High Temperature Heast Reflective Aluminized Aramid Kevlar Heat Barrier

Product Description

High Temperature Heat Reflective Aluminized Aramid Kevlar Heat Barrier is a professional grade thermal shielding fabric designed to reduce radiant heat transfer and protect people, equipment, and surrounding structures in high heat environments. It combines a strong aramid Kevlar base cloth with a heat reflective aluminized surface to deliver reliable performance where flame risk, hot air exposure, and radiant heat loads are present.

This material is widely used for industrial heat shields, insulation jackets, welding curtains, protective covers, heat deflectors, and thermal barrier panels in automotive, marine, power generation, metal processing, and heavy manufacturing applications.

Material Construction and Working Principle

This heat barrier uses a Kevlar aramid textile foundation for strength and stability, combined with an aluminized reflective surface that redirects radiant heat away from the protected side. In practical use, the reflective face is oriented toward the heat source to maximize reflection. The aramid layer contributes structural support for long term use in demanding environments, making the material suitable for both fixed barriers and removable insulation systems.

 

Processing Guidelines

For cutting and sewing, use compatible high temperature threads and proper edge finishing to reduce fraying. For insulation jackets, pairing with suitable insulation cores can improve total thermal protection. For curtain and screen applications, stable mounting helps maintain consistent barrier coverage.

 

Frequently Asked Questions

Q1. What is this aluminized aramid heat barrier mainly used for

It is mainly used as a heat reflective barrier material for insulation jackets, welding curtains, heat shields, protective covers, and thermal protection panels.

Q2. Does it protect against radiant heat or direct flame

It is especially effective for radiant heat exposure because the aluminized surface reflects radiant energy. For direct flame exposure, performance depends on construction design and duration. For higher risk environments, multi layer solutions are recommended.

Q3. Can it be sewn into removable insulation jackets

Yes. It is commonly used as an outer reflective layer for removable insulation jackets, valve covers, and pipe blankets. Use appropriate high temperature sewing thread and reinforcement methods.

Q4. Which side should face the heat source

The reflective aluminized side should face the heat source to maximize radiant heat reflection.

Q5. Can you provide custom width and roll length

Yes. We can supply customized roll width and roll length to meet production needs and project requirements.

Q6. Is it suitable for automotive exhaust and turbo areas

Yes. It is widely used as a reflective heat barrier layer around exhaust zones, turbo areas, and engine compartments, especially where radiant heat management is needed.

Q7. How do I choose the right construction for my application

Share your heat source type, peak temperature, exposure time, installation method, and required size. We can recommend the best thickness, reinforcement, and matching insulation structure.

Q8. What factors affect service life

Service life depends on abrasion, vibration, bending frequency, chemical exposure, and installation method. If the application involves heavy abrasion, reinforced versions are recommended.
 

This aramid heat barrier is made from aramid 1414 and aluminum mylar finish. 
Aramid heat barrier can withstand up to 3000 degrees F of radiant heat and can withstand direct contact up to 800 degrees F.
This shield is capable of reflecting 90 percent of radiant heat. Face the aluminized side toward the source of radiant heat to shield heat away.
Use aramid heat barrier on Firewall, floor pan, under cab (above: muffler, catalytic convertor, DPF, exhaust system), fuel cel.
