GLOBAL AUTHORITY ON PHASE CHANGE MATERIAL

Food for Good program participants

No refrigeration? No problem

PepsiCo established the Food for Good program in 2009 to deliver meals to kids in underserved neighborhoods during the summer. But the expense of refrigerated trucks limited the program’s reach. In 2010, PepsiCo began working with PureTemp to find a solution. Together they created the Cold Box, an inexpensive and reusable container that keeps food at a safe temperature for hours without refrigeration. It’s powered by PureTemp 1. Read more

Thermal conductivity: Here's why it matters

Increased thermal conductivity allows for a faster rate of heat transfer in phase change material, reducing the time required for the PCM to undergo a complete charge or discharge. Read more
