TECHNYL® RED - Take on the heat with thermal resistant polyamides

The automotive industry continues to push the envelope when it comes to improving powertrain technology to meet increasingly stringent standards. In this relentless pursuit to enhance efficiencies and squeeze more power out of lighter engines, carmakers are seeking innovative metal replacement solutions capable of withstanding high temperatures. DOMO Engineered Materials’ TECHNYL® RED line of heat resistant polyamide, or nylon, solutions are specifically designed to resist the higher continuous heat stress of the latest-generation internal combustion and hybrid engines.  

The TECHNYL® RED range of heat resistant polyamides are designed especially for automotive applications operating at continuous temperatures between 200°C and 220°C. This line of latest-generation high temperature resistant thermoplastics helps OEMs and tier suppliers to reach new levels of performance with their turbo system parts in high performance engines.  

Key benefits of TECHNYL® RED heat resistant polyamides

  • High temperature performance even at 200°C (RED S)/220°C (RED J) 
  • Maintains 50% of its initial properties up to 2000h at 200°C (RED S)/3000h at 210°C (RED J) 
  • Superior strength after aging 
  • High chemical resistance to acid condensate 
  • Superior oil resistance 
  • High flowability and PA66-like processing 
  • Great surface aspect 
  • Very good welding ability with both vibration welding  
  • and hot gas welding technology 
  • Best-in-class price/performance 
  • PPA replacement 

Meeting customer needs for high temperature polyamides

The entire TECHNYL® RED thermoplastic line-up provides flexible solutions for heat-resistant parts in automotive and industrial applications, with an attractive cost/performance ratio compared to metals and alternative plastics. With mechanical functionality and chemical composition adapted for cooling system designs, the recommended melt and mold temperatures are significantly lower than for competitive PA4.6 or PPA resins, which saves energy during processing and minimizes part cooling time.   

With its innovative formulation, TECHNYL® RED S provides numerous benefits, such as strong impact and corrosion resistance, high flowability, superior surface aspect and excellent weldability. This PPA replacement nylon is designed to resist continuous high operating temperatures up to 210°C (at 1000h) or 200°C (at 2000 hours). 

Based on patented PA66/6T technology, TECHNYL® RED J flows like PA66, ensures high chemical resistance and excellent surface aspect, while offering outstanding long-term heat aging performance at up to 220°C (at 2000 hours) or 210°C (at 3000 hours). In addition, it is well-suited for both vibration and hot gas welding, delivering high burst pressure levels confirmed in extensive pulsated air pressure tests at DOMO’s Application Performance Testing (APT®) centers.  

Why you should choose TECHNYL® RED

  • TECHNYL® RED S maintains its strength at continuous temperatures up to 200°C for 2000h  
  • TECHNYL® RED J can handle up to 210°C for 3000h 
  • TECHNYL® RED J can handle up to 220°C for 2000h 

Key applications of TECHNYL® RED heat resistant polyamides

The TECHNYL® RED line of heat resistant polyamides are designed for engine components operating above 200°C, including the challenging high-temperature requirements of turbo-charged engines. They deliver superior thermal aging stability without compromising performance or cost-efficient processability. 

TECHNYL® RED S is a heat-stabilized polyamide, or nylon, designed especially for automotive applications operating at a continuous temperature of 200°C, such as turbo air ducts, charge air coolers and cylinder head covers.  

TECHNYL® RED J is designed to add significant additional heat performance capability at temperatures up to 220°C. It targets applications such as air intake manifolds with integrated water charge air cooler, resonators, cylinder head and engine covers, as well as water charge air coolers and turbo air ducts.   

The TECHNYL® RED line of high temperature polyamides enable manufacturers to optimize parts design and functional integration, while reducing weight significantly. More than 15 million engines rely on TECHNYL® thermal management technologies.
