Alexium adds Micronal to global PCM platform

Alexium International Group Limited said June 29, 2026, that it has integrated the Micronal technology portfolio into its phase change material platform after acquiring Microtek Laboratories. The move expands Alexium’s manufacturing, formulation and application support as demand grows for broader thermal management solutions across textiles, bedding and industrial uses.

Why it matters: - Alexium said the Micronal integration strengthens its vertically integrated thermal management platform and broadens the company’s ability to serve multiple end markets. - The expansion is aimed at customers that want application-specific cooling and thermal regulation, not generic cool-to-the-touch materials. - The move also adds domestic supply chain capacity, which can improve consistency and speed for customers.

What happened: - Alexium International Group Limited announced the continued expansion of its global phase change material platform on June 29, 2026. - The company integrated the Micronal technology portfolio into its PCM platform after its acquisition of Microtek Laboratories. - The acquisition gave Alexium ownership of the Micronal intellectual property portfolio and related PCM technologies. - Alexium said the integration expands capabilities across coatings, foams, laminates, fibers and textile applications. - The company said Micronal is now part of its broader innovation ecosystem.

The details: - Micronal is a microencapsulated PCM technology platform that has been used in textiles and thermal management applications. - Alexium said the expanded platform gives customers more formulation flexibility, domestic manufacturing capabilities and application development support. - The company’s portfolio now includes Micronal, NexTek, VivTek, AlexiCool and BioCool. - Micronal is positioned for use in textiles, mattresses, building materials, construction, performance and comfort apparel, and industrial applications. - NexTek is aimed at formulators seeking high thermal effusivity. - VivTek is aimed at formulators seeking high cooling capacity with a sustainability story. - AlexiCool is a formulated coating designed for mattress systems, foam applications and system-level thermal regulation. - BioCool is a formulated coating supporting bio-based thermal management solutions. - Alexium said future next-generation technologies are under development, with a focus on sustainability and advanced encapsulation architectures. - The company said its in-house testing, formulation and predictive modeling tools help evaluate PCM performance across complete systems. - Alexium recently introduced its Predictive Thermal Profile platform to model thermal regulation across multi-layer product constructions. - For more information about Alexium’s thermal management technologies, visit Alexium’s website.

Between the lines: - The announcement signals a shift from single-material cooling claims to full-system thermal design. - Billy Blackburn, Alexium’s CEO, said the company is building on Micronal’s market recognition with expanded manufacturing, vertically integrated development and next-generation innovation. - Blackburn also said brands are looking for longer-duration cooling, better thermal regulation, manufacturability and end-user comfort.

What's next: - Alexium said the expanded platform will support continued collaboration with customers on thermal management strategies. - The company is positioning its PCM portfolio for bedding, performance apparel, footwear, protective textiles, industrial materials and technical textile markets. - Alexium said the integration reinforces its long-term focus on innovation in advanced thermal management materials.

The bottom line: - Alexium is using the Micronal acquisition to turn a broader PCM portfolio into a more integrated thermal management business with wider application reach and stronger manufacturing support.
