At the recent K Show in Düsseldorf, Germany, Solvay launced Technyl REDx, a new heat performance polyamide (PA) 66) integrating a unique “smart molecule” self-reinforcement technology.

The 35% glass fibre-reinforced material reportedly outperforms conventional specialty polymers in demanding thermal management systems, especially in the automotive industry.

“Today, more than 12 million engines use Technyl heat performance technologies. Our materials enable car manufacturers to overcome engine downsizing constraints, such as greatly increased temperatures and pressures,” says Dr James Mitchell, Global Automotive Market Director for Solvay Engineering Plastics.

However, “There is a need for new material solutions which resist the higher continuous heat stress of new generation engines without compromising on costs and performance,” he notes.

To address this challenge, Solvay developed Technyl REDx, a smart molecule material including a patented self-strengthening technology present in the polymer chain without affecting its structure.

This new technology remains inactive during injection moulding of car parts, leaving the material behaving like a high-flow PA66.

During the vehicle’s use, the elevated temperatures activate the smart technology, leading to rapid cross-linking that boosts the mechanical properties far beyond their initial values.
