Manufacturers, too, have a set of requirements that must be met: optimal space utilization, ease of assembly, sturdiness upon contact with objects, etc.
BASF have released Ultramid BWG6 CR (Crash Resistant), a stable glass-filled PA6 engineering resin with characteristics to minimise pedestrian impact. The lower bumper stiffener or LBS weighs just over two pounds, is three feet long and is installed behind the front bumper so as to diminish the risk of serious knee injury in the event of a collision with a pedestrian.Using Ultramid B3WG6 CR, real-world performance can be modeled so accurately as to minimise the need for prototype testing and significantly shorten the design cycle.
