A flame-retardant polybutylene terephthalate (PBT) resin grade from BASF is now being used in DC contactors in a rail application. These contactors must satisfy the stringent fire prevention requirements of the French Railway Standard NF F 16-101. The 25% glass fiber-reinforced thermoplastic Ultradur B4450 G5 is based on a special flame retardant system and, with its especially good values for smoke density and toxicity, satisfies the requirements for the I3F2 classification in this standard.
