Entropy Solutions partners with Encapsys to microencapsulate its PureTemp phase change material


Strategic partnership allows Minneapolis-based technology company to incorporate PureTemp material in an array of new applications.

MINNEAPOLIS, Minnesota — Entropy Solutions, Inc., a bio-based specialty company, today announced a strategic partnership with Encapsys, a business unit of Appleton Papers Inc. Encapsys applies microencapsulation — the process of encasing a core material with tiny shells or capsules that are microns in diameter — to Entropy Solutions’ 100 percent renewable based PureTemp phase change materials (PCM). PureTemp is a thermal energy storage technology that captures, stores and reuses otherwise lost or wasted energy to maintain constant temperatures for extended periods of time.

“This partnership solves the biggest challenge facing phase change material users today, which is robust and reliable containment. Being able to offer commercial scale encapsulation in a variety of cover materials opens up an incredible array of consumer and commercial product applications of PureTemp,” said Eric Lindquist, Chief Executive Officer of Entropy Solutions. “Some of the world’s leading companies are developing innovative new products which incorporate microencapsulated PureTemp into everything from medical devices to HVAC and refrigeration systems.”

Microencapsulation is the key to applying PureTemp as a renewable energy resource across different industries, including packaging, construction and automotive. To allow for such a variety of applications, Encapsys tailors each microencapsulated PureTemp product to fit the manufacturing process and end use application.

“Our partnership with Entropy has enabled us to expand into a growing market which can benefit from the breadth of Encapsys’s microencapsulation technologies,” said Irenée Philippe, Group Business Manager for Encapsys. “We are excited at the prospect of expanding upon our success in developing and commercializing microencapsulated solutions for consumer and industrial products to include microencapsulated PureTemp. The combination of our technologies and knowledge produces game-changing options for end-markets.”

Derived from 100 percent sustainable sources, PureTemp is engineered to maintain more than 200 different transition temperatures with consistent, repeatable performance. It can be permanently encapsulated in virtually anything at nearly any temperature, while other PCMs are limited by temperature ranges and containment methods.

“The global PCM market is estimated to grow to $1.5 billion by 2015, and our partnership with Encapsys positions both companies to realize a significant portion of that growth,” Lindquist said. “Microencapsulated PCM will enable companies to solve many types of thermal energy related issues.”
