Stainless steel foil insulation is a high-performance heat shielding material designed to protect exhaust pipes and surrounding components from extreme temperatures, radiant heat, and thermal fatigue. Commonly used in automotive, truck, marine, and industrial exhaust systems, it offers superior durability, corrosion resistance, and long-term heat protection in harsh environments.

BSTFLEX stainless steel foil insulation combines thin metallic layers with advanced thermal barriers, providing both reflective and conductive heat resistance while maintaining flexibility for easy installation around complex exhaust geometries.

Key Features

1. Excellent Heat Reflection
The polished stainless steel foil surface reflects up to 95% of radiant heat, helping maintain lower surface and ambient temperatures around the exhaust pipe.

2. High-Temperature Resistance
Suitable for continuous exposure up to 650°C (1200°F) and short-term peaks above 800°C (1470°F), ensuring reliable performance even in turbocharged or heavy-duty exhaust systems.

3. Durable and Corrosion-Resistant
Unlike aluminum foil or fiber wraps, stainless steel foil resists oxidation, oil, road salt, and vibration damage, extending service life under demanding conditions.

4. Mechanical Strength and Protection
Provides excellent shielding against abrasion, impact, and moisture — ideal for under-vehicle applications and off-road machinery.

5. Easy to Form and Secure
The foil can be pre-shaped, folded, or wrapped directly over exhaust components using clamps, rivets, or high-temperature fasteners, allowing for custom fitment and easy maintenance.

Typical Applications

• Automotive and motorcycle exhaust pipe insulation

• Turbocharger heat shields and downpipe covers

• Diesel generator and marine exhaust systems

• Industrial furnaces and high-temperature ducting

• Aircraft and motorsport exhaust systems

Product Construction Options

BSTFLEX offers several construction formats to meet different thermal management requirements:

• Single-layer stainless steel foil wrap – For basic radiant heat reflection.

• Multi-layer stainless foil + ceramic fiber blanket – For higher insulation efficiency and noise damping.

• Stainless foil + silica or fiberglass mat – For flexibility and vibration absorption.

• Embossed stainless steel foil – Enhances structural strength and appearance while reducing glare.

Benefits in Exhaust System Performance

Using stainless steel foil insulation helps:

• Reduce heat transfer to nearby components and sensors

• Maintain optimal exhaust gas temperatures, improving engine efficiency

• Protect wiring, hoses, and body panels from radiant heat damage

• Enhance operator safety and comfort by lowering ambient heat

• Prolong component life and reduce maintenance downtime
