Alexium International Group Ltd., a leader in advanced phase-change material systems and flame-retardant chemistries, has acquired Microtek Laboratories from CAVU Group, expanding Alexium’s thermal-management platform and including Microtek’s full microencapsulation and PCM business and associated intellectual property.
Microtek’s temperature-controlled packaging division, Adaptek™, is excluded from the transaction and remains under CAVU Group ownership.
The acquisition brings together two of the industry’s most established innovators in microencapsulation and PCM chemistry. According to a release, integrating Microtek’s state-of-the-art manufacturing plant, formulations, and decades of encapsulation expertise into Alexium’s vertically integrated U.S. operations enhances domestic production capability, strengthens supply-chain resiliency, and expands the combined technology portfolio.
“Bringing Microtek’s microencapsulation and PCM technologies—and their manufacturing facilities—into the Alexium family accelerates our ability to deliver high-performance cooling solutions with unmatched reliability,” says Billy Blackburn, CEO of Alexium International. “This acquisition broadens our technical capabilities and meaningfully strengthens our U.S. supply chain, benefiting both Microtek and Alexium customers with greater stability, responsiveness, and scalability. We intend to continue operations in Dayton and to serve Microtek’s existing customer base without any interruption.”
Microtek Laboratories has long been recognized as a pioneer in microencapsulated PCM technologies, serving markets including bedding, apparel, building materials, and industrial applications. Its processes, formulations, IP, and flagship NexTek™ and Micronal® product lines complement Alexium’s existing portfolio, including BioCool®, Alexicool®, DelCool™, AlexiShield, and Eclipsys®, creating a more comprehensive platform for foam, textile, and specialty materials manufacturers.
“Alexium is an outstanding strategic fit for Microtek’s PCM and encapsulation business,” says Tim Riazzi of CAVU Group. “Their U.S. manufacturing strength, technical depth, and customer-centric approach ensure Microtek’s technologies will continue to grow, scale, and deliver value to the markets we’ve served for more than three decades.”
