New Flame-Retardant Grade for Electronics and Electrical Engineering Sectors

Flip the switch safely – with engineering plastics from BASF, is a new PR title from BASF company having focus on:  A) Expanded range for circuit breakers with new; B) Gglobally available Ultramid® grade; C) Particularly suitable for household applications

BASF is now expanding its PA (PA: polyamide) range to include a new flame-retardant grade for use in the electronics and electrical engineering sectors. Ultramid® B3U31G4 impresses in the glow-wire test, is noted for its good mechanics and good processing properties and is particularly suitable for manufacturing circuit breakers for domestic use. BASF is rounding off the product range and thus offering plastics for both market segments: highly specialized circuit breakers for industrial and household applications.

Circuit breakers safeguard circuits and, in an emergency, cut off the power supply reliably within milliseconds. This occurs both in the event of brief power surges and in the event of an excessive continuous load. The plastics from which these circuit breakers are manufactured must therefore meet high requirements in terms of their mechanical properties and fire behavior (glow-wire test at 960°C). Ultramid B3U31G4 passes this crucial glow-wire test with a wall thickness of 1 millimeter.

Likewise, the circuit breakers need to be reusable after they have been triggered, for example after a short circuit caused by incorrect operation, or an assembly or commissioning fault. This means the housing of the circuit breaker must withstand the energy which is explosively released. Only then can the switch simply be flipped back after such triggering and the protective function be restored immediately. Thanks to the combination of outstanding mechanical properties with good flowability, the new Ultramid grade is particularly suitable for this application.

Ultramid B3U31G4 is available right now in white and in several shades of gray. Further Ultramid grades for this specific application are already being developed – their global market launch is scheduled for the first half of 2018.
