(Bonneuil-sur-Marne, France) has developed a microencapsulation technology and process to produce what the company says are the first sealed, process-resistant and customizable microcapsules. According to Calyxia, this technology expands the performance potential and the scope of use of specialty chemicals.

Calyxia says its technology can protect reactive, functional and optical additives even in extreme temperature and shear processing conditions (extrusion, injection, compression molding, film casting).

More specifically, Calyxia technology can protect process additives (catalysts, accelerators, curing agents) from premature reaction during processing, and then deliver the additive on command during curing. This reportedly provides a significant advancement in terms of process and performance control. In addition, the Calyxia technology can protect functional additives (anti-wear, anti-abrasion) against degradation, cross-reaction or instability during processing. Anti-wear/abrasion additives are then delivered only in the event of wear or abrasion. Calyxia says functional additives enhance both the performance and the lifetime of the final product. Calyxia’s microencapsulation technology is also able to fully protected optical additives (pigments, liquid crystals, dyes) throughout the lifetime of the product.

Calyxia says its microencapsulation technology has been successfully validated with many large actors in high-performance plastics, electronics materials, adhesives and coatings applications to provide new features to  materials or improve the performance of current materials.
