Shanghai Metal Corporation is one of the leading and reliable manufacturers and exporters of Shrink tubes in China. We provide the high quality matched products and excellent services for various industries.

The printable heat shrink tube is specially designed for high-performance wire and cable signs. It is made of radiation cross-linked high-quality temperature-resistant 135℃ soft and high flame-retardant polyolefin material. Polyolefin heat-shrinkable identification sleeves are used for the permanent identification and protection of wires, cables, terminals, and wiring harnesses. They can be printed with wire numbers, equipment codes, serial numbers, barcodes, or warning information and then secured to the cable by heat shrinking. They are widely used in electrical cabinets, automotive wiring, telecommunications, railways, aerospace, marine, and industrial equipment, providing clear identification as well as insulation and protection against abrasion.

If you want to know more about our Polyolefin heat shrinkable identification sleeve, please feel free to contact us, we will reply you within 24 hours.

1.Waterproof: IP65 – Dust-tight and resistant to water jets.

2.Operating Temperature: −55°C to 135°C – Performs reliably across a wide temperature range.

3.Initial Shrinkage Temperature: 70°C – Begins shrinking at approximately 70°C

4.Minimum Full-Shrink Temperature: 110°C – Fully contracts at 110°C or above.

5.Environmental Standard: RoHS – Complies with RoHS environmental requirements.

6.Standard Colors: White and Yellow – Other colors are available upon request.

1.Simple and Safe : Cover the exposed part that requires maintenance with these tube sand use a heat gun to shrink them quickly and evenly to form a neat and lasting tight joint.

2.ECO-Friendly: Our heat shrink tubes are RoHS Compliant which ensures its safe and reliable. Does not contain heavy metal and other environmentally hazardous substances.

3.High Flame Retardancy: The sleeve is designed to resist ignition, limit flame propagation, and self-extinguish quickly after the flame source is removed. This helps reduce the risk of fire spreading along cables and wiring harnesses.

4.The polyolefin sleeve does not rust or corrode and helps protect wires, cable markers, and underlying components from moisture, salt spray, oils, and certain chemicals.

1.Wire/Cable Identification: The sleeve can be printed with wire numbers, circuit codes, equipment references, bar codes, or warning information, providing clear and durable identification throughout installation, inspection, and maintenance.

2.Insulation Protection: After heat shrinking, the sleeve fits securely around the wire or cable and provides an additional insulating layer.

3.Cable Identification Management: Color coding and printed information allow cables and wiring harnesses to be systematically classified and tracked.

4.End-Cap Protection: The sleeve can be applied over cable ends, terminals, and connection points to help prevent abrasion, dust contamination, and handling damage.
