PCM briefing: Alexium adds clients in bedding industry; new research on temperature-controlled pharma packaging

Ben Welter - Tuesday, June 07, 2016

Alexium International has announced an agreement to sell its new flame-retardant phase change material to a U.S.-based textile finisher serving the bedding industry. Alexium, based in Perth, Australia, and Greer, S.C., announced in May that it had reached a PCM sales agreement with one of the world's largest producers of mattress ticking. "Alexium is now in production or full-scale trials with six global mattress fabric finishers," said CEO Nicholas Clark "and for the first time, a major manufacturer in apparel is evaluating our flame retardant phase change material technology."

TheM dining mat• Months after falling short of raising $30,000 on IndieGoGo, developers of a PCM-powered thermal dining placemat called TheM said in January that they hoped to develop a successful design by the end of February. The team is now apologizing again, telling backers: "The PCM material did not work as intended and [we are] trying to develop a solution that can still add value to the innovation. Please bear with us and within the next 60 days [we hope] to have a product with which [we] can reward your support and patience."

Ira Smith, director of strategic development for global transport and biologistics at Pelican BioThermal, is among the panelists at the FlyPharma conference in Brussels this week. The topic: The increasing appeal of inter-continental rail freight services and sea freight.

Glacier Tek cooling vests are profiled in the June issue of OR Today magazine. The vests, which use PureTemp bio-based phase change material to maintain thermal comfort, are being marketed as a way to address heat stress among surgeons and operating room staff, who endure "bright lights, sterile gowns, lead aprons, physical exertion and time stress."

GreenCE is offering a free hourlong webinar, "Reinventing Green Building: Focus on Carbon & Leverage Technology," at 1 p.m. June 14. Instructors will discuss the limitations of LEED certification in various U.S. market segments and identify alternatives to LEED certification.

Monodraught's Cool-Phase cooling and ventilation system has been specified for Harrogate's new civic headquarters, now under construction in County Durham, England. The system combines a phase change material thermal energy store with an intelligently controlled air handling unit to actively ventilate and cool buildings without the use of refrigerants. The company says the system contributes credits toward BREEAM standards for lifecycle costs, indoor air quality and low- and zero-carbon technologies.
