"NOVADURAN SEF series" Halogen-Free flame retardant PBT

November 10, 2009

"NOVADURAN SEF series" is a brand-new halogen-free flame retardant PBT developed with the original flame retardant technology. SEF series is classified UL94 V-0 and good electric insulation characteristics.

NOVADURAN SEF series enable to markedly improve the safety of the electric and elctronic equipmets.

Low mold deposit and low volatile types are also available.

Features

  1. Bromin free flame retardant
  2. High tracking resistant : CTI(≧600V : PLC0)
  3. Low volatile matter
