Sumitomo Electric Develops Highly Markable, Halogen-Free, and Heat-Shrinkable Tube

Heat-shrinkable tubes

Railway vehicles and aircraft need to employ heat-shrinkable tubes for harness identification, and thus require highly markable, halogen-free products that create the least hazardous smoke and acid gas in case of fire. Sumitomo Electric has recently developed a highly markable, halogen-free, and heat-shrinkable tube, Sumitube™ NH34, which particularly fits this application.

The product complies with the industry’s tough standards, BS*16853 regarding flame resistance and smoke evolution and SAE*2-AS5942 regarding marking. Conventional halogen-free products are not so good at marking, due to the volume of flame-retardant composition. We have fundamentally reviewed the compositions and developed a highly markable tube, which also satisfies necessary requirements of general insulating tubes. Sumitomo Electric is committed to developing products that serve customers’ needs.
