Smart Molecule heat performance technology

Solvay Advanced Polymers Llc : 06 November, 2016  (New Product)
Solvay has launched at K2016 the resin Technyl REDx, a new heat performance polyamide 6.6 (PA66) integrating a unique smart molecule self-reinforcement technology. This innovative material is aimed at demanding thermal management systems, especially in the automotive industry.

Solvay’s Technyl product range helps meet growing demand for downsized engines that continue to offer lightweighting performance and power output. Its metal replacement capabilities, offering fire, thermal and chemical protection, help the automotive industry to continuously reduce vehicle’s ecological footprint and CO2 emissions.

“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. “There is a need for new materials which resist the higher continuous heat stress of new generation engines without compromising on costs and performance.”

To address this challenge, Solvay has developed Technyl REDx, a smart molecule material including a patented self-strengthening technology present in the polymer chain without affecting its structure. This brand new technology remains inactive during injection molding 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.

Technyl REDx can be processed at energy-saving mould temperatures below 100°C, allowing simple and cost efficient manufacturing. Ageing tests over 3000 hours at 220°C demonstrate very high retention property as well as tensile property gain of more than 50 percent, without degradation of elongation at break.

“By providing long-term thermal stability, superior processability and excellent surface aspect, Technyl REDx opens up completely new possibilities for high-heat applications with lower material and manufacturing costs,” explains Antoine Guiu, Technyl REDx Project Leader. “Intrinsically heat-friendly, Technyl REDx eliminates the need for heat shields that may be required when using conventional materials.”
