Heat shrink: protecting cables from heat

A heat-shrink sleeve is a solution designed to protect cables and electrical components from high temperatures, temperature fluctuations and harsh industrial environments. It ensures the durability, safety and performance of electrical systems, even under extreme conditions.

Used in the energy, data centre, electric vehicle and rail sectors, it helps to reduce the risk of thermal degradation and extend the service life of installations.

At ADDEV Materials, we support manufacturers in selecting and integrating suitable thermal protection solutions, working in partnership with recognised suppliers.

Heat shrink tubing for industrial applications

In industrial environments, heat shrink tubing allows for:

  • to protect the electrical cables
  • to limit the effects of the heat
  • to secure the facilities
  • to improve system reliability

It is indispensable in high-thermal-stress environments.

Comparison:

  • heat shield
  • flame retardant sheeting
  • heat shrink tubing → snug protection
  • all-purpose protective sleeve

Each solution addresses a specific constraint.

What is a heat shrink tube?

A thermal sleeve is a technical sleeve designed to protect cables from:

  • excessive heat
  • temperature variations
  • prolonged thermal constraints

It is made from durable materials such as:

  • Silicone
  • fibreglass
  • high-temperature polymers

It represents a key solution for thermally constrained environments.

Thermal wrapping versus other solutions: What's the difference?

Heat shrink tubing vs fire-resistant sleeving

  • thermal → heat protection
  • flame retardant

Heat shrink tubing vs. heat shrink wrap

  • Thermal → Continuous protection
  • thermo → localised protection

Thermal ducting vs standard ducting

  • thermal → high-performance
  • standard → usage courant
