The company’s Lexo mug, which features stainless steel walls and a biobased lining, maintains a “comfortable drinking temperature” for up to eight hours.
“Before you pour hot coffee into it, the material is solid, but after you pour the coffee, the [biobased] material turns to liquid and absorbs the thermal energy,” Hongbin Ma, director of the University of Missouri’s Center for Thermal Management and a ThermAvant founder, tells the Associated Press.
Available on Amazon, over 650 mugs of the 10-ounce mugs have been sold, and a 16-ouce version is set to be launched this spring.
The company was originally founded to provide thermal-management solutions to the military. Ma begin working in consumer products in 2015.
