Common Questions

Frequently Asked Questions

PureTemp specializes in biobased, renewable phase change materials with precise transition temperatures, long-term durability, and proven performance across tens of thousands of thermal cycles.

Phase change materials (PCM) are substances that absorb and release thermal energy during the process of melting and freezing. When a PCM freezes, it releases a large amount of energy in the form of latent heat at a relatively constant temperature. Conversely, when such material melts, it absorbs a large amount of heat from the environment. PCMs recharge as ambient temperatures fluctuate, making them ideal for a variety of everyday applications that require temperature control.

PureTemp PCMs are used across a wide range of industries, including cold-chain logistics, life sciences, food and beverage, building materials, and consumer products — anywhere consistent temperature control is critical.

Unlike petroleum-based phase change materials, PureTemp PCMs are nontoxic and have a low flammability rating. Many PureTemp® PCMs are composed of materials certified by the U.S. Food and Drug Administration as food-grade chemicals.
