Microencapsulated PCM Technologies
The pinnacle of thermal management — actively absorbing, storing, and releasing heat across diverse applications.
Alexium's microencapsulated phase change materials (mPCM) actively regulate temperature by absorbing, storing, and releasing thermal energy — delivering superior comfort and performance across textiles, bedding, apparel, and consumer products.

Four platforms, one core competency
Nextek™ delivers patented, economical thermal stability with robust capsule walls. Vivtek™ pairs that same durability with a bio-based core sourced from agricultural feedstocks. EcoTek adds a biodegradable microcapsule that has passed OECD 301F testing — durable in use, biodegradable at end of life. Micronal is the comfort-range mPCM historically trusted by BASF, offering precise human-comfort melt points for building, bedding, and apparel applications. Across the portfolio, melt points span 6°C to 43°C.
Built into buildings and data centers
The same microcapsules mix into gypsum board, plaster, aerated concrete, ceiling cassettes and coatings, turning the building itself into latent thermal mass. In data centers and other critical facilities that buffers daily peaks in support spaces, adds capacity behind data hall walls and ceilings, and gives lightweight modular construction the heat-storage capacity of far heavier materials — alongside chilled-water storage and UPS-backed cooling, not instead of it. We also co-develop slurries, plates and cassettes at custom melt points for active thermal storage.
