A series of color concentrates for wire and cable and other electronic applications required to be halogen-free (HF) has been certified by UL as conforming to its standard for HF materials, it was announced today by the Color Division of Teknor Apex Company.

The UL certification applies to 14 concentrates supplied by Teknor Color in pellet form, using ethylene-vinyl acetate (EVA) and polyethylene (PE) polymers as carrier resins.  These new concentrates can be used with EVA or polyolefin-based halogen-free flame retardant (HFFR) compounds currently available.

“Compliance with HF requirements has become increasingly important in North America, particularly for electronics, cables and cords used in confined spaces in office, building and construction, automotive, public transit, marine, and military installations,” said Edwin Tam, manager of marketing and business development.  “These applications require HF materials, and that includes the concentrates used to color the HFFR compounds.  We worked very closely with our wire and cable customers to develop these new concentrates specific for this market and obtaining the UL approvals.”
