Heat Shrink Identification & Marking Products

English version - Heat shrink tube - Yozonetech company profile

Product Overview

Yozonetech Identification Products for Wire & Cable are designed for permanent, durable and highly legible identification of wires, cables, harnesses and bundled conductors. The source catalogue presents a dedicated range of heat-shrinkable marking sleeves, identification tags, ladder-type thermal-transfer markers, ribbon and printing software. The product families are intended to cover conventional commercial environments as well as military, aerospace, marine, rail, mass-transit and other applications where identification must remain readable after exposure to abrasion, cleaning solvents, industrial fluids or demanding environmental conditions.

The main sleeve families are AMS, RSFR, PSFR, HMS and HNF. Although their construction and operating limits differ, they share a common purpose: creating a durable identification layer directly around a wire, cable or harness. PUR identification tags provide a non-shrink tag format for cable and bundle marking, while the RSFR/AMS/HMS/HNF ladder-type tags are intended for larger cable and bundle identification. WO-80500BK provides the recommended black resin thermal-transfer ribbon, and WOLABEL-1/3 provides software for label design, data management and repeat printing.

Product Family at a Glance

AMS — Military Identification Sleeves

Permanent wire and cable marking for demanding applications

AMS marker sleeves are designed for permanent wire and cable marking. The source describes them as durable and flame-retardant heat-shrinkable polyolefin sleeves radiation cross-linked by a high-energy electron beam. They are suitable for military industry, aerospace and defense, and marine applications.

RSFR — Heat Shrinkable Identification Sleeves

RSFR is a flattened heat-shrinkable tubing for wire and cable harness identification where limited fire-hazard characteristics are required. The source states that, when printed with recommended printers and ink ribbons, the marking remains legible and durable after abrasion, aggressive cleaning solvents and industrial fluids.

RSFR Physical Performance

PSFR — High-Temperature Heat Shrinkable Identification Sleeves

PSFR is the high-temperature identification sleeve in the source catalogue. It is a flattened heat-shrinkable sleeve for wire and cable identification where elevated temperature capability and resistance to fuels, lubricants and cleaning solvents are important. The source lists aerospace, defense and mass-transit industries as the application range.

PSFR Dimensions

HMS — Diesel Resistant Identification Sleeves

HMS marker sleeves are designed for identifying wires and cables exposed to organic fluids, especially diesel oils, for prolonged periods and at elevated temperatures. The source positions HMS for military, aerospace and defense, and marine applications.

HNF — Halogen-Free Low-Smoke Low-Hazard Identification Sleeves

HNF is designed for wire and cable harness identification where limited fire-hazard characteristics are needed. The source emphasizes its zero-halogen material, low smoke and low toxic-fume characteristics for enclosed or transport environments.

PUR — Identification Tags

PUR cable markers are made from thermoplastic polyurethane. The source describes the material as halogen-free, flame-retardant, hydrolysis-resistant and microorganism-resistant, with raw material fulfilling UL94-V0. The markers are supplied on rolls for thermal-transfer printing and can be removed from the carrier and applied to cables and wire bundles using cable dies.

RSFR / AMS / HMS / HNF — Ladder-Type Identification Tags

The ladder-type identification tag is a thermal-transfer marker made from environment-friendly polyolefin material cross-linked by high-energy electron bombardment. The source describes these tags for high-reliability identification of large-diameter cables and wire bundles, including high-speed rail, subways, MU trains, nuclear power stations, aircraft and space-shuttle environments. Markers can be removed from the carrier and applied to cables and bundles using cable dies.

WO-80500BK — Thermal-Transfer Ribbon

WO-80500BK (N85) is the ultra-high-durability black resin thermal-transfer ribbon specified in the source for WOER identification sleeves and cable marker tags. Using a compatible printer and ribbon is important when the application requires durable marking performance.

WOLABEL-1/3 — Wire Marker & Label Printing Software

WOLABEL is industrial software designed for wire-marker and label printing. The source describes functions for label design, editing, graphics, repeat printing, data management, Excel import/export and multi-line or array printing. The interface is available in English and Chinese versions.

How to Select the Right Identification Product

• For military, aerospace, defense or marine identification where the source specifically lists AMS-DTL-23053/5 compliance, consider AMS.
• For general commercial and industrial wire or harness marking, RSFR provides a dedicated heat-shrink identification format with 2:1 and 3:1 options.
• For elevated-temperature applications, PSFR is the high-temperature family, with a source-listed operating range of -55 to +225°C.
• Where prolonged exposure to organic fluids, especially diesel oils, is expected, HMS is the dedicated diesel-resistant identification sleeve.
• For rail, mass transit, marine and enclosed environments where halogen-free, low-smoke and low-hazard characteristics are important, HNF is the corresponding family.
• For a non-shrink identification format applied with cable dies, PUR tags provide a separate thermoplastic polyurethane solution.
• For larger-diameter cables and wire bundles requiring ladder-style thermal-transfer markers, use the RSFR/AMS/HMS/HNF ladder-type range.
• For durable printing, match the sleeve/tag family with the recommended ribbon and compatible printer listed in the source catalogue.

Printing & Ordering Considerations

Identification performance depends not only on the sleeve or tag itself but also on the selected dimensions, print format, printer, ribbon and installation method. The source provides a part-numbering structure that encodes product family, shrink ratio or tag geometry, size, sleeve/tag length, packing quantity, color and printing configuration. For AMS, RSFR, HMS and HNF sleeve products, the source also distinguishes continuous and ladder formats and gives package quantities by ordering size.

For project procurement, the buyer should provide the cable or wire outside diameter, required recovered diameter, identification text, printing side, required color, approximate annual quantity, operating temperature and the main environmental exposures. For diesel, industrial fluids, high temperature, rail/mass transit or military/aerospace applications, the service environment should be stated before the product family is selected.

Installation & Identification Workflow

• Select the product family according to temperature, chemical/fluid exposure, fire behavior and applicable standards.
• Choose the supplied ID so that the sleeve can be positioned over the wire/cable before recovery, while the recovered ID and wall thickness meet the application requirement.
• Select the required shrink ratio: AMS and RSFR are available in 2:1 and 3:1 configurations; PSFR and HNF are 2:1; HMS is 3:1.
• Choose continuous or ladder format when the selected product family provides both options.
• Prepare the marking using the recommended thermal-transfer ribbon and compatible printer.
• Apply the sleeve or tag to the cable or bundle using the appropriate installation method and confirm that the marking remains legible after installation.
• For large cable bundles, consider ladder-type markers where the larger marker dimensions and thermal-transfer format are more suitable.
