PrimaLoft develops Cross Core with up to 90% recycled content
Insulation maker PrimaLoft is boosting the post-consumer recycled content in its PrimaLoft Cross Core Series – with one version increasing from 35% to 90%.
The Cross Core platform fuses PrimaLoft fibres with aerogel, a highly porous, lightweight structure that is composed of more than 95% air.
Vanessa Mason, PrimaLoft’s senior vice-president of engineering, insulation and polymers, said: “When we first began experimenting with the idea of using aerogel in insulation fibres, our focus was on getting the formula right so that we were delivering a new level of thermal performance.
“Once we became the first to crack that code, we knew we needed to continue to innovate on the sustainability side and find a way to use as much recycled content as possible, while maintaining that performance.”
Available from autumn, PrimaLoft Gold Insulation with Cross Core technology blends PrimaLoft Gold Insulation with aerogel, using 90% post-consumer recycled material, up from 35% in the previous version.
The stretch version now includes 5% stretch and 70% post-consumer recycled content.
PrimaLoft Gold Insulation Hi-Loft Ultra with Cross Core, for use in puffier jackets and sleeping bags, is available with 74% post-consumer recycled material.
PrimaLoft Silver Insulation ThermoPlume with Cross Core offers up to 12% more warmth compared with previous ThermoPlume insulation and includes a water-repellent finish.
Brands using the Cross Core series include Mammut, Vaude, La Sportiva, Millet, Bergans, Haglöfs, Norröna, Montane and Patagonia.
