Here, formulations with aluminium diethyl phosphinate meet the glow wire ignition test ( GWIT ) at 775 �C and the glow wire flammability test ( GWFI ) at 960 �C . Another important criterion in E & E applications is the Comparative Tracking Index ( CTI ), which determines the risk of electrical tracking of insulating material that is exposed to contaminating environments and surface conditions.

In glass fibre reinforced ( GF ) polyamide 6 ( Nylon 6 ) and 66 ( Nylon 66 ) formulations as well as in polyesters like polybutylene terephthalate ( PBT ) and PET, aluminium diethyl phosphinate shows excellent performance in the UL 94 flammability tests ( UL 94 V0 specification is met down to 0.4 mm ), as well as in the glow wire tests required for appliances.
