Ampacet Introduces Low Halogen and Halogen-Free Flame Retardant Masterbatches

Halolite 527 and Halofree 533 flame retardant masterbatches have been developed to comply with international standards IEC 61249-2-21 and EN 50642

Ampacet, a global masterbatch manufacturer, has introduced Halolite 527 and Halofree 533, low-halogen and halogen-free flame retardant masterbatches, to comply with international standards IEC 61249-2-21 and EN 50642 regulating maximum halogen and antimony content.

Good fire resistance is required for electrical equipment used in the Building and Construction sector to help ensure safety in case of fire. The previous generation of flame retardant solutions, based on halogens (bromine and chlorine) and antimony provide excellent flame resistance. However, when burning, these substances generate toxic and corrosive gases and present an environmental risk and a hazard for humans when inhaled.

For new installations in the Building and Construction sector, use of low or halogen-free flame retardant solutions is required to comply with EN 50642 and IEC 61249-2-21 standards.

Designed for use in polypropylene electrical equipment as well as other PP injected or extruded plastics used in Building and Construction, Ampacet Halolite 527, which contains low levels of halogen, and halogen-free Halofree 533 have achieved a UL94 V2 classification and high Glow Wire Flammability Index (GWFI) in compliance with EN 50642 and IEC 61249-2-21 standards.

Halolite 527 and Halofree 533 are available in a natural color and can also be colored by adding separate color masterbatches; pre-colored versions can be developed upon request.
