Thermally Conductive Polymers – Heat Management

The Protool Plastics Group have pioneered the use of polymer composite materials as alternatives to aluminium castings for LED lighting.

Thermally conductive polymers give significant design advantages over aluminium allowing much more complex shapes to be produced.

Polymers are available in electrically insulating and electrically conductive versions and at commercially acceptable pricing.

With a high temperature PA66 base carrier the heatsinks display significant mechanical strength compared to the majority of existing products on the market.

Thermal Performance

Thermally conductive polymers up to 14.0 W/mK ensures that even the most demanding products can be catered for.

Electrically insulating material – 5.0 W/mK

Electrically conductive material – 14.0 W/mK

Sales Director Michael Hadfield commented “Thermal designers assume that thermally conductive polymers can never compete with traditional heat sink materials such as aluminium.

However thermal transfer is only part of the story and innovative design plays a massive part in meeting customer demands.

Much more creative designs can be made in polymer at a fraction of the cost of aluminium die cast tooling.

Product Design & Verification

Your initial product design model will be critiqued by our design team and the thermal performance verified by latest level thermal software.

Reflectors, diffusers or housing enclosures can be modelled to ensure that accurate results are gained at all times.

Clever design and the easy mouldability of these polymers allow for much more complex designs often incorporating several parts into one moulding, saving tooling cost and assembly times with less parts in an assembly.

For really demanding applications we have developed our unique hybrid heatsink which is an aluminium polymer composite and is used by companies such as BritLED and Havells Sylvania.
