TC Poly is developing the world’s highest thermal conductivity pure plastic material for thermal management application in the batteries and LED markets. The proprietary material boasts a thermal conductivity 25x greater than conventional plastics, allowing for advanced cooling capabilities. The material is lightweight, electrically insulating, and can be processed using traditional injection molding techniques. By replacing standard plastic components with our material, customers can achieve enhanced thermal management capabilities and unrivaled design flexibility.

Figure AHeat removal in electronics is increasingly difficult because of the ever-growing computing power and the limited space for heat sinks as electronics become smaller and lighter. Hence, thermally conductive plastics have emerged as an attractive class of low-cost materials to replace traditional plastics and reduce device operating temperatures.  The market for thermally conductive plastics is expected to grow to $1.9 billion as manufacturers seek out more cost-effective heat dissipation solutions. Through customer discovery in the NSF I-Corps program, TCPoly has learned that the market is being driven by the need to reduce chip, battery, and touch temperatures in consumer electronic devices.  The below figure demonstrates the power of the TCP casing to dissipate heat. A large hot spot occurs when a local heat source is applied underneath a normal non-

conductive plastic (Figure a). A common solution in consumer electronics is to add a metal plate underneath the plastic adding cost, complexity, and weight to the casing (Figure b). By making the electronics casing out of the TCP material (Figure c), the temperature is reduced to the same level or lower than with a metal plate but without the additional weight and complexity. In this simulation, by switching to the TCP material the casing temperature is reduced from 68°C to 29°C without adding any additional weight or manufacturing steps to the electronics part. This temperature reduction has been verified in lab testing and TCPoly is now working with several partners in the consumer electronics industry to develop prototypes for applications testing.

Interview with Co-Founder Thomas Baugher

Can you tell me a little bit more about your background?                           
I’m from Ohio originally by way of Indiana and Texas. I went to Purdue for undergraduate and UT-Austin for my Master’s. Prior to coming to Georgia Tech for my Ph.D. I spent 5 years working as an automotive engineer. I loved cars, but I really wanted to work on a next-generation technology, so I decided to come back to school to get my degree and do research in nanomaterials. Research in nanotechnology is so motivating to me because the possibilities are so big. In a refined technology like an internal combustion engine improvements of a single percent are meaningful, while in making a new nanomaterial you might change a property by a factor of 50. I also find the startup environment exciting, because things can be very dynamic. I get to make new materials, build test rigs, write code, talk to customers, and develop a strategy. Constantly changing hats keeps things fun.

What sparked the idea for TCPoly?                            
My co-founder Matt Smith and I were both working on thermally conductive polymers in the same graduate research group for four years, and we were both interested in commercialization. Prior to my graduation at the end of 2015, we decided we should try I-Corps to see if our idea had any merit for commercialization. We found that the initial application of our technology probably wouldn’t have good traction, but that it could easily be adapted to a different application. I decided to stay at GT instead of taking a job at a semiconductor company on the West Coast because I think we have a great chance at being successful in commercializing this technology. Matt is a born entrepreneur, and he enrolled in graduate school with the intention of starting a company; he’s been leveraging GT’s great resources throughout his graduate studies including VentureLab startup gauntlet, ATDC seminars, and the TiGER program to help us get a head start on our company.

How do you describe your technology to someone who does not have a background in tech?                            
We are making plastics that can keep your electronic devices cooler. Our material can be used for a variety of applications such as the case of a cell phone, the frame of a cable box, an LED light housing, or the casing of a battery. By changing the structure of these materials we can make them conduct heat more like a metal than a plastic, but lighter and less expensive.

During the I-Corps program, what did you find most surprising? Did you have a major pivot?                            
We had been working with several major electronics companies throughout our research so we felt we understood the industry fairly well and the challenges of commercialization. During the I-Corps program, we quickly realized that we understood the some of the technical challenges, but not the business side or the degree of cost sensitivity. We did go through a major pivot at the end of the program. We stayed in the electronics market but shifted the way our materials would be used. That pivot led us to the current version of the technology we’re making today.

What was the most consistent feedback that you got from your Customer Discovery?                            
I-Corps was a very valuable experience for us because it taught us to look for how our material can enable parts to be re-engineered for better performance and cost savings. Thinking in terms of value propositions instead of technical specifications as the instructors would say. The top item of importance was consistently cost. Even when an engineer would get really excited about how our technology would enable better performance of his device, the sentence would still end with “…and if you could make it cheaper too, that’d be great!” We’ve carried that lesson into the way we’re currently working on scaling our material to keep costs as low as possible.

What is your goal for TCPoly?                            
I think we are at an exciting time to be starting a company with a new type of plastics for electronic devices. People in industry are only now starting to think that maybe the housing of a device could help dissipate heat, and our material is well-suited to become established on the ground level of this shift in thinking for electronics packaging. With the great resources around Atlanta and GT and some great mentors, my partner and I want to grow this business in Georgia and see how far we can take it.
