Advances in TPE styrenic block copolymer compounding for UL flame retardant cable applications

摘要

Teknor Apex Company has undertaken research and development efforts in the TPE styrenic block copolymer compounding technologies to develop new RoHS-compliant enhanced flame retardant (FR) compounds. This paper will detail the performance of new compounds using different UL vertical burn test methods. EL-1392B (Shore A 86), EL-1934E (Shore A 82), and EL-1934F (Shore A 73) pass UL 94 V-0 rating at a thickness of 0.06". These compounds also pass UL 1581 VW-1 and method 1061 for cable flammability tests for insulation and jacketing. They are ideal for flexible cords, coil cords, robotics cables, power tools, high-flex cables, low temperature applications, and connector parts and components requiring a V-0 flame rating.
