Japan's DKS Co. has developed a bio-based material derived from #trehalose that functions as a processing aid for engineering plastics molded at temperatures up to 300°C. The additive enhances optical properties while simultaneously improving plastic performance and reducing environmental impact through bio-based raw materials.

#DKS is currently shipping samples for #hightemperature molding applications, including #automotiveinterior materials, #housings, and connectors for #electronicdevices.

Trehalose outperforms sucrose in heat resistance

Plastics used in automobiles, electronic devices, and industrial components rely on various additives to enhance functionality. While DKS has traditionally focused on sucrose-based derivatives for gloss enhancement, hydrophilization, and antistatic properties, these materials sometimes lacked sufficient heat resistance for high-temperature molding applications, resulting in decomposition and discoloration.

DKS identified trehalose as a superior alternative due to its higher heat resistance and chemical stability, successfully developing a new trehalose derivative for plastic applications.

Superior stability under extreme conditions

Trehalose is a highly stable, non-reducing #disaccharide found in nature with excellent #heatresistance and chemical stability. Compared to conventional sucrose-based materials, this derivative suppresses decomposition and discoloration under high-temperature molding conditions, making it ideal for engineering plastics requiring elevated processing temperatures.

As a modifier, the trehalose derivative enhances processability by imparting fluidity to plastics and improves functionality through enhanced optical properties.
