TECHNYL® MAX - Glass fiber reinforced polyamide for metal replacement

DOMO Engineered Materials is dedicated to developing new products for metal replacement for the automotive industry with improved strength, stiffness and fatigue performance. TECHNYL® MAX, a high glass fiber reinforced polyamide, or nylon, is a game-changer for metal replacement, thanks to its rigidity, fatigue resistance, weight reduction properties and dimensional stability. These best-in-class attributes make TECHNYL® MAX ideal for structural applications both in the latest internal combustion engine (ICE) platforms as well as for alternative drive technologies, like electric vehicles (EV).  

Key benefits of TECHNYL® MAX glass fiber reinforced polymers

  • Rigid polymer: Weight reduction thanks to low density and extreme rigidity and toughness 
  • Fatigue polymer: Outstanding resistance to fatigue and high frequencies 
  • Robust polymer: Up to 60% glass filled for the highest mechanical performance 
  • Excellent surface aspect 
  • Easy processing 
  • Excellent part performance retention

Meeting customer needs for reinforced glass fiber polymers

TECHNYL® MAX glass fiber reinforced polyamide was created through the combination of the TECHNYL® STAR high-fluidity polymer – a reference in the industry – together with the latest glass fiber technology. This innovation results in a unique set of properties that makes TECHNYL® MAX the material of choice for metal replacement in the sector. Thanks to its stiffness, fatigue resistance and weight reduction properties, the nylon is also ideal for replacing PPA-GF, PA-LGF, PA-CF and other specialty compounds in structural parts. 

Why you should choose TECHNYL® MAX

  • Up to 65% glass fiber 
  • High tensile modulus (> 20 GPa) 
  • Massive warpage reduction 
  • Excellent dimensional stability 
  • Good melt flowability 
  • Reduced anisotropy 
  • Reduced effect of humidity 
  • Higher fatigue resistance than standard PA66 
  • Better dimensional stability than standard PA66 

Key applications of glass fiber polymers

The TECHNYL® MAX reinforced glass fiber polyamide solution targets structural components, such as transmission and motor mount cross beams, battery system mounts, air shutter grills and seat structures. Its low density offers significant weight savings over typical die-cast metals at comparable tensile strength. This is of particular importance for applications in EVs, which require even greater rigidity and fatigue resistance due to higher frequencies and cyclical load.  

In the internal combustion engine, making parts with engineering plastic materials, or nylon, has proven to be an important breakthrough, by reducing weight significantly without sacrificing performance. TECHNYL® MAX glass fiber reinforced polyamide is the metal replacement polymer of choice for components like the engine mounting, middle consoles gearbox support, throttle body and more. 

For automotive transmission parts, metal replacement materials must offer both rigidity and fatigue resistance to meet the needs of applications ranging from the powertrain mounting system, transmission cover and pedal systems. For safety-critical parts, such as brake pedals, TECHNYL ® MAX reinforced glass fiber polyamide is at the technology forefront, replacing the conventional steel design with a lightweight hybrid structure.  

Moreover, these advantages of the glass fiber reinforced polyamide, or nylon, for metal replacement have applications beyond the automotive segment. Sectors like consumer and industrial goods can also benefit from TECHNYL® MAX’s rigidity, fatigue resistance and weight reduction properties for mechanical supports and mountings, robotics components and other parts with high-end mechanical needs.
