TECHNYL® STAR - the high flow polyamide for metal replacement

Innovation in plastics and nylon is opening up a range of high-performance solutions that offer an excellent alternative to metal in many applications in automotive, consumer goods and industrial sectors. DOMO’s TECHNYL® range of metal replacement materials deliver technical properties that match or surpass those of metal parts, with the advantages of lighter weight, lower cost and nearly limitless design potential.  

A standout performer in this array of engineered materials, TECHNYL® STAR is a high flow polyamide that combines excellent mechanical performance, high strength and incomparable processability. A benchmark for high flow polyamides for metal replacement, in 2022 TECHNYL® STAR celebrates 20 years of giving manufacturers the ability to push the boundaries of product innovation. Switching from steel and other metals to this lightweight, high impact resistance thermoplastic is not only a valid technical option, but a quality choice that will differentiate your product. 

Key benefits of TECHNYL® STAR high flow polyamide

  • High flow polyamide for easy processing and less cycle time 
  • High strength polyamide as a replacement for metal  
  • Injection molding process saves time, cost and energy in manufacturing  
  • End-of-life product recyclability 
  • Medium to highly reinforced grades 
  • Unique mechanical performance, rigidity and resistance 
  • Flame retardant grades (with numerous color options) 
  • Excellent surface aspect 

Meeting customer needs for high strength polyamides

Using TECHNYL® STAR high strength polyamide as a substitute for metal not only reduces weight, but also reveals a new vista of design flexibility to let ideas take shape. From design to delivery, customers benefit from streamlined processes and lower costs, while offering their OEM and end-user customers the quality they expect. 

TECHNYL® STAR’s superior flowability makes the polymer easy to process, with excellent surface aspect, while providing outstanding mechanical performance. This is a big differentiator from the competition, giving manufacturers the ability to take their product innovations into new dimensions.  

The high flow polyamide simplifies the entire production process. Not only do plastics processing tools cost less and last longer than their industrial metal counterparts, but equipment investment is also lower, and designs can be optimized to require fewer raw materials. Moreover, using TECHNYL® STAR to replace metal enables manufacturers to reduce the number of tools and components required for production. Complex shapes can be produced in a single operation, with fewer parts, thus optimizing assembly processes, improving overall quality and speeding time to market. 

TECHNYL® STAR offers a complete array of high impact resistance polyamide metal replacement solutions – from the medium-reinforced TECHNYL® STAR S and AF for superior processing and molding efficiency, to highly-reinforced TECHNYL® STAR SX and AFX for exceptional weight reduction and rigidity.  

Why you should choose TECHNYL® STAR

Compared to standard PA6 or PA66, TECHNYL® STAR provides: 

  • Minimum 10% reduction in injection cycle time 
  • 20% decrease in injection pressure 
  • Clamping force reduction of 30% and a processing temperature reduction of 40˚C 
  • Up to 45°C melt temperature reduction 
  • Up to 60% more flowability  
  • Improved weld-line resistance (+70%) 
  • Lower internal stress in part 
  • Lower maintenance costs and tool wear 

Key applications of high impact resistance polyamides

In the automotive sector, OEMs need innovative manufacturing materials to meet the latest market demands and requirements, and the high strength polyamide TECHNYL® STAR is the right choice for metal replacement in automotive applications. These include cylinder head covers and engine covers, as well as turbo system applications in the powertrain, the steering wheel switch control, transmission parts and accelerator and clutch pedals,  electrical & electronics devices, such as connectors, and structural and internal & external parts, such as interior trim and switches and external door handles, plus much more. 

In the electrical and electronics sector, too, TECHNYL® STAR polymer grades complement the company’s electric-flow solutions with halogen-free flame retardant (HFFR) features and certified electrical protection in combination with optimized high fluidity. Notably, the high flow polyamide is widely used for metal replacement in an array of components for renewable energy and photovoltaic applications, including junction boxes, diode holders and module mounts.
