Engineering the future of high-performance materials.
Alexium develops phase change, flame retardant, and humidity-management chemistries that transform how the world's most demanding products perform.
Phase Change Material microcapsules
Enhanced view from a compound microscope
Six technologies. Endless applications.
Our chemistry platform spans thermal regulation, fire safety, and moisture control — purpose-built for formulators and OEMs.
Phase Change Materials
Microencapsulated PCMs that absorb and release thermal energy on demand.
Flame Retardant Materials
Durable, formaldehyde-free FR chemistries for textiles and uniforms.
Perpetual Cooling
Long-lasting cooling through active thermal management (Eclipsys®) and humidity management (DelCool™) — used independently or stacked.
Humidity Management
Engineered moisture control for comfort and material integrity.
Predictive Thermal Profile
Computational modeling that forecasts in-product thermal behavior.
Testing Capabilities & Claim Validation
Full-spectrum lab and pilot testing for thermal, flame, and humidity.
From molecule to market.
Following our acquisition of Microtek Laboratories, Alexium is now the world's most vertically integrated developer of microencapsulated phase change materials and FR chemistries — covering everything from raw synthesis to finished-product validation.
- Proprietary microencapsulation IP and manufacturing
- Application labs for textiles, foams, and coatings
- Custom formulation services for OEM partners
