The sulfone family (PSU, PESU, PPSU) and PEEK are inherently flame retardant, with grades meeting V-0 without added flame retardants. BASF Ultrason® P 3010 is V-0 at both 1.5 mm and 3 mm, and Joyrun PEEK K10G is also rated V-0.

Material requirements — Electrical & Electronics
6 requirements01Flame rating (UL94)V-0 must be met at thin wall sections. Sulfones and PEEK are inherently flame retardant.
02Dielectric strength & propertiesElectric strength, permittivity and dissipation factor must suit the circuit requirements.
03Tracking resistance (CTI)Must resist insulation failure from tracking in contaminated or humid environments.
04Reflow & high-temperature resistanceNo deformation or property loss during assembly and in service.
05Dimensional stabilityFine-pitch connectors need low shrinkage and thermal expansion — addressed with GF reinforcement.
06Identification colour without losing ratingsFlame rating and properties must survive coloring.
