Why Choose the Partex HSMB12WHITE 2:1 Heat Shrink Tubing?

The Partex HSMB12WHITE is a compact 2:1 heat shrink tubing designed for electrical insulation, fine-wire protection and conductor sleeving in industrial, commercial and general electrical applications. Featuring a clean white finish, this tubing has a nominal supplied diameter of 1.2 mm and a nominal recovered diameter of 0.6 mm, making it particularly suitable for appropriately sized miniature electrical wires, fine conductors and compact wiring assemblies.

As part of the Partex heat shrink tubing range, the HSMB12WHITE provides a practical solution for insulating and protecting small-diameter electrical wiring. When suitable heat is applied, the tubing contracts around the underlying conductor or component, forming a close-fitting protective sleeve. Its 2:1 shrink ratio provides installation flexibility, while the white colour supports neat cable organisation and visual identification within appropriately designed wiring systems.

Supplied in a convenient 20 m pack, the Partex HSMB12WHITE is suitable for electrical panel builders, electronics technicians, cable harness manufacturers and maintenance engineers. Its 1.2/0.6 mm diameter specification makes it particularly useful for precision sleeving applications where compact dimensions, protective insulation and organised wiring are important.

Key Advantages

  • 2:1 heat shrink ratio: Allows the tubing to contract to approximately half its original nominal diameter when fully recovered.
  • 1.2 mm supplied diameter: Suitable for installation over appropriately sized miniature wires and fine electrical conductors.
  • 0.6 mm recovered diameter: Provides close-fitting protective sleeving around compatible small-diameter wiring.
  • White colour: Provides a clean, professional appearance and supports visual wire identification.
  • 20 m pack length: Offers a practical quantity for electrical assembly, production and maintenance applications.
  • Compact protective insulation: Supports the insulation and protection of suitable fine-wire assemblies.
  • Cut-to-length flexibility: Allows individual sleeves to be prepared for specific wiring requirements.
  • Neat wiring finish: Helps maintain organised conductor arrangements in electrical equipment and compact cable harnesses.

Key Features

  • Partex heat shrink tubing for electrical insulation and fine-wire protection.
  • HSMB12WHITE model designation for identification and ordering.
  • 2:1 nominal shrink ratio for close-fitting sleeving.
  • 1.2 mm nominal supplied diameter before shrinking.
  • 0.6 mm nominal recovered diameter after full recovery.
  • White tubing colour for a consistent appearance and visual wire identification.
  • 20 m supplied length for multiple installation and assembly tasks.
  • Heat-activated shrinking for protective sleeving of compatible miniature conductors.

Reliable Fine-Wire Insulation and Protective Sleeving

The Partex HSMB12WHITE provides a convenient method of applying protective heat shrink tubing to miniature electrical conductors and compact wiring assemblies. The tubing is positioned over the required section of wire before suitable heat is applied. As it contracts, the tubing conforms to the underlying conductor insulation or component, creating a close-fitting protective covering.

With a 1.2 mm supplied diameter and a 0.6 mm nominal recovered diameter, the HSMB12WHITE is particularly suited to applications involving fine electrical wires where larger heat shrink tubing would be unsuitable. Its 2:1 shrink ratio allows the tubing to accommodate compatible conductor dimensions while providing a neat and compact finished sleeve.

The white finish supports visual differentiation of wiring within appropriately designed cable identification systems. For effective installation, select tubing with a supplied diameter large enough to pass over the wire or component and a recovered diameter small enough to provide a secure fit. Apply heat evenly using suitable equipment, follow the manufacturer's installation instructions and confirm that the tubing meets the electrical and environmental requirements of the application.

Typical Applications

  • Fine electrical wire insulation and protective sleeving.
  • Miniature conductor protection in compact electrical assemblies.
  • Electronic equipment wiring and maintenance.
  • Control panel signal wiring and auxiliary circuits.
  • Small-diameter cable harness manufacturing.
  • Visual wire identification and cable organisation.
  • Instrumentation wiring and compatible low-voltage assemblies.
  • Electrical installation, servicing and repair work involving fine conductors.

Frequently Asked Questions

What is the Partex HSMB12WHITE used for?

The Partex HSMB12WHITE is designed for electrical insulation, fine-wire protection and protective sleeving on compatible miniature electrical conductors and compact wiring assemblies.

What does the 2:1 shrink ratio mean?

A 2:1 shrink ratio means the tubing can reduce to approximately half its original nominal diameter when fully recovered under suitable heating conditions.

What are the supplied and recovered diameters?

The HSMB12WHITE has a nominal supplied diameter of 1.2 mm and a nominal recovered diameter of 0.6 mm.

What colour is the HSMB12WHITE tubing?

The tubing is supplied in white, providing a clean appearance and supporting visual wire identification within appropriately designed electrical wiring systems.

How much heat shrink tubing is supplied in one pack?

Each pack contains 20 m of Partex white 2:1 heat shrink tubing, suitable for multiple fine-wire insulation and protective sleeving tasks.

Is the HSMB12WHITE suitable for very small electrical wires?

Yes. With a nominal supplied diameter of 1.2 mm and a nominal recovered diameter of 0.6 mm, the tubing is suitable for appropriately sized miniature electrical wires and fine conductors.

Can the HSMB12WHITE be used in electrical control panels?

Yes. The HSMB12WHITE can be used for compatible fine-wire sleeving, conductor insulation and wiring organisation within electrical control panels, provided the tubing meets the relevant installation requirements.

Can the HSMB12WHITE tubing be cut to different lengths?

Yes. The tubing can be cut to the required length before heating, allowing individual protective sleeves to be prepared for specific wires, conductors and electrical components.

How do I select the correct heat shrink tubing diameter?

Choose tubing with a supplied diameter large enough to pass over the wire or component before heating and a recovered diameter small enough to provide a close fit. For the HSMB12WHITE, the nominal supplied and recovered diameters are 1.2 mm and 0.6 mm, respectively.

Is the Partex HSMB12WHITE adhesive-lined?

An adhesive lining is not specified in the supplied HSMB12WHITE product information. Do not assume the tubing provides an adhesive seal or waterproof protection without confirmation from the manufacturer's technical documentation.

Can white heat shrink tubing be used for conductor identification?

Yes. White heat shrink tubing can help distinguish conductors within an appropriately designed wiring identification system. However, conductor identification must comply with applicable electrical installation requirements, and white sleeving must not replace mandatory protective conductor markings.
