Cable makers focus on CPR

SACO AEI Polymers has launched two novel low smoke halogen free compound families for the cable industry.

Allan Marconi, Marketing Manager at compound producer SACO AEI Polymers, also says the new regulation has presented the industry with some headaches. “The CPR has provided significant challenges for cable makers in meeting the appropriate level of the requirement as dictated by the installed environment,” he says. The company has just announced what it describes as some breakthrough low smoke halogen-free compounds for wire and cable that use proprietary patented technologies. “We have two new technologies that can give the cable maker a solid opportunity to reach B2 on certain cable constructions,” Marconi says. THERMODAN® HF TP343 thermoplastic low smoke zero halogen jacket compound has shown very good performance in meeting B2 and C levels in both fibre optic and copper media cables. THERMODAN® Global Product Manager Dean Jenne says it has been developed in response to the need for a more cost-effective solution for this market. “In copper media cables, the 22-mil [0.56-mm] thin wall jacket reduces the cable diameter by up to 7%, saving space, up to 30% reduction in weight and significant volume cost savings over conventional LSHF jacket solutions,” he says. PEXIDAN® HF S/C-UV, a moisture-curing lowsmoke zero-halogen XLPE thermoset jacket compound, also has the capability to fit into the higher-level performance classifications of CPR. Jenne says it meets the need for a more cost-effective solution for the fast-growing low smoke zero halogen application sector in North America. However, Jenne explains that the results any wire and cable maker will get in classes of CPR are also dependent on factors beyond the actual compound itself. “No compound manufacturer can guarantee the cable maker to meet a specific level of CPR, only that their experience is that the compound has the capability to meet CPR. B2 and C are the classifications most commonly required,” he says.
