With offices in Minneapolis, Minnesota, PureTemp has been at the forefront of PCM technology since 2007 when they developed the world's first 100 percent renewable phase change material. These patented PCMs are derived from sustainable sources like animal fat and plant oil and are non-toxic and biodegradable.

PureTemp's phase change materials find applications in various temperature-control settings, including cooling vests, warming blankets, refrigerators, and thermal energy storage tanks. These materials are engineered to maintain over 200 different transition temperatures consistently and provide repeatable performance. PureTemp has formed exclusive partnerships with industry-leading companies like Sonoco ThermoSafe and Glacier Tek.

Sonoco ThermoSafe utilizes PureTemp PCMs in its temperature assurance packaging for the safe transport of pharmaceuticals and biologics. Glacier Tek, on the other hand, offers body cooling products powered by PureTemp phase change materials. With numerous awards and recognition for their innovation, including the USDA Biobased Product Certification, PureTemp continues to be a global authority on phase change material technology
