PureTemp introduces temperature-control fabric coating

Ben Welter - Wednesday, January 23, 2019

PureTemp LLC has developed a fabric coating engineered to provide an effective buffer against ambient temperature swings in consumer products such as apparel, footwear, bedding, safety, medical, workwear and industrial applications.

PCMs absorb, store and release thermal energy as they cycle between solid and liquid states. The PCM coating interacts continuously with the unique microclimate of the human body, storing and releasing energy to balance body temperature and increase comfort.

PureTemp honeycomb pattern coatings are available for knit, woven, interlock, circular knits, nonwoven, cotton, polyester and other blends. The photo above shows what PureTemp coated fabric looks like under a scanning electron microscope.

The Minnesota company began producing the world’s first 100 percent biobased PCMs in 2007. PureTemp PCMs, developed in three years of research sponsored by the U.S. Department of Agriculture, are used in a wide variety of temperature-control applications, from cooling vests and warming blankets to shipping containers and coffee mugs.

PureTemp's Dan Keller is directing the business initiative. For more information on PureTemp coated fabrics, contact him via inquiries@puretemp.com or visit https://www.puretemp.com/fabrics.
