Flame retardant for TPU

My answer is:

You can try Melamine (or Melamine cyanurate) + Phopsphate ester

Also possible: Magnesiumhydroxide (but this needs more filler content) => problems with mech. properties possible !!

Be aware: Solution 1 is regulary described in patents ...

What FR test do you have to pass (UL 94 ?) ?

Thank you for your reply.. But We had tired that condition..and not got a reasonable results. May be It would not match with Phosphate ester.. Have got any information about Phosphate ester grade? As you know, There are a lot of kind of Phosphage ester. Please.......!!!!!!!!!!!

An interesting material is: Resorcinol diphosphate FYROLFLEX RDP from SUPRESTA...Try Melamincyanurate / RDP =1:1...Already checked ?

Maybe ANTIBLASE V 490 or NCENDX P-30 (both produced from ALBEMARLE) are also of interest ...
