Borealis AG (U.S. office in Port Murray, N.J.) recently unveiled what is believed to the first HDPE for foamed communication cable that is free of azodicarbonamide (ADCA) blowing agent. New HE4873 is a fully formulated HDPE compound containing a blowing agent for physical foamed data cable insulation. It was developed in partnership with Scotland-based Brand-Rex Ltd, a leading developer of cabling solutions for network infrastructure and industrial applications. Borealis expects it to become the material of choice for next-generation, higher category communication cables.

            ADCA has been classified as a “substance of very high concern” due to its respiratory sensitizing properties by the European Chemical Agency (ECHA). Borealis’ HE4883 is said to be both ADCA-free and meets requirements for categories Cat 6, Cat 7 and Cat 8 physically foamed data cables. It boasts the same benefits as its predecessor HE4873—long the leading foamed data grade for Cat 7 data cables used in data centers. Other advantages include optimal cell structure, enhanced process stability and, higher line speeds (up to nearly 2000 m/min).
