New halogen-free flame retardant jacketing compounds for data center cables, control cables, energy cables, and other demanding applications exhibit a higher level of flame retardance than other high-performance HFFR materials without compromising physical or electrical properties, it was announced by Teknor Apex Company, which will introduce these products at the IWCS conference and exhibition (Booth 213).

Halguard® 58300 Series HFFR compounds with limiting oxygen indices in the 53-56% range enable cables to pass the stringent UL1685 vertical tray test (CSA FT4 / IEEE 1202) and achieve a UL94 rating of V-0 with test specimens as thin as 1/40 in. (0.635 mm). The compounds provide this outstanding flame performance while exhibiting the same physical and electrical properties of other high-performance HFFR materials (see accompanying table). Available grades are in the 48-52 Shore D hardness range.

Teknor Apex recommends Halguard 58300 Series compounds for data centers and other applications requiring exceptional flame retardance. One example is the extensive “server farms” operated by Internet companies.

“We believe that Halguard 58300 Series compounds are the most flame-retardant HFFR products on the market,” said Michael Roberts, industry manager for the Vinyl Division of Teknor Apex. “While modifying HFFR compounds to enhance their flame performance often involves sacrificing other properties, Teknor Apex has developed formulating and compounding innovations that avoid this tradeoff.”
