. of Warwick, RI expressly for managing the heat output of increasingly popular light emitting diodes (LEDs). While conventional plastics act as thermal insulators, the new CoolPoly thermally conductive plastics dissipate heat to enable LED lighting designers turning to LEDs to mold thermal management into their LED luminaires. This enables them to achieve more light and longer lifecycles for the LEDs.
With the potential for cutting electricity consumption by as much as 60-90% by replacing incandescent bulbs, LEDs are nearly 10X more efficient than incandescent lights. Further, they last 10X longer and require no special handling or cause no environmental impact when disposed.
As with other forms of lighting, heat remains a major problem, cutting into the 15 year expected life efficiency of LEDs. The new CoolPoly thermally conductive injection molded plastics from Cool Polymers manage the heat output of LEDs when used at the die, board and enclosure levels to reduce temperatures, enhance brightness, and increase lifetime.
Other benefits include:
o Can easily be molded to ensure a robust housing
o Offers low thermal resistance
o Economical to use with range of base resins and thermal conductivities
o Provides 3-dimensional complexity
o Low weight
o Can provide added convective surfaces
o Can have molded-in thermal interface and component integration
o Dielectric, low CTE for direct mounting of LEDs
o Provides inherent EMI/RFI shielding characteristics
o Non-corrosive and RoHS compliant
At the die level, the new CoolPoly thermally conductive dielectric plastics provide low CTE and thermally conductive mass to help transfer and dissipate heat close from the LEDs with no secondary interfaces.
At the board level, the new CoolPoly thermally conductive dielectric plastics provide 3-dimensional molded substrates that transfer LED energy similar to ceramic boards and metal backed boards.
At the enclosure level, the CoolPoly thermally conductive plastics can be injection molded to a net shape that serves as a heat sink and a mechanical enclosure. The new CoolPoly thermally conductive plastics transfer heat equally as well as aluminum, are half the weight and are also more cost-efficient than aluminum.
Cool Polymers engineers can provide luminaire designers and manufacturers with complete guidance from product application and concept review through part design and molding resources.
Cool Polymers, Inc. is the originator and undisputed leader in thermally conductive plastics, with more than 100 million customer molded parts in use. The firm also provides off-the-shelf and custom parts made from these proprietary plastics, plus full design and prototyping assistance.
Products and services also available from the company include D-series (dielectric) and E-series (electrically conductive) thermally conductive plastics, 3-D dielectric heat plates, thermal interface and gaskets, functional heat sinks, compression molded solid shapes, and complete design and prototyping services.
