PureTemp began producing the world’s first 100 percent renewable phase change material in 2007. These patented 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 refrigerators and thermal energy storage tanks. Derived from 100 percent sustainable sources such as animal fat and plant oil, PureTemp is nontoxic and biodegradable. It is engineered to maintain more than 200 different transition temperatures with consistent, repeatable performance.

Technical Data Sheets

Twenty-three PureTemp PCMs have been designated as 100 percent biobased by the U.S. Department of Agriculture’s BioPreferred program. Our proprietary formulations and patented manufacturing processes yield superior results at cost-effective prices.

Key properties include:
•    Heat energy storage capacities that average 200 J/g
•    Over 200 unique phase change transition temperatures between -40°C and 151°C
•    Consistent, repeatable performance over thousands of thermal (melt/solidify) cycles
•    100% renewable
•    Produced from agricultural sources, not petroleum
•    Readily biodegradable and nontoxic
