PolyOne develops halogen-free flame retardant PBT compounds

PolyOne has recently introduced halogen-free alternatives to its Bergadur™ PBT product range. These products respond to an increasing market demand for non-halogen containing polymers due to growing environmental concerns against brominated flame-retardant polymer systems, which can release corrosive gases when burned, and also due to the introduction of the new WEEE directive.

Polyester compounds are widely used in the electrical appliance market because they possess: desirable dimension stability, tolerance for a high continuous service temperature, low thermal conductivity and good chemical resistance. However, with the introduction of new legislation and environmental concerns, customers are looking more and more for a halogen-free flame-retardant polyester polymer solution.

PolyOne has now developed a new range of PBT compounds made without the use of halogenated flame retardants, which meet these needs. The product range includes glass reinforced Bergadur grades like PB40 G10 HU (V-0 @ 0.8mm) and PB400 G30 U (UL-Approval V-0@ 0.9mm) which have a wide variety of applications in the electrical appliance industry.

The following table lists PolyOne’s “standard” grades Bergadur™ glass reinforced PBT compounds made without the use of halogenated flame-retardant systems (indicated by the suffix UF).
