Special shrinkable tubingTalented specialists for special tasks.

Flexible and simultaneously sealing? Thin-walled, yet robust? Quick to install and extremely durable in use?

Our special heat shrinkable tubes are ideally suited for special requirements. Many models are compliant with international standards and offer high-performance alternative options for a variety of different applications and specifications.

Special shrinkable tubing by Raychem

Our tubes by the technology leader, Raychem are precisely manufactured and made of particularly high-quality materials: polyolefins, fluoropolymers, and elastomers, as well as special mixed forms thereof. By using a special crosslinking process, the materials are thermally and chemically stabilised. Furthermore, they are heat-shrinkable and infusible. These features allow for easy assembly and adjustment of the tubes to each pipe diameter and each object shape. Insulation, protection and labelling are also ensured in difficult applications through:

  • Special measurements (diameter, wall thickness, length)
  • Cutting and printing according to customer's drawing
  • Extraordinary materials
  • Numerous colour variants
  • Application-adapted adhesive properties
  • Diversity in shape, colour and function
  • Moisture, mould and weather-resistant for outdoor use
  • Insulation and strain relief for delicate measuring wire and fibre optic cable
  • Protection and insulation for shielding connections/shielded splice
  • Noise reduction for piping
  • Mechanical protection of media-carrying tubing
  • Thermal insulation of substrates, pipes, tubing and cables
  • Battery terminal marking and sealing

Suitable for special sizes, particular specifications and tolerances

In many cases our shrinkable tubing captivates people by its sturdiness, durability and universal application possibilities. It offers reliable insulation, mechanical protection, strain relief and a clean design. Choose between highly flexible and semi-rigid designs, select the optimal product for your application from a wide range of different colours, physical properties and sizes. Flame-resistant, halogen-free, adhesive-coated products, as well as products corresponding to particular specifications, are all available to our customers in different presentations - as spool products, in lengths pre-determined by you and optional printed or unprinted cuttings.

Significant benefits at a glance:

  • Shrinkage rate from 2:1 to 4:1
  • Excellent resistance to thermal, chemical and mechanical influences
  • Optionally available in high flame-retardant version
  • Many colours available
  • Halogen free option
  • Resistant to cold flow
  • Approvals in accordance to UL, CSA and other international standards
  • Specifications according to AMS-DTL-23053, MIL-PRF-46846 and EN-45545
  • Special variants available

  • Shielded splice protection
  • Noise reduction for piping
  • Mechanical protection of the tubing
  • Thermal insulation of substrates, pipes, tubing and cables
  • Battery terminal marking and sealing
  • Moisture, mould and weather-resistant for outdoor use
  • Insulation and strain relief for delicate measuring wire and fibre optic cable

Selection of Raychem special shrinkable tubing

ATUM

Protects and seals a variety of electrical applications from the ambient environment, especially suitable for transitions of connector housings for cable branches and connector-to-cable transitions. The high expansion ratio enables the repair of most damaged cable sheaths without having to remove the connectors.

BRST

Provides excellent electrical insulation and is particularly suitable for noise-damping measures and for mechanical protection.

BSTS/BSTS-FR

The BSTS heat shrinkable tube consists of a robust polymer, resistant to moisture, mould and weathering. It also offers outstanding electrical properties. This shrinkable tube is suitable for applications where insulation, abrasion resistance and strain relief are crucial. Together with a sealing strip (S-1305 for flame retardant or S-1278 for non-flame retardant versions) it provides a watertight system for non-pressurised applications.

CGAT

CGAT is a flexible heat-shrinkable polyolefin tubing with an inner fusible adhesive coating for universal application. It is suitable for the protection of electrical components from environmental influences and for isolating conductors. Typical applications include the sealing of electrical components against environmental influences as well as the strengthening of cables and wires for harsh application environments.

DR-25

This high-class elastomer shrinkable tubing is flexible, flame retardant, as well as particularly resistant to chemicals and abrasion. It forms the base component of the 25-cabling system, which is especially designed for optimal resistance to hot liquids and persistent heat.

ES/PD-caps

These insulating caps are quick and easy to install and provide excellent strain relief, protection against abrasion, vibration damping and flexing through a mechanically robust outer casing. The PD caps offer a spill-resistant cover. ES caps have a shrink ratio of 4:1.

HFT5000

Its highly flexible fabric makes HFT5000 the ideal abrasion protection for rubber tubing, plastic pipes and wiring harnesses. It provides a shrink ratio of 2:1, is halogen free and can be used across a wide temperature range.

Sealing systems RayBlock 85 and RayBlock 105

The heat-shrinking sealing systems RBK-85 and RBK-105 are designed for permanent longitudinal sealing of cable bundles. The typical application range of RBK includes performing wiring harnesses through spraying walls, as well as the rear seal of connectors. RayBlock (RBK) supports noise-damping and compact constructions and also seals extensive cable bundles reliably.

RNF-150

With a shrink ratio of 2:1, this flexible, high-performance fluoropolymer tubing is designed for the wrapping and bundling of wires in harnesses for light duty and is particularly suitable for applications requiring abrasion resistance and flexibility in a compact design. Extremely flame retardant, resistant to many chemicals, with excellent physical and electrical properties.

RT-375

This particularly flame-resistant, clear and flexible fluoropolymer tube with good mechanical and electrical properties is used to protect extremely stressed wire and cable markers and maintains the legibility of the label. It provides a shrink ratio of 2:1 and extraordinary transparency, and exhibits chemical resistance and durability at high temperatures.

RW-175

This chemically resistant polyvinylidene fluoride high-temperature tube is a robust, semi-rigid, extremely thin-walled insulation product and is suitable for applications requiring reliable operation at high temperatures, superior abrasion and impact resistance and high chemical and solvent properties. It provides a shrink ratio of 2:1.
