Apple restricts nearly all uses of brominated and chlorinated compounds, at the elemental level, from its products. Customers can now purchase products like the iPod shuffle, nano, and touch, and the iPhone that are free of brominated flame retardants (BFR s) and polyvinyl chloride (PVC). Apple’s iMac and Macbook products are free of all BFR s and PVC with the exception of PVC use in external wires. Apple had to work with suppliers to change the composition of hundreds of parts, including printed circuit boards (PCBs), connectors, fan impellers, cable insulators, adhesives, films, inks, dyes, flexible printed circuits, and enclosures. To implement its restrictions, Apple required its suppliers to establish strict compliance management programs.
