Glacier Tek adds flexible PCM microspheres to new line of cooling packs

Ben Welter - Monday, July 15, 2019

Glacier Tek LLC of Minneapolis has incorporated flexible PCM microspheres in the cooling packs used in its Flex Vest line of cooling vests. 

Glacier Tek's new cooling packsThe cooling packs, redesigned for improved comfort and performance, feature a soft, durable nylon shell. They reach a flexible state more quickly and feel colder than the previous packs. 

The Flex Vest is designed to maintain a comfortable microclimate of 18 degrees C for up to 2.5 hours. The new packs can be recharged in about 30 minutes in ice water or two hours in a refrigerator. But they are most effective when fully solidified in a freezer, which takes about an hour. The cooling packs weigh about 164 grams each and fit into 12 pockets inside the vest.

The novel cooling material, developed by PureTemp LLC of Minneapolis, is composed of a biobased phased change material. It is similar to the material used in the Glacier Tek therapy cooling packs introduced at the American College of Sports Medicine trade show in Orlando in May.

"PureTemp is excited to bring this shape-stabilized PCM format to the market," said Chris Servais, vice president of operations at PureTemp. "Glacier Tek has capitalized on its unique and improved characteristics.”
