Alexium International, a leader in advanced thermal management solutions, has announced a breakthrough in phase change material technology. Independent testing confirms that BioCool® formulations have achieved verified testing of a latent heat of fusion (enthalpy) exceeding 200 Joules per gram.
This milestone positions BioCool as the highest-capacity formulated PCM currently available on the market.
“Reaching the 200 J/g threshold changes the equation for product designers,” says Nick Leitner, vice president of technology at Alexium. “It means manufacturers can either deliver significantly more cooling power without increasing weight, or they can maintain current cooling levels using far less material, improving cost-efficiency and product feel.”
The new BioCool formulation also features an enhanced recrystallization rate, allowing the material to recharge faster and more efficiently than conventional alternatives. This dual-advantage capability addresses the two biggest challenges in the thermal regulation industry: the duration of cooling and the speed of recovery.
According to a release, the BioCool formulation has been engineered with an optimized nucleating profile that accelerates recrystallization. This ensures that the material returns to its cooling state more rapidly during ambient temperature drops, making it ready for the next heat cycle sooner. This is a critical advancement for applications like bedding, where “thermal saturation” (the material stopping working halfway through the night) has historically been a consumer complaint.
