Traditional Fuel Powered Vehicle Engine Compartment Insulation

Designed for high-temperature engine compartments, our composite material fuses PP woven fabric’s lightweight flexibility with fiberglass cloth’s superior heat resistance (up to 500°C sustained). The multi-layer structure efficiently blocks radiant heat (reducing surface temps by 30–40%), while enhancing mechanical durability to withstand vibrations and oil spills.
The PP layer offers chemical resistance and easy formability, ideal for complex engine bay geometries, while the fiberglass core provides structural rigidity and fire retardancy (UL94 V-0 rating). Lightweight yet robust (30% lighter than pure fiberglass insulation), it simplifies installation and reduces vehicle weight, improving fuel efficiency. Suitable for passenger cars and commercial vehicles, this eco-friendly solution balances thermal management, longevity, and cost-effectiveness in harsh under-the-hood environments.

Product Advantage

1. Superior High-Temperature Resistance & Thermal Blocking

Combining PP woven fabric with fiberglass cloth, our three-layer composite insulation features a fiberglass core capable of withstanding 500°C continuous heat (700°C peak) and a reflective film reducing radiant heat by 35–40%. Tested to UL94 V-0 fire rating, it protects engine components from thermal aging, extending the lifespan of wiring harnesses and plastic parts by 20%. Ideal for harsh under-hood environments.


2. Lightweight Strength for Vehicle Efficiency

At ≤500g/m², our material is 30% lighter than pure fiberglass, cutting vehicle weight to improve fuel economy. The composite structure offers 80N/mm tear strength (ASTM D638) and withstands 500,000+ vibration cycles, resisting cracks from engine motion. This balances durability with lightweight design, a critical advantage for OEMs focused on performance optimization.


3. Chemical Resistance for Long-Lasting Performance

The PP woven surface, coated with Teflon, boosts resistance to engine oils and coolants by 40% (ISO 17234), preventing material degradation from fluid spills. The alkali-free fiberglass core (≤0.8% Na2O/K2O) maintains thermal efficiency (<5% loss) through 1,000+ cycles of -40°C to 150°C testing, ensuring reliability in extreme climates.


4. Customizable Fit & Easy Installation

Leveraging 3D scanning, we provide vehicle-specific designs for complex engine bay geometries (minimum bend radius ≤50mm), with ultrasonic-welded edges for precision. Installation time is halved compared to traditional solutions—no adhesives needed—thanks to a clip-based system enabling 10-minute replacement, reducing assembly costs for manufacturers.


5. Eco-Compliance for Sustainable Mobility

Fully compliant with REACH, RoHS 2.0, and VDA 270 low-odor standards, our material contains no halogens or heavy metals. It’s 100% recyclable at end-of-life, with a production process that cuts energy use by 25% versus conventional methods, aligning with global ESG goals for greener automotive solutions.
