Applications: TY-109 provides outstanding thermal stability and electrical performance. It is particularly suitable for engineering plastic applications such as polyesters(PET,PBT,PCT)and polyamides(nylons).It has outstanding thermal stability , it is an ideal choice for high temperature applications such as engineering plastics . Due to its stability , it can often be used where other flame retardants fail to survive . Due to its polymeric structure , it is non-blooming in all applications . Excellent electrical properties provide yet another reason to choose this flame retardant for demanding engineering plastic applications.
