One of TDL Plastics crowning achievements is our extensive knowledge and work with thermally conductive plastics. Our research in thermal conductivity has fallen into three main categories:
1. Thermal Conductivity: When we use this term, we mean the plastics part will conduct heat through the part with little heat build up. We have done a tremendous amount of research into the basic principals of this field. Plastic is a traditional insulator, and we have figured out how to overcome this natural tendency of the material in order to move the heat through the part. This type of heat dissipation or transfer is very important in the electronics industry for keeping things cool. As electronics become smaller and smaller while performing more and more operations, there is some real problems with heat build up within the parts. We have been able to develop an entire line of resins specifically designed to dissipate the heat out through the parts, thus helping to keep the internal parts of the device cool.
2. Thermally Retentive: Thermally retentive materials help either insulate the internal workings of the part, or the material will stay warm to the touch during and after use. We have developed this material for some applications needing the retention of heat for long periods of time, and it has worked very well in many of these types of applications. It allows designers to look at uses, much like radiant heat flooring, where the desired end result is a material that looks and feels like metal, and helps to hold the heat in for extended periods of time.
3. Thermal Sink: This is one of the most interesting uses of our material yet. For applications where the exposure to heat is short but very high, this material brings the heat into the part, and allows it to accumulate. Because of the high thermal capacity of the plastics, this allows the heat to build on one side of the part before transferring through the entire part. This is useful for parts that need to remain cool to the touch while the other side is very hot. This will allow for safe contact.
We have done extensive laboratory research on all of the above plastic materials, and have become leaders in the field when it comes to heat, additives, and plastics. Please do not hesitate to contact us and let us know what it is you are trying to do or would like to do with plastics, and we will show you how it is possible.
