Sumitube® Heat-shrinkable tubing
Heat-shrinkable tubing meets all major commercial and military specifications including AMS-DTL-23053, UL and CSA. Materials available include polyolefins, flouroplastics, and elastomers. Single and dual-wall constructions are available. Sumitomo Electric also offers custom design capabilities and specialty tubing for applications which require them. Examples include low-smoke materials, medical grades, conductive tubing and many more.
- SUMITUBE®, offered by Sumitomo Electric Fine Polymer, is a complete line of high performance heat-shrinkable tubing developed from a variety of materials. These products are available in a wide range of sizes, colors and types suitable for various applications.
- ALL SUMITUBE® products are made of irradiated cross-linked polymers (polyolefin, PVC, PVDF, and other types) and all have excellent dimensional stability and superior heat resistance characteristics. Upon the controlled application of heat, the diameter of SUMITUBE® products can be reduced to a pre-determined size. SUMITUBE® products provide an excellent conformal & protective covering over substrate components when the shape or outer diameter of the object to be covered is larger than the recovered inside diameter of the SUMITUBE® product. They are normally supplied expanded to a 2:1 ratio.
- SUMITUBE® products comply with many applicable industry standards and military specifications, and are designed for use in military and commercial electronics, telecommunications, aerospace, automotive, and many other areas of industry.
- Cutting and/or marking services are also available upon request. Please contact us for further information.
- Sumitomo Electric Fine Polymer has had a continuing commitment to radiation cross-linked polymer development and superior quality products since 1959. It is their intent to continue to meet these obligations in the future with a continued dedication to quality, service and problem solving solutions.
