Sumitomo

At Sumitomo Electric Interconnect Products (SEIP), we’ve been producing superior quality heat shrink tubing products since 1996. Our products, designed to perform in the harshest environments and the most extreme conditions, are qualified, certified, and approved to national and international standards. Thanks to our global reach, many high-profile customers rely on us to support their supply chain needs.

Our Sumitube heat-shrinkable tubing utilizes the shape-memory effect of plastics, enhanced by electron beam irradiation.

Our high-performance cable identification ranges, SumiMark and Sumitag, developed for the cable assembly identification industry, include marking systems, heat shrink sleeves, and non-shrink panel labels and cable labels.
