Entropy Solutions, based in Minneapolis, has partnered with Encapsys, Appleton Papers’ subsidiary, to microencapsulate its 100% renewable-based PureTemp phase change material (PCM).
Microencapsulation is the process of covering a core material with small capsules or shells. Encapsys applies this process to Entropy Solutions’ PureTemp PCM, a thermal energy storage product that collects, stores, and reuses energy to retain constant temperatures for longer periods of time.
PureTemp is developed to maintain over 200 different transition temperatures with repeatable and consistent performance. The product can be permanently encapsulated at any temperature, whereas other PCMs are restricted by temperature ranges and control methods. Microencapsulation enables the application of PureTemp product as a renewable energy resource in a wide range of industries, including automotive, construction and packaging. Hence, Encapsys modifies each microencapsulated PureTemp PCM to fit the production stage and end use application.
Eric Lindquist, CEO of Entropy Solutions, commented that the ability to provide commercial scale encapsulation in various cover materials creates an unbelievable range of consumer and commercial applications of PureTemp phase change material. Lindquist added that several leading companies across the world are developing new products ranging from medical devices to refrigeration systems that employ microencapsulated PureTemp product.
The worldwide PCM market is expected to reach $1.5 billion by 2015 and collaboration of Entropy Solutions and Encapsys enables both the companies to achieve a considerable portion of that growth. Microencapsulated PCM will allow companies to solve several issues related to thermal energy, concluded Lindquist.
