Original Press Release:
Glass-Filled Nylon with Non-Halogen FR System Has Lower Density and Higher Tracking Index Than Halogenated Compounds
With More than Double the Tracking Index, New Chemlon® 225 GVNH Provides Superior Electrical Performance Required for Device Housings, Charger Covers, Other UL V0 Uses
PAWTUCKET, RI, U.S.A., March 27, 2009: A new 25% glass fiber-reinforced nylon 6 compound provides injection molders with an alternative to halogenated flame retardant (FR) formulations while meeting stringent requirements for flame retardance, it was announced today by Chem Polymer, a unit of Teknor Apex Company. Chem Polymer will introduce the product at NPE2009 (Booth 92020).
Chemlon® 225 GVNH has a UL 94 flammability listing of V0 at thicknesses down to 0.032 in. (0.8 mm). Its comparative tracking index of 600 V is more than double that of a comparable compound with a halogenated (typically brominated) FR formulation, providing superior electrical performance in automotive, residential, and appliance applications such as housings with snap-fit assembly, circuit breakers, charger covers, and safety switches. The new compound is also 14% less dense, yielding lighter parts.
Although the Chemlon product is currently UL-recognized only in black formulations, its FR formulation is expected to provide a broader range of colorability than brominated FR systems and non-halogenated ones based on red phosphorus, according to Richard Barnes, technical manager. Typically these permit only dark colors.
"Because non-halogenated FR systems have been more difficult to incorporate into glass-filled compounds than brominated ones, relatively few non-halogenated nylons have been available in North America," said Barnes. "Our new Chemlon compound will provide a higher-performance alternative for North American molders seeking to serve the world market for components requiring flame retardancy."
Chemlon 225 GVNH is already in commercial use for the housing of an air filter used in a vehicle engine compartment.
