Meeting customer needs for halogen-free polymers

TECHNYL® ONE, the halogen-free high temperature polyamide specifically formulated for electrical protection devices and power management equipment, empowers manufacturers to push the limits of miniaturization in the industry. With excellent electrical performance, molding options, and mechanical and tensile strength, TECHNYL® ONE solutions have demonstrated their value in numerous product designs. The halogen-free polymer combines peak mechanical and electrical properties with superior flowability so manufacturers can create smaller and more complex parts to optimize design without compromising on safety. 

With its wide processing window, accurate filling and good surface aspect, the TECHNYL® ONE halogen-free high temperature polyamide delivers robust results. At the same time, the low corrosion polyamide meets production challenges without any drawbacks for tools or injection molding machines. TECHNYL® ONE is significantly less corrosive than traditional halogen-free flame-retardant materials, further helping to increase production equipment lifetimes. 

With an industry-leading certification portfolio, the TECHNYL® ONE halogen-free polymer meets the strictest regulations facing the electrical equipment market, notably UL and IEC fire and fume certification. This includes: 

  • UL94 V0 rating at a wall thickness of only 0.4 mm 
  • Railway standard EN 45545-2: HL3 under R22 & R23 
  • A fully compliant yellow card, including RTI and rating @0.4mm 
  • Compliance with EU environmental waste management directives, RoHS1 2002/95/CE and WEEE2 2002/96/CE 

Why you should choose TECHNYL® ONE

  • Yellow card available with the highest RTI rating at 150°C, at 0.4mm wall thickness 
  • High fire rating class: UL94 at 0.4mm, 600V CTI, GWFI 960°C at 0.8mm 
  • High melt temperature of 285°C and a high crystallization temperature of 250°C, which sets it apart from standard PA66, not to mention PPA
