Heat Reflective Sleeving Manufacturer in India
If you need to keep the heat off, however, mere insulation won’t do; what you require is something which actively shields the component from the heat, rather than absorbs it. Heat Reflective Sleeving performs precisely this function, being a coated braided fiberglass sleeve specially designed to reflect most of the radiant heat off before it even gets to your wires, cables, hoses or hot running components.
As a leading heat reflective sleeving supplier in India, we at Harnawa Inc. provide high performance reflective sleeving for automotive, industrial and mechanical manufacturers all over India with international certifications and nationwide delivery from our Mumbai manufacturing facility, cementing our standing as a reputed Electrical Insulation Materials Manufacturer in India.
Reflection vs. Insulation — Why the Distinction Matters
While many other sleeves are based on the principle of insulation, whereby heat transfer slows down through an insulating layer, Heat Reflective Sleeving uses a different approach by reflecting radiant heat back to its source using an aluminum-coated outer shell. The difference is crucial because in cases where the heat level is high, such as in engine bays, exhaust systems, or furnace areas, it is radiant heat that poses the danger, and not high temperatures around the area. While other sleeves get saturated with heat at some point, this kind does not.
Built to Take the Heat — Literally
Every layer of this sleeving is chosen for one job: standing between your components and intense radiant heat.
- Braided Fiberglass Core – Supplies the framework and flexibility along with natural heat-resistance properties making this material suitable for direct installation over assemblies which operate at high temperatures
- Reflective Aluminum Coating – Active heat rejection material that is designed to reject most of the radiant heat coming its way
- Smooth Inner Layer – Can be easily slipped over existing hoses, cables and wiring without any tools
- Can Handle up to 250°C Heat Continuously – Remains functional even at high temperatures where other types of sleeving may not remain effective
- Inherently Flame Resistant – Since the material is made of fiberglass, it has natural flame-retardant properties

One Product, One Job — And It Does It Well
While other types of insulation sleeves have both the electrical and thermal aspects of their construction mixed together, Heat Reflective Sleeving is designed only for one application – where radiant heat is the enemy, and your equipment must withstand it. This type of sleeve is not certified to withstand electrical voltage; therefore, in case you need both functions, you should use another accessory.
Completing Your Thermal & Electrical Protection System
Heat Reflective Sleeving provides radiant heat protection – but in the majority of applications, this is not enough protection to work alone. In view of this, in combination with Heat Reflective Sleeving, you can use:
Sourcing your complete thermal and electrical protection system from a single certified supplier means every component is built to work together — not just sit next to each other.

Frequently Asked Questions
1.Where is Heat Reflective Sleeve used for?
For insulating cables and hoses from heat radiation sources, such as exhaust systems, engines, furnaces, and other heat generating equipment.
2.What makes Heat Reflective Sleeve different from ordinary insulation sleeves?
In contrast to ordinary insulation sleeves that prevent thermal conduction by means of heat barrier, Heat Reflective Sleeve with its heat reflective aluminum layer reflects heat radiation from the protected components.
3.What temperature range is this sleeve suitable for?
This sleeve can function continuously in the range of -30°C to +250°C.
4.Does this heat reflective sleeve provide electric insulation?
No, it does not. This product offers thermal/radiant heat insulation only, and is not designed to be electrically insulated. If electric insulation is needed, use Heat Reflective Sleeve in combination with electrically insulated sleeve, e.g. PU or Silicone Sleeve.
5.What industries use this kind of sleeving?
It is widely used in automotive and mechanical industries.
