Polymers pass tougher 'glow-wire' tests
The revised IEC 60335-1 standard lays down tighter requirements for the
'glow-wire' test of plastic materials used in the construction of
electrical components, particularly for domestic electrical equipment.
The standard calls for higher temperatures and shorter permitted
after-burn times. DuPont says many of its flame retardant grades now meet
these new requirements, including its Crastin PBT, Rynite PET, and Zytel
series nylons. In addition, its Zenite LCPs and some Zytel nylons meet
demand for flame retardancy without halogen and red phosphorus content.
