Promyde PA6 and PA66 FR compounds range offers unreinforced and reinforced grades with different up to 50% fiber content, with mineral fillers or other reinforcement charges. Our entire range is also available in colored products.

We offer solutions for all flame-resistance levels , from the most basic V2 up to V0 classification in UL94 for the most demanding applications and a Glow Wire Flammability Index (GWFI ) up to 960°C. These excellent flame retardant properties cover all the requirements of E&E applications. In addition, we have in a portfolio grades that meet the maximum safety level required by the EN45545 standard for Railway Fire protection. 

Promyde offers a wide range of halogen-free products, in which safety prevails, but now provide a reduced toxicity and have a lower environmental impact. 

Promyde Flame retardant compounds main advantages:

  • High durability. Strength & resistance for housings and protective parts
  • Optimal flame-resistance and a high temperature resistance 
  • Available grades that meet the highest standards in the market such as V0 in UL94 y HL3 by  EN45545 standard
  • Halogen-free flame retardant technology


The Terylene PBT, PET and PBT/PET product range offers unreinforced and glass fiber reinforced grades with properties that achieve the highest values ​​of flame-resistance: V0 and V2 UL-94, with a Glow Wire Flammability Index (GWFI) of 960ºC. These values ​​are reached even below 1mm thickness.

Our entire range of PBT, PET and PBT/PET compounds products is also available in colors.

Terylene also offers its halogen free range.
