A patent published today shows that Apple is investigating new halogen free, flame-retardant materials for use in its devices.
According to Apple, only about 12% of plastics currently contain flame retardants. An increased use of such materials would improve the safety of electrical wiring and electronic devices, and help reduce the number of fires caused by electronic devices as a result.
Halogenated flame retardants have been found to be effective in many plastics, but these are increasingly regulated as a result of environmental concerns. Since sustainability is a big topic for Apple, the company therefore wanted to discover a material that would possess similar fire-retardant qualities, while also not being damaging to the environment.
Tuesday’s patent describes a material with these qualities, that also produces only negligible amounts of toxic substances while burning. As per Apple, the material could be used in devices including the iMac, MacBook Pro, iPhone, and iPad.
