GREAT LAKES LAUNCHES HALOGEN-FREE FLAME RETARDANT FOR POLYPROPYLENE
22 October 2004 - Great Lakes Chemical Corporation

Great Lakes Chemical Corporation has launched Reogard 2000 intumescent flame retardant, a cost efficient, halogen-free product for polypropylene and other polymers. Reogard 2000 flame retardant is ideally suited to applications that demand a highly efficient, halogen-free flame retardant such as extruded building parts and plastic components for electrical applications subject to the UL94-VO flammability standard. It is free from ‘milky’ water baths during extrusion and the production of ammonia odour, which can be a concern with other competitive intumescent technologies. In addition, the UL94-VO standard is achieved with Reogard 2000 at significantly lower flame retardant load levels in the polypropylene homopolymer resin than the load levels normally required for competitive systems.
Reogard 2000 also offers superior physical properties such as higher impact strength and a higher heat distortion temperature (HDT) than other intumescent flame retardants. The higher HDT means that the polymer can be removed from the mould earlier, thereby reducing the molding cycle.
Delamination, when the surface layers start to separate from the polymer during moulding, does not occur even at temperatures up to 210C. In addition, because Reogard 2000 is partially melt blendable, it can be compounded at lower temperatures offering potential energy savings.
