Sonoco ThermoSafe's new Via Blood Transporter features PureTemp PCM

Ben Welter - Friday, June 19, 2015

Sonoco ThermoSafe has introduced a new reusable container for the transport and temporary storage of red blood cells and platelets. 

Via Blood TransporterThe Via Blood Transporter maintains red blood cells at 1-6° Celsius for eight hours during transport and 1-10° C for the temporary storage of blood product for a minimum of 12 hours. The container is made of expanded polypropylene and features PureTemp biobased phase change material.

“The Via Blood Transporter was designed in accordance with blood bank user feedback,” said Marianne Hoonakker-Kelly, Sonoco ThermoSafe business development and market manager.  “Unique and innovative features such as the front platelet pouch and affixed assembly instructions not only promote compliance, transport efficiencies and minimized risk of loss due to mishandling – they ultimately promote patient safety. Given the cost pressures applied to health care systems, products like the Via Blood Transporter are critical as they ensure recommended temperature protection while preventing the waste and loss of valuable blood product.”

PCM market projected to reach $339 million in the Americas by 2019

Ben Welter - Thursday, April 09, 2015

The market for advanced phase change materials in the Americas will reach $339.56 million by 2019, according to the latest report from MicroMarket Monitor. That's a compound annual growth rate of 19.9% from 2014 to 2019. The report identifies the shipping, packaging and refrigeration segment as a key driver and attributes much of the growth to initiatives by the Emerging Technologies Coordinating Council, the National Renewable Energy Laboratory and other bodies.

MicroMarket Monitor is planning to release similar reports next month on the PCM markets in Asia-Pacific and Middle East-Africa. The Asia-Pacific market is expected to see a compound annual growth rate of 19.2 percent from 2013 to 2018. The Middle East-Africa market is expected see a CAGR of 11.9 percent in the same period.

Steep growth projected for Europe's organic PCM market through 2018

Ben Welter - Wednesday, April 08, 2015

The European market for organic phase change materials is projected to see a compound annual growth rate of 20.4 percent from 2013 to 2018, according to the latest report from MicroMarket Monitor. Organic PCMs fall into two categories: paraffins (derived from petroleum) and fatty acids (derived from animal fat and plant oils). The report, to be released May 2, attributes much of the growth to new government rules aimed at reducing the emission of greenhouse gases.
