Dear <<First Name>>,
Welcome to the latest 4PLAS newsletter, this month we want to focus on an interesting area of development within our high performance 4TECH range, namely Thermally Conductive Polymers.

As miniaturisation of electronic equipment and components gets more radical, thermal management becomes ever more important and the need for heat dissipation crucial, but to develop solutions first we need to understand the mechanisms involved.
Convection being a slower mechanism than conduction often means that using traditional conductive materials such as Aluminium or Copper can be useless if the design relies primarily on convection. This can be solved by adding a convection medium or by increasing surface area of the part. 

Our 4TECH® conductive range allow designers to use thermoplastic compounds, therefore allowing complex shapes designed to increase surface area to assist in heat convection away from components.
The thermal conductivity can be optimised in our 4TECH® grades by changing the type and orientation of the fillers used.  Grades can be formulated to give increased in-plane conductivity or through plane/perpendicular conductivity.
Using 4TECH® Thermally Conductive compounds we can design a material that offers either Electrically or Thermally conductive properties such as :  
  • In plane thermal conductivity coefficient up to 30 W/mK
  • Anti-static dissipation
  • Flame retardant if required
  • EMI/RF Shielding
Or Electrically Insulative & Thermally conductive properties such as :  
  • Electrical Isolation
  • Flame retardant if required
  • No Carbon Tracking
These properties can be utilised using a wide range of polymer base to ensure products designed for you and your customers specific requirements.
Should you wish to discuss these materials or any of our existing products further, or wish to suggest any topics or specific applications you want us to cover please let us know and we will try and include them.

Please feel free to contact us at or call us on 0870 446 0424 and we would be happy to assist.
