Technyl RED

Producer: Solvay
Polymer type PPA

Material solution for thermally efficient engines. Technyl® RED is a new generation of PA66 that has been developed to resist the increasing continuous heat stress of new generation engines. 

Superior long-term heat performance up to 220°C.

General info

Polyamide Technyl® portfolio offers various solutions to thermally efficient engines: 

  • The established Technyl® HP range based on pure PA66 has been upgraded by Technyl® RED series, providing new solutions to OEMs to overcome the constraints related to engine downsizing, such as greatly increased temperatures and pressures. 
  • The “triple-six” PA66/6 based Technyl® RED A offers, next to a good heat ageing resistance comparable to Technyl® HP of 180°C (3000h) or 210°C (1000h) for long term heat exposure, high flowability and nice surface aspect, combined with excellent weld line strength.
  • The innovative Technyl® RED  X technology boosts the thermal ageing resistance and material strength of classical polyamide 6.6 by integrating a “smart molecule” providing a self-strengthening effect. This self-strengthening effect doesn’t require a specific activation temperature, but becomes effective already at rather low temperatures (e.g. 120 °C).
