PCM briefing: Croda merger talks reported; RAL PCM members to meet March 1

Ben Welter - Monday, February 12, 2018

• British specialty chemicals maker Croda International Plc has held unsuccessful talks with Ashland Global Holdings Inc. about a possible merger, a source familiar with the matter told Reuters last week.

Croda recently redesigned the CrodaTherm website, www.crodatherm.com. The new site offers improved navigation and searchability, a wider range of potential PCM applications and profiles of the CrodaTherm technical team. Visitors can register to log in and download datasheets and order samples. "We are excited to launch this new website, making it even easier for our customers to find us and the products they need," said Graeme Tweddle, global managing director for energy technologies at Croda.

• Members of the RAL Quality Association PCM, a European-based organization established in 2004 to develop standards for the phase change material industry, will meet in Düsseldorf, Germany, on March 1. On the agenda: Quality and testing specifications; improvements to the association's website; member content on the BUILD UP Web portal; promotion of PCMs in the European Union, Germany, Netherlands and the United States; and registration of RAL quality marks.   

Sonoco ThermoSafe is accepting registrations for the company's first Leading Minds Seminar, to be held June 6-7 in Philadelphia. Co-hosted by ELPRO, the seminar is a chance for pharmaceutical manufacturers, supply chain partners and government representatives to discuss temperature-assurance packaging and data monitoring in a collaborative environment. Day two includes a visit to ThermoSafe's design and testing lab in Montgomeryville, Penn.

Sonoco is No. 90 on Barron's inaugural list of "The 100 Most Sustainable Companies." 

• A "measurement and verification study" of a Viking Cold Solutions TES system installed in a 320-square-foot walk-in freezer at a supermarket in Fremont, Calif., showed an 18 percent net reduction in energy consumption.   

• The deadline is Monday, Feb. 12, to submit a concept paper for ARPA-E's OPEN 2018 competition. Up to $100 million is available for new projects that "transform the way we generate, store and use energy."

DLR Group, which part of a public-private collaboration working to develop PCM-based cooling and heating methods for Agua Fria Canyon View High School, has been named one of Arizona's "40 Companies to Watch" in 2018 by AZRE magazine. 

• Entries are being accepted for Bio-Based World News' 2018 Innovation Awards. The four categories are product of the year, chemical innovation of the year, best use of alternative feedstocks and industry story of the year. The entry deadline is Feb. 23. Winners will be honored March 20 at the World Bio Markets conference in Amsterdam. 

• Nantucket, Mass., has approved the installation of an Ice Bear thermal storage and air-conditioning unit in a building owned by the town. Last summer, Genbright won a $1.5 million grant from the state to install the units in more than 200 Nantucket homes, with the goal of reducing peak energy demand and staving off the need for a third undersea power cable for the island. But some residents voiced skepticism about the technology, prompting the town board to approve the test installation.

• Shippers have found that cocoa butter can be hard to contain on long ocean voyages. There have been reports of the material leaking out of containers as it changes phase, clogging bilges and generally making a mess. The Cargo Incident Notification System, established in 2011 to share information on all cargo-related incidents, has issued guidelines that recommend the material be shipped in refrigerated containers, particularly when passing through hot climate zones.

So, which PCM product idea was phony?

Ben Welter - Monday, January 08, 2018

In 2017's final issue of Phase Change Matters, we challenged readers to identify which of these PCM product ideas was phony: an edible additive for chocolate, a feminine pad with cooling properties, a cooling pad for chickens, a thermally responsive bra and a temperature-controlled shipping container for mosquito eggs. 

It was a trick question: All five product ideas were serious inquiries submitted to Entropy Solutions in the past year. Thanks to Holger Böhme, Shaun Mann and Kosheela Poo Palam for submitting answers - and for subscribing to our newsletter. Each will receive a PureTemp temperature-control coffee tumbler.

U.S. patent application 9828165 (applicant Sonoco Development Inc., Hartsville, S.C.):

"A thermally insulated VIP sandwich shipper for a temperature sensitive payload is provided. The shipper comprises an outer shell, an inner shell and vacuum insulated panels sandwiched therebetween. The outer shell and the inner shell may be unitary rigid structures made of an expanded foam material and comprising a bottom having a perimeter and sides extending from the bottom perimeter and terminating in a rim. The inner shell rim may be spaced from the outer shell rim to define a gap, the gap being sealed to create an enclosed space within which the vacuum insulated panels are located. Each vacuum insulated panel may be oriented substantially orthogonally to at least one adjacent vacuum insulated panel and have an edge that abuts the adjacent vacuum insulated panels."

The UV-activated thermal energy storage material shows the rapid crystallization and heat discharge upon visible light (blue LED) illumination. (Grossman Group at MIT)MIT researchers have combined conventional phase change material with an organic compound that responds to a pulse of light. "The new system," MIT News reports, "uses molecular switches that change shape in response to light; when integrated into the PCM, the phase-change temperature of the hybrid material can be adjusted with light, allowing the thermal energy of the phase change to be maintained even well below the melting point of the original material." The system could be used in a thermal battery to store heat from the sun or any other source and release the heat when needed.

Stanford University researchers have developed a reversible fabric that keeps skin a comfortable temperature whatever the weather. "On one side," Stanford News reports, "a copper coating traps heat between a polyethylene layer and the skin; on the other, a carbon coating releases heat under another layer of polyethylene." The fabric can either warm or cool the wearer, depending which side faces out.

• Scientists investigating how scavenging animals are adapting to the monoculture palm oil plantations in Borneo were surprised by what turned up in their traps. "In the jungles and border regions, the team found animals such as civets, otters, mongooses and pigs," Oils & Fats International magazine reports. "But the closer they got to the plantations where the land had been disturbed and human activity was frequent, the fewer species they found until only one stood out – the Southeast Asian water monitor." The big lizards are thriving, thanks to a plentiful supply of food and less competition from mammalian scavengers and predators.
